SiP32451, SiP32452, SiP32453 www.vishay.com Vishay Siliconix 0.9 V to 2.5 V, 55 m Load Switch in WCSP4 DESCRIPTION FEATURES SiP32451, SiP32452, and SiP32453 are n-channel Low input voltage, 0.9 V to 2.5 V integrated high side load switches that operate from 0.9 V to Low R , 55 m typical ON 2.5 V input voltage range. Fast turn on time SiP32451, SiP32452, and SiP32453 have low input logic Low logic control with hysteresis control threshold that can interface with low voltage control Reverse current blocking when disabled Available GPIO directly without extra level shift or driver. There is a pull down at this EN logic control pin. Integrated pull down at EN pin Turn on time is fast, less than 25 s typically for input Output discharge (SiP32451) voltage of 1.2 V or higher. SiP32451 and SiP32452 have 4 bump WCSP 0.8 mm x 0.8 mm with 0.4 mm pitch fast turn off delay time of less than 1 s while SiP32453 package features a guaranteed turn off delay of greater than 30 s, Material categorization: for definitions of compliance typically 90 s. please see www.vishay.com/doc 99912 SiP32451 features an output discharge for fast turn off. SiP32451, SiP32452, and SiP32453 are available in compac t APPLICATIONS wafer level CSP package, WCSP4 0.8 mm x 0.8 mm with Battery operated devices 0.4 mm pitch.
