3 Description
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. The
devices also provides a low-power sleep function.
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 (OCP), short-circuit protection,
undervoltage lockout, and overtemperature.
The DRV8823 is packaged in a 48-pin HTSSOP
package (eco-friendly: RoHS and no Sb/Br).
