DRV8833 Driver Module 2 Channel DC Stepping Motor CJMCU-8833 Control Module H-Bridge Driving Board 2.7-10.8V

DRV8833 provides a dual-channel bridge motor driver solution for toys, printers and other mechatronics applications. The device has two H-bridge drivers and can drive two direct current (DC) brush motors, a bipolar step motor, solenoids or other inductive loads. The output driver module of each H-bridge consists of N-channel power MOSFETs. These N/IOSFETs are configured as an H-bridge to drive the motor windings. Each H-bridge includes circuits for regulating or limiting the winding current. With the correct PCB design, each H-bridge of the DRV8833 can continuously provide up to 1.5-ARMS (or DC) drive current (at 25°C and using a 5WM power supply). Each H-bridge can support peak currents up to 2A. Under lower VM voltage conditions, the current supply capacity slightly decreased. The device provides an internal shutdown function implemented with a fault output pin for: overcurrent protection, short circuit protection, undervoltage lockout and overheating. In addition, a low-power sleep mode is also provided.

Instructions for use

Each H-bridge has two digital inputs (half of each bridge). You can use the PWM input to control the motor speed and run at 2.7V-10.8V logic/motor power. The motor voltage is the same as the logic voltage.
