DESCRIPTION

SiP32451, SiP32452 and SiP32453 are n-channel integrated

high side load switches that operate from 0.9 V to 2.5 V input

voltage range.

SiP32451, SiP32452 and SiP32453 have low input logic

control threshold that can interface with low voltage control

GPIO directly without extra level shift or driver. There is a pull

down at this EN logic control pin.

Turn on time is fast, less than 25 µs typically for input

voltage of 1.2 V or higher. SiP32451 and SiP32452 have

fast turn off delay time of less than 1 µs while SiP32453

features a guaranteed turn off delay of greater than 30 µs,

typically 90 µs.

SiP32451 features an output discharge for fast turn off.

SiP32451, SiP32452 and SiP32453 are available in compact

wafer level CSP package, WCSP4 0.8 mm x 0.8 mm with

0.4 mm pitch.
