3 Description

The DRV8833 device provides a dual bridge motor

driver solution for toys, printers, and other 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 Hand

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, undervoltage lockout, and 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).
