BTS7960B 43A H-Bridge High-Power Motor Driver Module

The BTS7960B 43A H-Bridge high-power motor driver module connects the motor between four switching transistors arranged in an H configuration — energising different transistor pairs switches current direction through the motor, reversing rotation without rewiring. The BTS7960B 43A H-bridge high-power motor driver uses two BTS7960B Infineon half-bridge ICs to form a full H-bridge rated at 43A peak and 25A continuous current across supply voltages from 6V to 27V DC. That current capacity handles motors that TB6612FNG and L298N drivers cannot drive — large brushed DC motors, high-torque gear motors, and electric vehicle wheel motors all fall within range.

The bts motor driver module path resistance of 16 mΩ at 25°C means the driver drops under 0.5V across the output stage at 25A — far lower than the L298N which drops up to 2V and dissipates significant power as heat. The integrated heatsink manages thermal dissipation during continuous high-current operation without requiring an external clip-on heatsink or forced airflow in most builds. PWM frequency at 25 kHz runs above the 20 kHz human hearing threshold, eliminating the audible motor whine that lower-frequency PWM produces.

Control signal input accepts both 3.3V and 5V logic levels, connecting directly to Arduino, ESP32, and STM32 GPIO pins without level shifting. Quiescent current at 7µA keeps standby power draw negligible in battery builds where the driver stays powered continuously between motion commands. The bts7960 H-Bridge motor driver suits heavy-duty robot drives, electric scooter controllers, and industrial automation axis builds. Available on StemVolt. This module for makers working on high-current motor control and practical heavy-duty robotics.
