SiP32451, SiP32452, SiP32453
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.
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.
