SIP32441DNP-T1-GE4

The SiP32441 is an integrated slew rate control load switch operates in the voltage range of 1.7 V to 5.5 V. The integrated charge pump drivers enable the part with low on resistance over the wide input voltage range. Its VIN can tolerate over -2 V without causing damage or device malfunction.

The SiP32441 features a controlled soft-on slew rate of typical 2.5 ms that limits the inrush current for designs of heavy capacitive load and minimizes the resulting voltage droop at the power rails.

The SiP32441 integrated a special logic circuit to define the status of the power switch. This is to meet system design of both removable and embedded types.

The SiP32441 has exceptionally low shutdown current and provides reverse blocking to prevent high current flowing into the power source when the switch is off or VIN is ground. The switch blocks the current flow at both forward and reverse directions at off state. When VIN and EN are OPEN, the switch will remains OFF in case voltage is applied on OUT pin.

This device is specified to operate over the industrial temperature range of -40 °C to +85 °C.
