Two logic inputs control the Hbridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6-A peak current. The inputs can be pulsewidth modulated (PWM) to control motor speed, using a choice of current-decay modes. Setting both inputs low enters a low-power sleep mode. The DRV8872 device features integrated current regulation, based on an internal reference voltage and the voltage on pin ISEN, which is proportional to motor current through an ...
