Product introduction :

   This driver has built-in hardware dead zone control function. The motor is safer, more stable and reliable when running forward and reverse with high current! There is also an undervoltage lockout output function! The measured continuous output is 450W (36V 15A). you get what you pay for! Welcome to test!

   This driver board can not only simulate control, but also directly accept microcontroller IO driver! This system not only can simulate control, but also has good protection functions.      

(1) Using imported full-bridge driver chip + low-pass internal resistance 110A NMOS driver tube, it can easily realize motor braking and forward and reverse rotation.

(2) The working frequency of the chip is as high as 600KHz, which can effectively solve the problem of high motor noise and heat caused by MC33886 and VNH3SP30. At the same time, the driving capability has been significantly improved and the response speed is fast. The performance of this driver is not comparable to that of L298, IR2104, MC33887 and other motor driver chips

(3) Two-way PWM input, the duty cycle can be 0-100%, which is beyond the reach of ordinary drivers. It has instant braking ability and helps you easily achieve precise control of the whole speed.

(4) It can adapt to a wider working voltage of 10.5-36V, which is suitable for robots or car model competitions directly powered by lithium batteries.

(5) Built-in logic buffer isolation circuit. Support PLC and various types of 3V or 5V single-chip IO port direct control, and can also control motor brake and forward and reverse through analog voltage input.

(6) The control is very simple, convenient and easy to use. It only needs to connect 3 input lines to control the motor braking and forward and reverse rotation.

(7) The chip has a built-in dead-time hardware control, which can effectively protect the H-bridge when the motor frequently changes direction, and avoid direct damage, so that the software programming is simpler.

(8) The working frequency of the chip is as high as 600KHZ, and it is suitable for hollow-core motor drive, with low noise and low heat generation.
