Small DC motor driver

Category: Tag:

Linear DC motor driver for low power motors, with linear i mean it does not use PWM to drive the motor, this prevents noise. i have used this circuit over many years and found it to be useful for driving low power dc motors.
it has build in over current protection, hold current is 250ma (means the fuse is rated for 250ma), trip current is 500ma (it means the maximum current for the fuse to trip is 500ma).
the fuse is a PTC fuse, this means it will reset by cooling down. so if it trips, you can turn the pots to the left (down) wait a few seconds and turn the pot up a again.

FEATURES

– main adjust, sets the voltage. and shifts the cv input voltage up and down.
– cv input volume control, if no external voltage in is connected it sets the offset to ground for the dc motor, basically it sets the lowest point the motor starts to rotate at.
