MAX16000-MAX16007 General Description The MAX16000-MAX16007 are low-voltage, quad/hex/ octal-voltage P supervisors in small TQFN 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. 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-pin TQFN and 16-pin TSSOP packages. These are fully specified from -40C to +125C.

The timer clears whenever a reset is asserted or a rising or falling edge on WDI is detected. The watchdog timer enters a startup period that allows 54s for the first transition to occur before a reset. Leave WDI unconnected to disable the watchdog timer. The WDI openstate detector uses a small 400nA current. Therefore, do not connect WDI to anything that will source or sink more than 200nA.

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. 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 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). Low-Voltage, Quad/Hex/Octal-Voltage P Supervisors 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 V1 IN1 V2 IN2 V3 IN3 V4 IN4 VCC MAX16000 MAX16001 OUT1 OUT2 OUT3 OUT4 GND Figure 6.

Setting the Adjustable Input R3 V R4 TH Adjustable Input 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. Figure 8. Window Detection OUT1 V TH1 OUT4 V TH4 R1 = R2 ((VINTH / VTH) - 1) Large resistors can be used to minimize current through the external resistors. For greater accuracy, use lowervalue resistors.

Output Response of Window Detector Circuit www.maximintegrated.com VINTH = VTH ((R1 / R2) + 1) 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).

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.

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 C SRT (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 MR to GND to create a manual www.maximintegrated.com 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.
