SiP32454, SiP32455 www.vishay.com Vishay Siliconix 0.8 V to 2.5 V, 28 m , Slew Rate Controlled Load Switch in WCSP4 DESCRIPTION FEATURES The SiP32454 and SiP32455 are slew rate controlled Low input voltage, 0.8 V to 2.5 V integrated high side load switches that operate in the input Low R , 28 m typical ON voltage range from 0.8 V to 2.5 V. The SiP32454 and Slew rate control SiP32455 are of n-channel MOSFET switching elements Low logic control with hysteresis that provide 28 m switch on resistance. They have a 1 ms at 1.2 V and 1.5 ms at 2.5 V slow slew rate that limits th e Reverse current blocking when disabled Available in-rush current and minimizes the switching noise. These Integrated output discharge switch for SiP32454 devices low voltage logic control threshold can interface Integrated pull down resistor at EN pin with low voltage control I/O directly without extra level shift 4 bump WCSP 0.8 mm x 0.8 mm with 0.4 mm pitch or driver. A 2 MW pull-down resistor is integrated at logic package control EN pin. SiP32454 integrates a switch off output discharge circuit. Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 Both SiP32454 and SiP32455 are available in compact wafer level CSP package, WCSP4 0.8 mm x 0.8 mm with APPLICATIONS 0.4 mm pitch.
