6x PWM mode or 3x PWM mode (with or without current limit) can be used to drive three solenoid loads depending on the application.
A Brushed-DC motor can be connected to two OUTx phases to create an integrated full H-bridge configuration to drive the motor. In 6x PWM mode or 3x PWM mode, current feedback can be monitored through the SOx pins of the H-bridge when current is dissipated through that phase’s low-side FET during motor control. In 6x PWM with Current Limit or 3x PWM with Current Limit mode, cycle-by-cycle current can be implemented by setting the ILIM analog voltage to the proportional threshold.
Solenoid loads can be connected from OUTx to VM or GND to use the DRV8316C as a push-pull driver in 6x PWM or 3x PWM mode. When the load is connected from OUTx to GND, current is sourced from the high-side MOSFET and therefore current feedback or cycle-by-cycle current limit is not available. When the load is connected from OUTx to VM, current feedback or cycle-by-cycle current limit can be used depending on the mode configuration.
