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.
