Fixed OFF Time Control Circuit Diagram using LMD18200
Fixed OFF Time Control Circuit Diagram using LMD18200 -Using the current sensing feature of the LMD18200, the following circuit diagram appears a conventional analog control scheme called “Fixed Off Time Control”.
This circuit application is an example of Sign/Magnitude control. Whenever the motor current exceeds the desired set level a one shot is triggered which turns on the two upper switches of the H-Bridge,
shorting out the motor for a fixed time interval. By driving the direction input of the LMD18200, the motor can be reversed.
