Power Switch Hi Side 3A 6-Pin SOT T/R

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.
