Product Overview
The TPS22976 is a Texas Instruments dual-channel load switch for Power_Management designs that need two controlled power paths in one device. VIN1 and VIN2 operate from 0.6 V to 5.7 V, while the VBIAS recommended range is 2.5 V to 5.7 V. Each channel supports 6 A continuous switch current, with an 8 A pulsed switch-current rating for pulses below 300 us at 3% duty cycle.
The device is supplied in a DPU 14-pin WSON package with a 3.00 mm x 2.00 mm body and exposed thermal pad. Thermal data for this package includes 50.8°C/W junction-to-ambient resistance, 18.4°C/W junction-to-board resistance, and 6.5°C/W junction-to-case bottom resistance. The recommended operating ambient temperature range is -40°C to 105°C.
Control functions include ON1 and ON2 input thresholds, 90 mV typical ON-pin hysteresis, and CT1/CT2 slew-rate control pins that may be left floating. TPS22976 and TPS22976A variants include quick output discharge, while TPS22976N omits QOD.
