BTS7960 43A H-Bridge DC Motor Driver Module

The BTS7960 H-Bridge DC Motor Driver Module provides high-current PWM control for DC motor projects. Built around two BTS7960 high-current half-bridge devices, it combines a compact motor-drive interface with logic-level inputs, current-sense diagnostics and integrated protection.

Key Features

• High-current H-bridge design: Two BTS7960 half-bridge devices form a full H-bridge for DC motor drive applications.
• 5.5–27V motor supply: Supports the supply-voltage range stated for this module.
• PWM control up to 25kHz: Includes active freewheeling for PWM motor-drive operation.
• Microcontroller interface: Logic-level inputs simplify connection to a suitable controller.
• Current-sense diagnostics: Status-flag diagnosis and current-sense capability help monitor driver operation.
• Integrated protection: Overtemperature shutdown with latch behaviour, overvoltage lockout, undervoltage shutdown, overcurrent and short-circuit protection.
• Onboard indication: Includes a 5V power indicator.

Technical Details

• Driver family: BTS7960 / BTS7960B, NovalithIC.
• Configuration: Two high-current half bridges forming one H-bridge.
• Supply voltage: 5.5–27V.
• Typical current-limitation level: 43A.
• PWM frequency capability: Up to 25kHz.
• Typical path resistance: 16 mΩ at 25°C.
• Typical quiescent current: 7µA at 25°C.
• Integrated functions: Dead-time generation and adjustable slew rates for EMI optimisation.
• Each driver device integrates a P-channel high-side MOSFET, an N-channel low-side MOSFET and driver circuitry. The P-channel high-side design eliminates the need for a charge pump, helping reduce EMI.
• Switched-mode current limitation helps reduce power dissipation during overcurrent conditions.

Plan Your Motor-Control Build

Use this module as the power-driver stage between a suitable controller and a DC motor. Before connecting your project, verify the module pinout, logic requirements, motor starting and stall current, wiring and cooling arrangements.

Current-rating note: The 43A figure is the stated typical current-limitation level, not a guaranteed continuous operating current for the assembled module. Select the operating load according to the module's thermal limits and your cooling arrangement. Protection features do not replace correct wiring and load selection.
