Dual 2 A, 1.2 V, Slew Rate Controlled Load Switch

DESCRIPTION

SiP32413, SiP32414 and SiP32416 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. SiP32413 and SiP32414 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. SiP32416

features a longer slew rate of typical 2.5 ms to keep the peak

of the inrush current even lower.

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 and

SiP32416 also integrate 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.

All SiP32413, SiP32414 and SiP32416 are available in

TDFN8 2 mm x 2 mm package. Each switch in each device

can support over 2 A of continuous current.
