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.
