TPS27081ADDCR

Description

The TPS27081A is a high-side load switch with a Power PFET and a Control NFET integrated in a small package. The TPS27081A incorporates industry-standard ESD protection on all pins, enhancing ESD compatibility with other onboard components. The TPS27081A level shifts ON/OFF logic signals to VIN levels and supports CPU or MCU logic as low as 1-V to manage higher voltage power sources without the need for an external level-shifter. Using a quick ON/OFF logic signal to switch a large value output capacitor CL may result in an excessive inrush current. Connect a resistor R2 and an external capacitor C1 as illustrated in the Simplified Schematic to manage the load inrush current.

Refer to the Application and Implementation section to configure the TPS27081A to obtain a specific slew rate. In standby power switch applications, a single pullup resistor R1 is required. When inrush current regulation is not required, connect the R2 pin of the TPS27081A to system ground in such situations.
