AP22916 1.3V-5.5V, 2A, 60m ULTRA-LOW LEAKAGE LOAD SWITCH Description Pin Assignments The AP22916 is a small, low leakage, single P-channel power MOSFET designed for low-power consumption, load-switching applications. The X1-WLB0808-4 power MOSFET has a typical R of 60m at 5V, allowing increased DS(ON) load current handling capacity with a low forward voltage drop. Multiple voltages correspond to different time options to support various system load conditions. The trigger of the load switch ON pin can be controlled to be enabled or disabled by an external low voltage digital signal for sequence control application. Smart pull down feature is built in the ON pin. Once the enable voltage is higher than V , it will disconnect to IH avoid power loss. V and V are isolated during OFF state with the IN OUT TRCB (Truly Reverse Current Blocking) feature. Top View Bottom View The AP22916 load switch is designed to operate from 1.3V to 5.5V, making it ideal for 1.3V, 1.8V, 2.5V, 3.6V, and 5V systems. The typical quiescent supply current is only 0.5A. The AP22916 is available in the wafer level chip scale 4-pin, X1- WLB0808-4 0.78mm x 0.78mm x 0.455mm, 0.4mm pitch package. The device is characterized for operation over a temperature range of 40C to +85C.
