19-3870; Rev 5; 10/10 Low-Voltage, Quad-/Hex-/Octal-Voltage P Supervisors Features The MAX16000-MAX16007 are low-voltage, quad-/hex-/ octal-voltage P supervisors in small thin QFN and TSSOP packages. These devices provide supervisory functions for complex multivoltage systems. The MAX16000/ MAX16001/MAX16002 monitor four voltages, the MAX16003/MAX16004/MAX16005 monitor six voltages, and the MAX16006/MAX16007 monitor eight voltages. o Fixed Thresholds for 5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V Systems o Adjustable Thresholds Monitor Voltages Down to 0.4V o Open-Drain Outputs with Internal Pullups Reduce the Number of External Components o Fixed 140ms (min) or Capacitor-Adjustable Reset Timeout o Manual Reset, Margin Enable, and Tolerance Select Inputs o Watchdog Timer 1.6s (typ) Timeout Period 54s Startup Delay After Reset (Except MAX16005) o Independent Watchdog Output (MAX16005) o RESET Output Indicates All Voltages Present o Independent Voltage Monitors o Guaranteed Correct Logic State Down to VCC = 1V o Small (4mm x 4mm) Thin QFN Package o TSSOP (5mm x 4.4mm) Package (MAX16005) The MAX16000/MAX16001/MAX16003/MAX16004/ MAX16006 offer independent outputs for each monitored voltage. The MAX16001/MAX16002/MAX16004- MAX16007 offer a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30A pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing. The MAX16001/MAX16002/MAX16004-MAX16007 offer a watchdog timer that asserts RESET or an independent watchdog output (MAX16005) when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving the input open. These devices are offered in 12-, 16-, 20-, and 24-lead thin QFN and 16-lead TSSOP packages. These are fully specified from -40C to +125C. Ordering Information PART MAX16000_TC+ TEMP RANGE PIN-PACKAGE -40C to +125C 12 TQFN-EP* Note: The "_" is a placeholder for the input voltage threshold.

These devices provide supervisory functions for complex multivoltage systems. The MAX16000/ MAX16001/MAX16002 monitor four voltages, the MAX16003/MAX16004/MAX16005 monitor six voltages, and the MAX16006/MAX16007 monitor eight voltages. The MAX16000/MAX16001/MAX16003/MAX16004/ MAX16006 offer independent outputs for each monitored voltage. The MAX16001/MAX16002/MAX16004- MAX16007 offer a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30A pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing. Window Detection A window detector circuit uses two auxiliary inputs in the configuration shown in Figure 8. External resistors set the two threshold voltages of the window detector circuit. External logic gates create the OUT signal. The window detection width is the difference between the threshold voltages (Figure 9). 5V VCC V1 IN1 V2 IN2 V3 IN3 V4 IN4 MAX16000 MAX16001 OUT1 OUT2 OUT3 OUT4 GND Figure 6. Quad Undervoltage Detector with LED Indicators The MAX16001/MAX16002/MAX16004-MAX16007 offer a watchdog timer that asserts RESET or an independent watchdog output (MAX16005) when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving input open. Applications Information 5V D1 VIN(5V) VCC OUT1 D2 IN1 Undervoltage-Detection Circuit The open-drain outputs of the MAX16000-MAX16007 can be configured to detect an undervoltage condition. Figure 6 shows a configuration where an LED turns on when the comparator output is low, indicating an undervoltage condition. These devices can also be used in applications such as system supervisory monitoring, multivoltage level detection, and VCC bar-graph monitoring (Figure 7). Tolerance (TOL) The MAX16000-MAX16007 feature a pin-selectable threshold tolerance. Connect TOL to GND to select 5% threshold tolerance. Connect TOL to VCC to select 10% threshold tolerance. 18 OUT2 IN2 D3 IN3 MAX16000 MAX16001 OUT3 D4 IN4 GND OUT4 Figure 7.

Window Detection OUT1 V TH1 These devices offer several monitor options with adjustable input thresholds (see Table 1). The threshold voltage at each adjustable IN_ input is typically 0.394V (TOL = GND) or 0.372 (TOL = VCC). To monitor a voltage VINTH, connect a resistive-divider network to the circuit as shown in Figure 10. VINTH = VTH ((R1 / R2) + 1) R1 = R2 ((VINTH / VTH) - 1) Large resistors can be used to minimize current through the external resistors. For greater accuracy, use lowervalue resistors. Unused Inputs OUT4 V TH4 Connect any unused IN_ inputs to a voltage above its threshold. OUT_ Outputs (MAX16000/MAX16001/MAX16003/ MAX16004/MAX16006) OUT V TH Figure 9. Output Response of Window Detector Circuit The OUT_ outputs go low when their respective IN_ inputs drop below their specified thresholds. The output is open drain with a 30A internal pullup to VCC. For many applications, no external pullup resistor is required to interface with other logic devices. An external pullup resistor to any voltage from 0 to 5.5V overrides the internal pullup if interfacing to different logic supply voltages. Internal circuitry prevents reverse current flow from the external pullup voltage to VCC (Figure 11). ______________________________________________________________________________________ 19 MAX16000-MAX16007 ( R1 VTH1 = 1 + R2 MAX16000-MAX16007 Low-Voltage, Quad-/Hex-/Octal-Voltage P Supervisors VCC = 3.3V 5V IN_ VTH_ VTH_ 100k VCC VCC RESET OUT_ 90% 10% RESET tRD tRP OUT_ 90% MAX16001/ MAX16002/ MAX16004-MAX16007 GND 10% GND Figure 11. Interfacing to a Different Logic Supply Voltage RESET Output (MAX16001/MAX16002/ MAX16004-MAX16007) RESET asserts low when any of the monitored voltages fall below their respective thresholds or MR is asserted. RESET remains asserted for the reset timeout period after all monitored voltages exceed their respective thresholds and MR is deasserted (see Figure 12). This open-drain output has a 30A internal pullup. An external pullup resistor to any voltage from 0 to 5.5V overrides the internal pullup if interfacing to different logic supply voltages. Internal circuitry prevents reverse current flow from the external pullup voltage to VCC (Figure 11). 20 tD tD Figure 12. Output Timing Diagram WDO (MAX16005 Only) WDO asserts and stays low whenever any of the IN_ inputs fall below their respective thresholds. WDO deasserts without a timeout delay when all the IN_ inputs rise above their thresholds. When all the IN_ inputs rise above their thresholds, WDO asserts low whenever the watchdog timer times out. WDO deasserts after a valid WDI transition or if MR is pulled low. The watchdog timer begins counting after the reset timeout period once MR goes high. Pull MARGIN low to deassert WDO regardless of any other condition. The watchdog timer continues to run when MARGIN is low and if a timeout occurs. WDO will assert MR after MARGIN is deasserted. This open-drain output has a 30A internal pullup. An external pullup resistor to any voltage from 0 to 5.5V overrides the internal pullup if interfacing to different logic supply voltages.

Margin Output Disable (MARGIN) Affect on RESET Outside tRP Reset Timeout Capacitor The reset timeout period can be adjusted to accommodate a variety of P applications from 50s to 1.12s. Adjust the reset timeout period (tRP) by connecting a capacitor (CSRT) between SRT and GND. Calculate the reset timeout capacitor as follows: t (s) x ISRT CSRT (F) = RP VTH _ SRT Connect SRT to VCC for a factory-programmed reset timeout of 140ms (min). Manual Reset Input (MR) (MAX16001/MAX16002/ MAX16004-MAX16007) Many P-based products require manual reset capability, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic-low on MR asserts RESET low. RESET remains asserted while MR is low, and during the reset timeout period (140ms min) after MR returns high. The MR input has an internal 20k pullup resistor to VCC, so it can be left unconnected if not used. MR can be driven with TTL or CMOS-logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from 22 MR to GND to create a manual reset function. External debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1F capacitor from MR to GND provides additional noise immunity. Margin Output Disable (MARGIN) MARGIN allows system-level testing while power supplies are adjusted from their nominal voltages. Drive MARGIN low to force RESET, WDO, and OUT_ high, regardless of the voltage at any monitored input. The state of each output does not change while MARGIN = GND. The watchdog timer continues to run when MARGIN is low, and if a timeout occurs, WDO/RESET will assert tMD after MARGIN is deasserted. The MARGIN input is internally pulled up to VCC. Leave MARGIN unconnected or connect to VCC if unused. Power-Supply Bypassing The MAX16000-MAX16007 operate from a 2.0V to 5.5V supply. An undervoltage lockout ensures that the outputs are in the correct states when the UVLO is exceeded. In noisy applications, bypass VCC to ground with a 0.1F capacitor as close to the device as possible. The additional capacitor improves transient immunity. For VCC transients with high slew rates, place an RC lowpass filter in front of VCC, where R can be up to 100. ______________________________________________________________________________________ Low-Voltage, Quad-/Hex-/Octal-Voltage P Supervisors IN1 10 IN2 11 OUT4 IN1 10 5 OUT3 IN2 11 4 VCC TOL 12 SRT 7 MAX16002 1 2 3 1 MR 5 VCC 4 GND GND IN3 2 3 9 MARGIN 10 OUT3 SRT 11 OUT2 MARGIN 12 TOP VIEW OUT1 OUT2 THIN QFN (4mm x 4mm) OUT1 THIN QFN (4mm x 4mm) TOP VIEW 6 + IN4 + 8 IN3 TOL 12 MAX16000 6 9 WDI 7 MARGIN MARGIN 8 IN4 OUT2 9 TOP VIEW RESET OUT1 TOP VIEW 12 11 10 9 RESET 13 8 MR IN1 13 8 OUT6 IN1 14 7 OUT4 IN2 14 7 OUT5 6 OUT3 IN3 15 6 OUT4 5 VCC TOL 16 5 VCC 4 1 GND IN4 THIN QFN (4mm x 4mm) 2 3 4 GND 3 IN6 2 WDI 1 + IN4 + IN3 TOL 16 MAX16003 IN5 MAX16001 IN2 15 THIN QFN (4mm x 4mm) ______________________________________________________________________________________ 23 MAX16000-MAX16007 Pin Configurations Low-Voltage, Quad-/Hex-/Octal-Voltage P Supervisors 18 RESET 16 10 MR IN1 17 9 OUT6 8 OUT5 7 OUT4 6 VCC SRT 11 MARGIN 12 OUT4 SRT 13 OUT3 MARGIN 14 OUT2 OUT3 15 TOP VIEW 17 16 15 14 13 OUT1 OUT2 TOP VIEW OUT1 MAX16000-MAX16007 Pin Configurations (continued) RESET 19 12 MR IN1 20 11 OUT8 10 OUT7 9 OUT6 8 OUT5 7 VCC IN2 21 IN2 18 MAX16004 MAX16006 IN3 22 IN3 19 IN4 23 TOL 20 + + 1 2 WDI GND IN5 IN6 4 5 RESET MARGIN SRT MR 12 11 10 9 TOP VIEW + IN1 13 8 WDO IN2 14 7 REF 6 VCC IN3 1 16 IN2 TOL 2 15 IN1 IN4 3 4 IN5 IN6 WDI TOP VIEW THIN QFN (4mm x 4mm) SRT 3 MARGIN 2 N.C. 1 GND N.C. 5 + IN4 TOL 16 IN5 4 RESET MAX16005 IN3 15 6 THIN QFN (4mm x 4mm) THIN QFN (4mm x 4mm) TOP VIEW 3 GND 5 WDI 4 IN8 3 IN7 2 IN6 IN4 1 IN5 TOL 24 15 14 13 12 11 IN6 5 12 SRT 11 MR GND 7 10 WDO VCC 8 9 REF TSSOP 10 MR IN2 17 9 N.C. 8 N.C. 7 VCC 6 GND MAX16007 IN4 19 2 3 4 5 IN8 WDI IN5 1 IN7 + IN6 TOL 20 13 MARGIN WDI 6 IN1 16 IN3 18 14 RESET MAX16005 THIN QFN (4mm x 4mm) 24 ______________________________________________________________________________________ Low-Voltage, Quad-/Hex-/Octal-Voltage P Supervisors PART TEMP RANGE Chip Information PROCESS: BiCMOS PIN-PACKAGE MAX16001_TE+ -40C to +125C 16 TQFN-EP* MAX16002_TC+ -40C to +125C 12 TQFN-EP* MAX16003_TE+ -40C to +125C 16 TQFN-EP* MAX16004_TP+ -40C to +125C 20 TQFN-EP* MAX16005_TE+ -40C to +125C 16 TQFN-EP* MAX16005_UE+ -40C to +125C 16 TSSOP MAX16006_TG+ -40C to +125C 24 TQFN-EP* MAX16007_TP+ -40C to +125C 20 TQFN-EP* Note: The "_" is a placeholder for the input voltage threshold.
