IBT-4 50A H-bridge High-power Motor Driver module/smart car

Because BTS7960/BTS7970/BTN7960/BTN7970 these chips are designed for automotive electric doors and windows, suitable for short time use, the nominal 43A current is also a short time current, this setting value for the microcontroller to provide anti-pinch function with, not suitable for long time use. The control frequency is low and the internal resistance is large. IBT-4 is not suitable for frequent adjustment of hollow cup and PID, and frequent adjustment of PWM will lead to serious heating of BTS type chip.
Provide PID program
The driver uses a full-bridge driver chip and MOSFET composed of full H-bridge drive module, with very low internal resistance and high current characteristics. MOSFET H-bridge drive circuit, with strong drive and brake effect, signal isolation chip to effectively isolate the MCU and motor drive! High current 50A!
