DESCRIPTION The SiP32454 and SiP32455 are slew rate controlled integrated high side load switches that operate in the input voltage range from 0.8 V to 2.5 V. The SiP32454 and SiP32455 are of N-channel MOSFET switching elements that provide 28 mΩ 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 the in-rush current and minimizes the switching noise. These devices’ low voltage logic control threshold can interface with low voltage control I/O directly without extra level shift or driver. A 2 MΩ pull-down resistor is integrated at logic control EN pin. SiP32454 integrates a switch OFF output discharge circuit. Both SiP32454 and SiP32455 are available in compact wafer level CSP package， WCSP4 0.8 mm x 0.8 mm with 0.4 mm pitch.
