BTS7960 43A High Power H-Bridge Motor Driver Module (6V-27V)

Overview

The BTS7960 is an industrial-strength, high-current dual half-bridge driver designed to control high-power DC motors up to 43A continuous peak load. Equipped with optical isolation and built-in thermal protection, this module replaces fragile low-power drivers (like L298N) for heavy university graduation project rover cars, electric wheelchairs, and high-torque automation.

Key Features

• Massive 43A Current Capacity: Dual BTS7960 semiconductor chips handle heavy starting loads without voltage sag.
• Optocoupler Signal Isolation: Protects microcontrollers (Arduino, STM32, ESP32) from inductive motor voltage spikes.
• Full PWM Control: Supports PWM speed regulation up to 25kHz for smooth, jerk-free velocity profiles.
• Heavy Aluminum Heatsink: Factory-mounted aluminum extrusion ensures optimal heat dissipation during sustained heavy runs.

Technical Specifications

• Input Voltage Range: 6V to 27V DC
• Peak Current Rating: 43A (instantaneous), 15-20A continuous
• Logic Input Level: 3.3V to 5V DC
• Protection: Thermal shutdown, overvoltage, undervoltage, and short-circuit protection.
