Description
AP22850 is an integrated P-Channel load switch, which features an adjustable ramp-up and discharge rate that can be set via an external capacitor and a resistor, respectively. In addition, it incorporates a “power good” output to flag when the switch is fully enhanced. The PChannel switch has a typical RDS(ON) of 21mΩ, enabling a current handling capability of up to 8A.
AP22850 is designed to operate from 4.5V to 11V. The near-zero quiescent supply current makes it ideal for use in battery powered distribution systems where power consumption is a concern.
Even as a P-Channel load switch, AP22850 does not require an external gate pull-up resistor, and consequently, stays true to its headlining feature of near-zero quiescent current specification. It also features circuitry to suppress fast input transients (with EN low) from coupling to VOUT.
