AP22913- Slew Rate Controlled 2A P-Channel MOSFET for high-side Load Switching

Diodes Incorporated has introduced AP22913, a 2.0A single-channel, slew-rate-controlled load switch with true reverse current blocking (TRCB) for high-side load switching applications. The AP22913 can easily apply or remove the power to the load, especially in removable peripherals powered through a USB port.  The large output capacitors (100µF) along with the USB Port and self-powered USB create the possibilities of reverse-biasing where the reverse current starts flowing from the load to the source, this might cause damages to the other components or active cables. The AP22913 has a TRCB that removes the normal body diode unwanted current paths to provide a cost-effective and space-efficient solution to load switching.


Features of AP22913:

  • Load current: 2A
  • Wide operating voltage range of 1.4V to 5.5V
  • RDS (ON): 92mΩ at 1.5V and 54mΩ at 5.0V
  • Maximum load current handling capacity with a low forward voltage drop
  • Consumes a quiescent current of just 1µA
  • 1.8V, 2.5V, 3.3V, and 5.0V systems


The turn-on slew rate of the device is controlled internally to provide a soft-start feature for sensitive loads while the device also features an active-high enable input to enable load switching. To ensure TRCB when disabled and in it’s off state, the VIN and VOUT terminals are completely isolated internally.


AP22913 is suitable for a wide range of applications such as Smartphones, portable, wearable and medical devices, and navigation devices as well as notebooks and ultra-mobile PCs. The AP22913 is available in two options: the AP22913CN4-7 in the X-WLB0909-4 package and the AP22913W6-7 in the SOT26 package.
