The dual BTS7960 H-bridge driver circuit has powerful driving and braking functions, effectively isolating the microcontroller and motor driver with 5V isolation, and supports high current 43A as well as motor driver output end voltage indication.
5V isolation from the single chip can effectively safeguard the single chip; the isolated chip uses 5V power supply (sharable with MCU 5V or using on-board 5V) and the board is equipped with a 5V power indicator.
The product is featured with stable performance and long service life, and its supply voltage ranges from 5.5V to 27V.
This product can realize forward and reverse rotation of the motor, and the two PWM inputs have a maximum frequency of 25kHZ; only four lines (GND, 5V, PWM1, PWM2) are needed from MCU to the driver module.
The driver uses the BTS7960 chip, which consists of a high-power drive full H-bridge driver module with thermal overcurrent protection; it can solder a heat sink and has two heat flow error signal outputs.
