Vishay Siliconix's SiP3245x High-Side Load Switches are n-channel integrated high side load switches that operate from 0.9V to 2.5V input voltage range. The SiP3245x 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 25μs typically for input voltage of 1.2V or higher. SiP32451 and SiP32452 have fast turn off delay time of less than 1μs while SiP32453 features a guaranteed turn off delay of greater than 30μs, typically 90μs.
