New Low-Voltage, High-Side Load Switch

Diodes Incorporated has announced the introduction of the AP22913, a 2A single-channel, slew-rate-controlled load switch with true reverse current blocking for high-side load-switching applications.

Single-channel high-side load switches provide an effective way of applying or removing power to a load, particularly to removable peripherals powered through a USB port.

The AP22913A load switch incorporates true reverse current blocking, which removes the normal body diode unwanted current paths to provide a solution to load switching.

With a load current of up to 2A across a wide operating voltage range, the AP22913 is designed to deliver a typical Rds(on) of 92mΩ at 1.5V and 54mΩ at 5.0V. The firm claims this achieves maximum load current handling capacity with a low forward voltage drop.

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 true reverse current blocking when disabled and in its off state, the vin and vout terminals are completely isolated internally.

The AP22913 load switch is designed to operate from 1.4-5.5V and consumes a quiescent current of 1µA, making it suited for 1.8V, 2.5V, 3.3V, and 5V systems. With a maximum load current of 2A, the AP22913 is suitable for applications in smart phones, portable, wearable and medical devices, and navigation devices as well as notebooks and ultra-mobile PCs.

The AP22913 is available in options including the AP22913CN4-7, which is housed in the X-WLB0909-4 package, and the AP22913W6-7, which is available in the SOT26 package, both in 1000 unit quantities.
