DRV8847PWR General Description
The DRV8847 device is a dual H-bridge motor driver for industrial applications, home appliances, ePOS printers, and other mechatronic applications. This device can be used for driving two DC motors, a bipolar stepper motor, or other loads such as relays. A simple PWM interface allows easy interface with the controller. The DRV8847 device operates off a single power supply and 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 two full H-bridges to drive motor windings or four independent half bridges (in independent bridge interface). 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 shutting down much of the internal circuitry. Additionally, a torque scalar is provided which dynamically scales the output current through a digital input pin. This feature lets the controller decrease the current required for lower power consumption.
Internal protection functions are provided for undervoltage-lockout, overcurrent protection on each FET, short circuit protection, open-load detection, and overtemperature. Fault conditions are indicated by on the nFAULT pin. The I2C device variant (DRV8847S) has detailed diagnostics.
