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 DRV8316-Q1 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.
