3 Description
The DRV8833C provides a dual-bridge motor driver
solution for toys, printers, and other mechatronic
applications.
The device has two H-bridges and can drive two DC
brushed motors, a bipolar stepper motor, solenoids,
or other inductive loads.
Each H-bridge output consists of a pair of N-channel
and P-channel MOSFETs, with circuitry that regulates
the winding current. With proper PCB design, each H-
bridge of the DRV8833C can drive up to 700-mA
RMS (or DC) continuously, at 25°C with a VM supply
of 5 V. The device can support peak currents of up to
1 A per bridge. Current capability is reduced slightly
at lower VM voltages.
Internal shutdown functions with a fault output pin are
provided for overcurrent protection, short-circuit
protection, UVLO, and overtemperature. A low-power
sleep mode is also provided.
