The TPS27081A IC is a high side load switch that integrates a power PFET and a CONtrol NFET in a tiny package.

　　The TPS27081A features industry-standard ESD protection on all pins providing better ESD compatibility with other on-board components.

　　The TPS27081A level shifts ON/OFF logic signal to VIN levels and supports as low as 1.0V CPU or MCU logic to control higher voltage power supplies without requiring an external level-shifter.

　　Switching a large value output capacitor CL through a fast ON/OFF logic signal may result in an excessive inrush current. To control the load inrush current, connect a resistor R2. To further limit the inrush current add an external capacitor C1. To configure the TPS27081A to achieve a specific slew rate refer to the Application Information section.

　　A single pull-up resistor R1 is required in stand-by power switch applications that do not require inrush current control. In such applications connect the TPS27081A pin R2 to the system ground.
