8.2.1 Primary Application

In the primary application example, the device is configured to drive a bidirectional current through an external load (such as a brushed DC motor) using an H-bridge configuration. The H-bridge polarity and duty cycle are controlled with a PWM and IO resource from the external controller to the EN/IN1 and PH/IN2 pins. The device is configured for the PH/EN control mode by tying the PMODE pin to GND.
