Diodes Incorporated introduced the AP22913, a 2.0A single-channel, slew-rate-controlled load switch with true reverse current blocking (TRCB) for high-side load-switching applications. TRCB 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, with a maximum load current of 2.0A. The AP22913 is available in options including the AP22913CN4-7, which is housed in the X-WLB0909-4 package and priced at $0.10, and the AP22913W6-7, which is available in the SOT26 package and priced at $0.10, both in 1000 unit quantities.
