Description:
The BTS7960 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 NovalithI CTM family. BTS7960 Driver Module contains 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 Driver Module provides a cost-optimized solution for protected high-current PWM motor drives with very low board space consumption.
Note: HW-039 on board working remains the same.
