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 16mΩ,
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.
