Description
The AP22913 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 RDS(ON) of 54mat
5V(X1-WLB0909-4), allowing increased load current
handling capacity with a low forward voltage drop.
The turn-on slew rate of the device is controlled
internally. VIN and VOUT are isolated during OFF state
with TRCB (True Reverse Current Blocking) feature.
The AP22913 load switch is designed to operate
from 1.4V to 5.5V, making it ideal for 1.8V, 2.5V, 3.3V,
and 5V systems. The typical quiescent supply
current is only 1µA.
The AP22913 is available in the wafer level chip
scale 4-pin, X1-WLB0909-4 0.5mm pitch package.

Quick Start Guide
AP22913 is a single p-channel MOSFET load switch. It has an input voltage range between 1.4V to
5.5V and is capable of handling up to 2A continuous current. The board demonstrates the AP22913’s
current handling capacity with its controlled turn on, low RDS(on) and very low quiescent current specification.
All inputs and output are brought out to test points for control and monitoring. All passive components are
included on the EVM for device operation.
1. Connect a power supply between IN and GND terminals.
2. Connect the positive connection to the IN and the negative connection to the GND.
3. Connect an adjustable current or resistive load to OUT and GND terminals.
4. Connect the positive connection of the load to the OUT and the negative connection to the GND.
5. IN via reserved resistor R1 connect to ON terminal or installed shorting jumper on J1 in either the Hi or Lo
positions. The default is shorted directly between IN and ON terminals.
6. Turn on the power supply.
7. Increase the load current of OUT and observe that the load current stop increasing after reaching limit
level.
