1.1 V to 5.5 V, Slew Rate Controlled Load Switch

DESCRIPTION

SiP32401A and SiP32402A are slew rate controlled load

switches 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

2.5 ms that limits the inrush current for designs of heavy

capacitive load and minimizes the resulting voltage droop at

the power rails.

These devices feature low voltage control logic interface

(On/Off interface) that can interface with low voltage control

signal without extra level shifting circuit. SiP32402A also

integrates an output discharge switch that enables fast

shutdown load discharge.

Both SiP32401A and SiP32402A have exceptionally low

shutdown current and provide reverse blocking to prevent

high current flowing into the power source.

SiP32401A and SiP32402A are in TDFN4 package of

1.2 mm by 1.6 mm.
