TPS27082L (NRND) PFET Load Switch with Adjustable Slew Rate, Fast Transient Isolation & Hysteretic Control

 

Not Recommended for New Designs (NRND)

Replaced By TPS22810 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

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.
