3 Description

The TPS27082L IC is a high-side load switch that

integrates a Power PFET and a control circuit in a

tiny TSOT-23 package. TPS27082L requires very low

ON-state quiescent current and offers very low OFF•

state leakage thus optimizing system power

efficiency.

TPS27082L ON/OFF logic interface features

hysteresis, thus providing a robust logic interface

even under very noisy operating conditions. TPS27082L ON/OFF interface supports direct

interfacing to low voltage GPIOs down to 1 V. The

TPS27082L level shifts ON/OFF logic signal to VIN

levels without requiring an external level shifter.

TPS27082L features a novel OFF isolation circuit that

prevents PMOS from turning ON in applications that

may have fast transients, at the VIN pin when the

load switch is in the OFF-state.
