By Vishay/Siliconix 42
Vishay/Siliconix's SiP32452 and SiP32453 are n-channel integrated high side load switches that operate within the 0.9 V to 2.5 V input voltage range.
SiP32452 and SiP32453 have a low input logic control threshold that can interface with low voltage control GPIO's directly without extra level shifting or drivers. 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. SiP32452 has a fast turn off delay time of less than 1 µs, while the SiP32453 features a guaranteed turn off delay of greater than 30 μs, typically 90 µs. Both SiP32452 and SiP32453 are available in compact wafer level CSP package, MICRO FOOT® 4 bumps 0.8 mm x 0.8 mm with 0.4 mm pitch.
