Vishay Siliconix
0.9 V to 2.5 V, 55 m Load Switch in WCSP4
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.
