    3 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 an 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 an 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 the

    nFAULT pin. The I2C device variant (DRV8847S) has

    detailed diagnostics.
