Description

The AP22916 is a small, low leakage, single P-channel power MOSFET designed for low-power consumption and load-switching applications. This power MOSFET has a typical R_DS(ON)of 60mΩ at 5V, allowing increased 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. The smart, pull down feature is built into the ON pin. Once the enable voltage is higher than V_IH, it will disconnect to avoid power loss. V_IN and V_OUT are isolated during OFF state with the TRCB (true reverse current blocking) feature.

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 0.5µA.

The AP22916 is available in the wafer-level chip-scale 4-pin, U-WLB0808-4 (Type B) 0.78mm x 0.78mm x 0.455mm, 0.4mm pitch package. The device is characterized for operation over a temperature range of -40°C to +85°C.
