The TPS4H160-Q1 device is fully protected quad channel smart high-side switch with four integrated 160-mΩ NMOS power FET. The PRG0_PRU1 and GPMC signals from HSE connector is connected to MUX which routes the signals either to Test Header or to the TPS4H160-Q1. The selection is done using on board jumpers. The OUT pins from the high side switch is connected to the L+ signals of the eight M12 Connectors. The OUT pins are controlled by Enable signals coming from the Mux. SEL and SEH are two pins to multiplex the shared current-sense function among the four channels. The current sense analog output is grounded via 768Ω and is connected to the AM64x EVM board via the ADC connector 68683-310LF . A 3.33K resistor is connected to ground from the current limit pin to set the current limit threshold to 0.6A.
