Overview
The DRV8846 provides a highly-integrated stepper motor driver for cameras, printers, projectors, and other automated equipment applications. The device has two H-bridges and a microstepping indexer and is intended to drive a bipolar stepper motor. The output block of each H-bridge driver consists of N-channel and P-channel power MOSFETs configured as full H-bridges to drive the motor windings. The DRV8846 is capable of driving up to 1.4-A full-scale output current (with proper heatsinking and TA = 25°C). A simple STEP/DIR interface allows easy interfacing to controller circuits. Pins allow configuration of the motor in full-step up to 1/32-step modes. Decay mode is configurable so that AutoTune, slow decay, fast decay, and mixed decay can be used. The PWM current chopping off-time can also be selected. A low-power sleep mode is provided which shuts down internal circuitry to achieve very-low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin. Internal protection functions are provided for UVLO, overcurrent protection, short circuit protection, and overtemperature. Fault conditions are indicated via a nFAULT pin.
