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.
