This driver uses Infineon chips BTS7960 composed of high-power drive full H-bridge driver module with thermal over-current protection. Double BTS7960 H-bridge driver circuit, with a strong drive and braking, effectively isolating the microcontroller and motor driver! High-current 43A.

Specifications:

• 5V isolate with MCU, and effectively protect MCU; 5V power indicator on board.
• Voltage indication of motor driver output end; can solder heat sink.
• Just need four lines from MCU to driver module (GND. 5V. PWM1. PWM2); isolation chip 5 V power supply (can share with MCU 5 V).
• Able to reverse the motor forward, two PWM input frequency up to 25kHZ; two heat flow passing through an error signal output.
• Isolated chip 5V power supply (can be shared with the MCU 5V), can also use the on-board 5V supply; the supply voltage 5.5V to 27V.
