3 Description

The DRV8833 device provides a dual bridge motor
driver solution
mechatronic applications.
The device has two H-bridge drivers, and can drive
two DC brush motors, a bipolar stepper motor,
solenoids, or other inductive loads.
The output driver block of each H-bridge consists of
N-channel power MOSFETs configured as an H-
bridge to drive the motor windings. Each H-bridge
includes circuitry to regulate or limit the winding
current.
Internal shutdown functions with a fault output pin are
provided for overcurrent protection, short-circuit
protection,
overtemperature. A low-power sleep mode is also
provided.
The DRV8833 is packaged in a 16-pin WQFN
package with PowerPAD™ (Eco-friendly: RoHS & no
Sb/Br).
