J11, TP10 – VBIAS

This is the VBIAS input for the device. A shorting jumper can be connected across J11 to connect the VIN of either channel to VBIAS. An external source can be applied to VBIAS by removing the jumper and connecting a supply to TP10. Please refer to the TPS22976A data sheet TPS22976 5.7-V, 6-A, 14-mΩ On-Resistance Dual-Channel Load Switch data sheet for proper VBIAS voltage level settings.
