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.

The low quiescent supply current specification makes it ideal for use in battery powered distribution systems where power consumption is a concern. The AP22800 is available in a standard Green U-DFN2116-8 package with an exposed PAD for improved thermal performance and is RoHS compliant.
