High-Side Load Switch from Diodes Incorporated with Slew-Rate Control and True Reverse Current Blocking Improves Reliability

Diodes Incorporated (Nasdaq: DIOD) today announced the introduction of the AP22913, a 2.0A single-channel, slew-rate-controlled load switch with true reverse current blocking (TRCB) 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 large output capacitors (100µF) associated with the USB port and self-powered USB peripherals create the possibility that the load switch may become reverse-biased, which creates the potential of reverse current flowing from the load to the source, potentially causing damage to other components or active cables. The AP22913A load switch incorporates TRCB, which removes the normal body diode unwanted current paths to provide a cost-effective and space-efficient solution to load switching.

With a load current of up to 2.0A 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, allowing 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 TRCB 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 1.4V to 5.5V and consumes a quiescent current of just 1µA, making it well-suited for 1.8V, 2.5V, 3.3V, and 5.0V systems. With a maximum load current of 2.0A, the AP22913 is suitable for a wide range of applications, such as smart phones, 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.
