AP22800
5V SINGLE CHANNEL PROGRAMMABLE LOAD SWITCH Description
The AP22800 is an integrated N-channel load switch, which features an adjustable ramp-up and discharge rate that are settable via an external capacitor and a resistor, respectively. In addition, it incorporates a `power good' output to flag when the switch is enhanced. The N-channel MOSFET has a typical RDS(ON) of 19m, enabling current handling capability of up to 6A.
