TPS27081ADDCR Datasheet PDF - TI

●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.

● Adjustable turn-on and turnoff slew rate control through external R1, R2 and C1

● Supports a wide range of 1.2 to 8V supply inputs

● Integrated NMOS for PFET control

● Full ESD protection (all pins)

● Low ON-resistance, high-current PFET

● Ultralow leakage current in standby (typical 100nA)
