描述

The DRV8847 device is a dual H-bridge motor driver for industrial applications, homeappliances, ePOS printers, and other mechatronic applications. This device can be used for drivingtwo DC motors, a bipolar stepper motor, or other loads such as relays. A simple PWM interfaceallows easy interface with the controller. The DRV8847 device operates off a single power supplyand supports a wide input supply range from 2.7 to 18 V.

The output stage of the driver consists of N-channel power MOSFETs configured as twofull H-bridges to drive motor windings or four independent half bridges (in independent bridgeinterface). A fixed off time controls the peak current in the bridge which can drive a 1-A load(2-A in parallel mode with proper heat sinking, at 25°C TA).

A low-power sleep mode is provided to achieve a low quiescent current draw by shuttingdown much of the internal circuitry. Additionally, a torque scalar is provided which dynamicallyscales the output current through a digital input pin. This feature lets the controller decreasethe current required for lower power consumption.

Internal protection functions are provided for undervoltage-lockout, overcurrentprotection on each FET, short circuit protection, open-load detection, and overtemperature. Faultconditions are indicated by on the nFAULT pin. The I2C device variant(DRV8847S) has detailed diagnostics.
