Features:
1. Using two-way half-bridge driver chip + low-pass internal resistance 55V110A NMOS, the motor can be forward and reversed.
2. Two-way PWM input duty cycle can be adjusted within 0-99%, with instant braking ability!
3. The working voltage is 5V-30V, and the power is below 170W.
4. The control is extremely simple and convenient, only 3 input lines are needed to control the motor.
5. The chip has built-in dead zone hardware control, which can better adapt to frequent commutation and reduce the loss of the tube itself.
6. Support 5V, 3.3V logic input suitable for direct control of IO ports of various types of microcontrollers.
7. The back of the module is tinned, and the wires can flow more current.
The high-power H-bridge motor driver module is composed of two half-bridge driver ICs and four external NMOS transistors, with low heat generation and good braking effect.
Description:
1. Interface description: VIN: positive power supply;
GND: negative pole of power supply;
12V: 12V output port
MOT+, MOT-: motor output interface
EN: enable terminal, active low
IN1: logic input 1
IN2: Logic input 2
2 Instructions for use: PWM speed control air system;
IN1=PWM pulse (0-99%) ;IN2=0;forward speed adjustable;
IN1=0;IN2=PWM pulse (0-99%); reverse speed adjustable;
IN1=0;IN2=0;motor brake;
Note: After the module is powered on each time, there needs to be a falling edge before the control terminal gives 0, that is, pull it high and then pull it low. It is recommended to use a single-chip microcomputer to control it.
Due to the use of the bootstrap capacitor scheme, the PWM duty cycle cannot reach 100%, and the control terminal cannot be directly connected to 1.
