SIP32452 Datasheet, PDF (1/10 Pages) Vishay Siliconix – 1 V, 55 m Ohm Load Switch in MICRO FOOT

SiP32452, SiP32453
Vishay Siliconix
1 V, 55 m Load Switch in MICRO FOOT^®
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.
