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 wafer level CSP package, MICRO FOOT® 4 bumps 0.8 mm x 0.8 mm with 0.4 mm pitch.
