Description
170W H Bridge Motor Drive Circuit NMOS with Emergency Brake Forward Reverse Full Bridge Motor Driver Circuit
The high-power H-bridge motor drive module is composed of a single H-bridge driver IC plus four external NMOS tubes, which has low heat generation and good braking effect.
Product parameters With full bridge driver chip + low-pass internal resistance 55V110A NMOS, motor forward and reverse can be realized Two PWM inputs, the duty cycle can be adjusted within 0-100%, with instant braking capability Control is extremely simple and convenient, only need 3 input lines to control the motor The chip has built-in dead zone hardware control, which is more suitable for frequent commutation to reduce the loss of the tube itself. The back of the module is tin-plated, and the wires can flow more current to support 5V, 3.3V logic inputs. It is suitable for direct control of each type of single-chip microcomputer IO port, and can also control motor forward and reverse through analog input.
