Description

Circuit Diagram like in Figure 1 above is Circuit Diagram Logic Controlled 12v DC Motor with Automatic Brake. According Discovercircuit site describe that there are times when you would like to control a DC motor using a simple +5v logic swing signal.  The circuit below performs this feat and also includes an automatic motor braking circuit.  When the input logic signal swings from 0v to +5v, the n-channel MOSFET Q2 turns on, which turns on the p-channel MOSFET Q1.  Current flows into the motor through the schottky diode D2.  When the control logic swings back 0v, Q1 turns off.  This activates the braking action of Q4, which applies a short across the motor.  The sudden stop is often desired in some motor controlled systems.
