DESCRIPTION  
The DRV8823-Q1 device 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 through  
the serial interface) allow microstepping with bipolar stepper motors.  
Internal shutdown functions are provided for overcurrent protection, short circuit protection, undervoltage lockout  
and overtemperature.  
The DRV8823-Q1 is packaged in a 48 pin HTSSOP package (Eco-friendly: RoHS and no Sb/Br).
