AAT4252A Dual Slew Rate Controlled Load Switch

The AAT4252A SmartSwitch™ is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 105mW, allowing increased load switch current handling capacity with a low forward voltage drop. The device is available in three different versions with flexible turn-on and turn-off characteristics–from very fast to slew-rate limited. The standard 4252A (-1) version has a slew-rate limited turn-on load switch. The AAT4252A (-2) version features a fast turn-on capabilities, typically less than 500ns turn-on and 3μs turn-off times. The AAT4252A (-3) variation offers a shutdown load discharge circuit to rapidly turn-off a load circuit when the switch is disabled. An additional feature is a slew-rate selector pin which can switch between fast and slow slew rate. All the AAT4252A load switch versions are designed to operate from 1.5V up to 6.5V, making then ideal for both 3V and 5V systems. Input logic levels are TTL and 2.5V to 5V CMOS compatible. The quiescent supply current is a very low 500nA. The AAT4252A is available in the Pb-free TSOPJW-12 package and is specified over the -40°C to +85°C temperature range.
