DATA SHEET AAT4616: Ultrahigh Precision Adjustable Current Limited Load Switch with Fault Flag Applications Description USB ports The AAT4616 SmartSwitch is a current-limit P-channel MOSFET power switch designed for high-side load switching applications. This switch operates with inputs ranging from 2.4 V to 5.5 V, making it ideal for both 3 V and 5 V systems. An integrated, highly accurate current-limit circuit protects the input supply against large currents, which may cause the supply to fall out of regulation. Reverse current blocking is provided to protect the load switch from reverse current flows while the device is in shutdown. Portable products Hot-swap supplies Notebook computers Proprietary peripheral ports Features Input voltage: 2.4 V to 5.5 V The AAT4616 is also protected from thermal overload, which limits power dissipation and junction temperature. Current-limit threshold is programmed with a resistor from SET to ground, and is adjusted for load levels up to 1.6 A. The ultrafast current limit response to a sudden short circuit is 2 s, which reduces the requirements of local supply bypassing. An open-drain FAULT flag signals an over-current or over-temperature condition. To prevent false reporting, a 4 ms time interval is used at startup (charging a capacitive load), where fault conditions are not monitored and reported. Quiescent current is a low 10 A and the supply current decreases to less than 1 A in shutdown mode. Programmable over-current limit setting: 300 mA to 1.6 A 10% current limit precision at 750 mA Fast transient response: 2 s response to short circuit Low quiescent current: 10 A typical while enabled 1 A maximum with switch off 130 m typical RDS(ON) Under-voltage lockout (UVLO) Reverse blocking during disable The AAT4616 is offered in small Pb-free, 5-pin SOT23-5 and TDFN22-8 packages, and is specified for operation over the -40C to +85C ambient temperature range. 4 ms fault masking at startup (capacitive load) Fault flag open-drain output A typical application circuit is shown in Figure 1.

AAT4616 Functional Block Diagram Functional Description The AAT4616 is a single-channel current-limit load switch that is intended to protect against short-circuit and over-current events by current limiting to a preset level. This device also provides a reverse current blocking feature, on/off enable control, and a fault flag to notify a system controller of an over-current, short-circuit, or over-temperature events. In the event of a load current exceeding a programmed current limit level (ILIM), a high-speed current limit loop limits the current in a microsecond and resets to low impedance once the short circuit condition is removed. The AAT4616 is internally protected from thermal damage by an over-temperature detection circuit. If the die temperature reaches the internal thermal limit, the power device is switched off until the die temperature cools to a level below the thermal limit threshold. This device may operate in a thermal cycling state indefinitely or until the over-current condition is removed. The AAT4616 operates with input voltages ranging from 2.4 V to 5.5 V which, along with its extremely low operating current, makes it ideal for battery-powered applications. In cases where the input voltage drops below 2.4 V, the AAT4616 MOSFET is protected from entering the saturated region of operation by being automatically shut down by the under-voltage lockout circuit. Current limit or over-temperature conditions are reported by the open drain FAULT output. A 4 ms masking interval prevents false reporting during the charging of a capacitive load, which typically occurs during device turn-on, but may also occur during a port hot plug-in event. The AAT4616 is ideally suited for protection of peripheral ports such as USB, RS232, and parallel ports. Figure 15 shows the functional block diagram. Reverse Current Blocking The reverse current blocking feature prevents current flowing from OUT to IN when the device is disabled. When the device is enabled, the electrical characteristics between IN and OUT is still similar to an ideal switch, and current can flow in either direction. Application Information Setting Current Limit The AAT4616 current limit can be set by an external resistor (RSET) connected from the SET pin to GND. RSET can be calculated by the following equation: RSET 750 mA 6 k I LIM where ILIM is in mA and RSET in k. Table 5 summarizes resistor values for current limit settings. Use 1% tolerance metal film resistors for programming the desired current limit setting. Figure 16 shows the output current vs. output voltage with RSET equal to 6.04 k.

Recommended 1% Tolerance Metal Film Resistors RSET for Current Limit RSET (k) Current Limit (mA) large the output capacitor, the output current is limited to the value set by the AAT4616 current-limit circuitry, so very large output capacitors can be used. For example, USB ports are specified to have at least 120 F of capacitance downstream from their controlling power switch. The current limiting circuit allows an output capacitance of 1000 F or more without disturbing the upstream power supply. 15 300 8.87 500 6.04 750 4.53 1000 3.74 1200 ON/ON (Enable Input) 3.09 1400 2.8 1600 In many systems, power planes are controlled by integrated circuits that run at lower voltages than the power planes themselves. The enable input (ON/ON) of the AAT4616 has lowand high-threshold voltages that accommodate this condition. The threshold voltages are compatible with 5 V TTL and 2.5 V 5 V CMOS systems. 1 Current Limit (A) 0.8 0.6 Both active-high and active-low options are available for all packages. 0.4 Connecting to Capacitive Load When switching the AAT4616 onto a capacitive load, the AAT4616 charges the output capacitive load at a rate no greater than the current limit setting. 0.2 0 1 2 3 4 5 Output Voltage (V) Figure 16. Current Limit vs Output Voltage (VIN = 5.0 V, TA = 25 C, RSET = 6.04 k) Input Capacitor The input capacitor CIN protects the power supply from current transients generated by the load attached to the AAT4616. When a short circuit is suddenly applied to the output of the AAT4616, a large current, limited only by the RDS(ON) of the MOSFET, flows for less than 1 s before the current limit circuitry activates. In this event, a moderately sized CIN dramatically reduces the voltage transient seen by the power supply and by other circuitry upstream from the AAT4616. The extremely fast short-circuit response time of the AAT4616 reduces the size requirement for CIN. CIN should be located as close to the device VIN pin as practically possible. Ceramic, tantalum, or aluminum electrolytic capacitors are appropriate for CIN. There is no specific capacitor Equivalent Series Resistance (ESR) requirement for CIN. For higher current operation, ceramic capacitors are recommended for CIN due to their inherent capability over tantalum capacitors to withstand input current surges from low impedance sources such as batteries in portable devices. Output Capacitor In order to ensure stability while current limit is active, a low capacitance (approximately 0.47 F) is required. No matter how FAULT Output The FAULT Flag (FLT) is provided to alert the system if an AAT4616 load is not receiving sufficient voltage to operate properly. If current limit or over-temperature circuits in any combination are active for more than approximately 4 ms, the FAULT Flag is pulled to ground through an approximately 100 resistor. The filtering of voltage or current transients of less than 4 ms prevents capacitive loads connected to the AAT4616 output from activating the FAULT Flag when they are initially attached. Pull-up resistances of 10 k to 100 k are recommended. Since FLT is an open-drain terminal; it may be pulled up to any unrelated voltage less than the maximum operating voltage of 5.5 V, allowing for level shifting between circuits. Thermal Considerations Since the AAT4616 has internal current limit and overtemperature protection, junction temperature is rarely a concern. However, if the application requires large currents in a hot environment, it is possible that temperature, rather than current limit, is the dominant regulating condition. In these applications, the maximum current available without risk of an overtemperature condition must be calculated. The maximum internal temperature while current limit is not active can be calculated using the following equation: 2 TJ ( MAX ) I MAX ( OUT ) _ SW ( MAX ) R DS ( ON )( MAX ) RJA T A( MAX ) (1) where: Skyworks Solutions, Inc. * Phone [781] 376-3000 * Fax [781] 376-3100 * sales@skyworksinc.com * www.skyworksinc.com 201940D * Skyworks Proprietary Information * Products and Product Information are Subject to Change Without Notice * August 14, 2013 7 DATA SHEET * AAT4616 ULTRAHIGH PRECISION ADJUSTABLE CURRENT LIMITED LOAD SWITCH WITH FAULT FLAG IMAX is the maximum current required by the load.

I MAX RJA is the thermal resistance between the AAT4616 die and the board onto which it is mounted.
