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

The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module is; a fully integrated high current H bridge for motor drive applications using the BTS7960 high current half bridge. the BTS7960 is part of the NovalithICTM family. This containing one p-channel high side MOSFET and one n-channel low side MOSFET; with an integrated driver IC in one package. Due to the p-channel high side switch; the need for a charge pump is eliminated thus minimizing EMI.

Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs; diagnosis with current sense, slew rate adjustment; dead time generation and protection against overtemperature, overvoltage, under voltage; overcurrent, and short circuit.
The Double BTS7960 43A H-Bridge High-Power Stepper Motor Driver Module provides; a cost-optimized solution for protected high current PWM motor drives with very low board space consumption.

Input port:

1. RPWM: forward level or PWM signal input, active high.
2. LPWM: Reverse level or PWM signal input, active high.
3. R_EN: forward drive enable input, high-level enable, low level off.
4. L_EN: Reverse drive enable input, high-level enable, low level off.
5. R_IS: forward drive current alarm output.
6. L_IS: Reverse drive current alarm output.
7. VCC: +5 V power output, 5V power supply connection with the microcontroller.
8. GND: signal common low end.
