TPS27081ADDCR

The TPS27081ADDCR is a high-side Load Switch 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-V 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 and add an external capacitor C1 as shown in the Simplified Schematic. To configure the TPS27081A to achieve a specific slew rate, refer to the Application and Implementation section. A single pull-up resistor R1 is required in standby power switch applications. In such applications connect the R2 pin of the TPS27081A to the system ground when inrush current control is not required.
