8 Detailed Description
8.1 Overview
The DRV8834 supports two configurations: phase/enable mode, where the outputs are controlled by phase
(direction) and enable signals for each H-bridge, and indexer mode, which allow control of a stepper motor using
simple step and direction inputs.
DC motors can only be controlled in phase/enable mode; indexer mode is not applicable to DC motors.
Stepper motors can be controlled using either phase/enable load, or indexer mode.
The device is configured to be controlled either way using CONFIG pin. Logic HIGH on the CONFIG pin puts the
device in the STEP/DIR mode; logic LOW lets the motor to be controlled using the xPHASE/xENBL pins.
The state of the CONFIG pin is latched at power up, and also whenever exiting sleep mode. CONFIG has an
internal pulldown resistor.
