DESCRIPTION

SiP32413 and SiP32414 are slew rate controlled load

switches that is designed for 1.1 V to 5.5 V operation.

The devices guarantee low switch on-resistance at 1.2 V

input. They feature a controlled soft-on slew rate of typical

150 µs that limits the inrush current for designs of capacitive

load or noise sensitive loads.

The devices feature a low voltage control logic interface (On/

Off interface) that can interface with low voltage digital

control without extra level shifting circuit. The SiP32414 also

integrates output discharge switches that enable fast

shutdown load discharge. When the switches are off, they

provide the reverse blocking to prevent high current flowing

into the power source.

Both the SiP32413 and SiP32414 are available in TDFN8

2 mm x 2mm package. Each switch in each device can

support over 2 A of continuous current.
