DESCRIPTION

SiP32452 and SiP32453 are n-channel integrated high side

load switches that operate from 0.9 V to 2.5 V input voltage

range.

SiP32452 and SiP32453 has 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 in less than 25 µs typically for input

voltage of 1.2 V or higher. SiP32452 has 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.

Both SiP32452 and SiP32453 are available in compact

0.8 mm x 0.8 mm with 0.4 mm pitch.
