AP22908

1.5A Single Slew Rate Controlled Load Switch

Contact Sales

Description

The AP22908 slew rate controlled load switch is a single P-channel MOSFET power switch designed for high-side load-switching applications. The MOSFET has a typical low RDS(ON) of 28mΩ at 3.6V, allowing increased load current handling capacity with a low forward voltage drop. The turn-on slew rate of the device is controlled internally to avoid inrush current.

The AP22908 load switch is designed to operate from 1.08V to 3.6V, making it ideal for 1.2V, 1.8V, 2.5V, 3.3V and 3.6V systems. The typical quiescent supply current is only 0.05μA. The AP22908 is available in the wafer level chip scale 4-pin, X1-WLB0909-4 0.5mm pitch and standard SOT26.
