Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module

Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module

The Double BTS7960 43A H-Bridge Motor Driver Module is a robust, high-power motor driver ideal for driving large DC motors or stepper motors in demanding applications. Built around two BTS7960 half-bridge chips from the NovalithIC™ family, it integrates a p-channel high-side MOSFET, an n-channel low-side MOSFET, and a driver IC into a single package.

Thanks to its high-current capability (up to 43A), integrated protection features, and PWM support up to 25kHz, this module is perfect for high-performance robotics, automation systems, electric vehicles, and industrial control.

With built-in logic-level inputs, current sensing, temperature and overcurrent protection, this driver ensures reliability and efficiency even under heavy loads. The absence of a charge pump (due to the p-channel MOSFET) helps reduce EMI and simplify the design.

Key Features:

• High current output: up to 43A

• Supports PWM frequency up to 25kHz

• Switched-mode current limitation reduces power loss in overcurrent conditions

• Integrated current sensing and diagnostic status flags

• Over-temperature protection with latch behavior

• Overvoltage and undervoltage lockout

• Short circuit protection

• Logic-level compatible inputs (can interface directly with microcontrollers like Arduino)

• Adjustable slew rate for EMI optimization

• Built-in 74AHC244 Schmitt-trigger octal buffer for input protection

• Dual H-bridge output allows for bidirectional motor control

Input Port Functions:

• RPWM – Forward direction PWM or HIGH logic signal input

• LPWM – Reverse direction PWM or HIGH logic signal input

• R_EN – Forward drive enable (HIGH = enabled)
