Product Overview
The TPS22975 is a Texas Instruments single-channel load switch for Power_Management designs. It operates with VIN from 0.6 V to VBIAS, VBIAS from 2.5 V to 5.7 V, ON pin voltage from 0 V to 5.7 V, and VOUT from 0 V to VIN. The device is specified for -40°C to 105°C free-air operation.
The switch path is rated to 6 A continuous current, with an 8 A pulsed switch current rating for pulses under 300 µs at 2% duty cycle. On-resistance is specified across multiple bias and input conditions, including 16 mΩ typical at VBIAS = 5 V and VIN = 0.6 V to 5 V.
The 8-pin WSON (DSG) package measures 2.00 mm × 2.00 mm and includes a thermal pad. Supporting characteristics include a recommended 1 µF input capacitor, ON input thresholds, output pulldown resistance for TPS22975, shutdown current limits, ESD ratings, and thermal shutdown with hysteresis. These parameters support power-rail load switching where bias voltage, enable thresholds, thermal limits, and output discharge behavior must be controlled.
