2x7A DC Motor Driver

An ultra-compact dual DC motor driver built around a robust H-bridge design with 7 A continuous current per channel and a 50 A peak rating. Opto-coupler isolation on all control signals protects your microcontroller from motor-induced reverse currents, while built-in UVLO (Under-Voltage Latch-Out) and ESD protection keep your system safe.

The driver accepts 3.3 V and 5 V logic levels, making it compatible with Arduino, Raspberry Pi, and other popular development boards. PWM speed control is supported with a minimum valid pulse width of just 5 µs.

Key Features

• Dual Channel, 7 A Continuous – Drive two DC motors at up to 7 A each (50 A peak)
• Wide Voltage Range – 7–24 V DC supply (6.5–27 V absolute limit)
