Double BTS7960B DC 43A Motor Driver _-Bridge PWM (MD0012)

Key Specifications:

• Motor Supply Voltage: 6V – 27V DC (or 5.5V-27V).
• Logic Supply Voltage: 5V (isolated from MCU).
• Max Continuous Output Current: 43A.
• Peak Output Current: Up to 80A (short duration).
• Control Inputs: 3.3V – 5V logic level (PWM or Level).
• PWM Frequency: Up to 25 kHz.
• Control: Dual-channel H-bridge for forward/reverse/brake.
• Features:
  • MCU Isolation (5V chip).
  • Current Sense & Status Flags.
  • Thermal Protection (Overtemperature Shutdown).
  • Voltage Protection (Undervoltage Lockout, Overvoltage).
  • Integrated Heatsinks.
• Board Size: Approx. 40x50mm.

How it Works:

It uses two BTS7960B ICs, each forming an H-bridge, allowing control of two separate motors or one motor in both directions with speed control via PWM signals from a microcontroller like Arduino, protecting the MCU with its isolation.
