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

enabling current handling capability of up to 4A.

The AP22800 is designed to operate from 1.5V to 5.5V making it ideal

for 1.8V, 2.5V, 3.3V, 5V voltage rails. The low quiescent supply

current specification of 21µA 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.
