Motor Driver HBRIDGE BTS7960 43A
This driver uses BTS7960B chip that is composed of high power H-bridge driver module having thermal over-current protection.
Basically it contains one p-channel high side MOSFET and one N-CHANNEL low side MOSFET with an integrated driver IC in one package.
Due to strong braking and drive in this circuit successfully isolate microcontroller and motor driver with high current i.e.43Ampere.
It’s a fully integrated high current module with
Operating Voltage of 24V
Continuous current of 43A Max
PWM capability of up to 25 kHz.
BTS7960 IC has good power protection. 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 over temperature, overvoltage, under voltage, over current and short circuit .The BTS 7960 is protected against over temperature by an integrated temperature sensor which further leads to shut down of both O/P stages.
