3 Description
The DRV8849 is a dual stepper motor driver for
industrial and consumer applications. The device is
fully integrated with four N-channel power MOSFET
H-bridge drivers, one microstepping indexer for
each stepper, and integrated current sensing. The
DRV8849 is capable of driving up to 1.5-A full-scale
output current (dependent on PCB design).
The DRV8849 uses an internal current sense
architecture to eliminate the need for four external
power sense resistors, saving PCB area and system
cost. The device uses an internal PWM current
regulation scheme with smart tune decay mode.
Smart tune automatically adjusts for desired current
regulation, compensates for motor variation and aging
effects and reduces audible noise and vibration from
the motor.
Simple STEP/DIR interfaces allow an external
controller to manage the direction and step rate of
the stepper motors. The device can be configured
in full-step to 1/256 microstepping. A low-power
sleep mode is provided using a dedicated nSLEEP
pin. Protection features are provided for supply
undervoltage, charge pump faults, overcurrent, short
circuits, and overtemperature. Fault conditions are
indicated by one nFAULT pin for each stepper.
