7 Detailed Description
7.1 Overview
The DRV8835 is an integrated motor-driver solution used for brushed motor control. The device integrates two
H-bridges, and drives two DC motor or one stepper motor. The output driver block for each H-bridge consists of
N-channel power MOSFETs. An internal charge pump generates the gate drive voltages. Protection features
include overcurrent protection, short circuit protection, undervoltage lockout, and overtemperature protection.
The bridges connect in parallel for additional current capability.
The DRV8835 allows separation of the motor voltage and logic voltage if desired. If VM and VCC are less than
7 V, the two voltages can be connected.
The mode pin allow selection of either a PHASE/ENABLE or IN/IN interface.
