TPS27081ADDCR

What is TPS27081ADDCR?

It is a high side load switch that integrates a power PFET and a control NMOS within a micro package. This device has industry-standard ESD protection on all pins, providing better ESD compatibility

with other onboard components.

It can convert the level of the on/off logic signal to VIN level and support CPU or MCU logic as low as 1.0V to control higher voltage power supplies without the need for external level shifters.

Opening a high-value output capacitor through a fast on/off logic signal may result in excessive inrush current. To control the incoming current of the load, connect a resistor R2. An external capacitor C1

can be added to further limit the inrush current. To configure TPS27081ADDCR to obtain a specific conversion rate, please refer to the Application Information section.

A standby power switch application that does not require control of inrush current requires a single pull-up resistor R1. In such applications, connect TPS27081ADDCR pin R2 to system ground.

TPS27081ADDCR Applications：

Overcurrent Protection:The device includes overcurrent protection to safeguard against excessive current flow.
