DESCRIPTION/ORDERING INFORMATION
The DRV8823 provides an integrated motor driver solution for printers and other office automation equipment
applications.
The motor driver circuit includes four H-bridge drivers. Each of the motor driver blocks employ N-channel power
MOSFETs configured as an H-bridge to drive the motor windings.
A simple serial interface allows control of all functions of the motor driver with only a few digital signals. A
low-power sleep function is also provided.
The motor drivers provide PWM current control capability. The current is programmable, based on an externally
supplied reference voltage and an external current sense resistor. In addition, eight current levels (set via the
serial interface) allow microstepping with bipolar stepper motors.
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage
lockout and overtemperature.
The DRV8823 is packaged in a 48 pin HTSSOP package (Eco-friendly : RoHS & no Sb/Br).
