H-Bridge High-Power DC Motor BTS7960 43A

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. 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.
