H-Bridge Circuits

Alternating CW & CCW Motor Driver  -  A while back a company needed a motor controller for a custom door latching system.  The system used a small brush motor with a speed reduction gear to both latch and unlatch the door.  When pulsed for about 250ms in the clockwise direction, the motor would unlatch the door . . . [Circuit by David Johnson P.E.,  09/05/10]


Control both Power & Direction of a DC Motor  -  TTL type Q and inverted Q inputs control a classic H-bridge circuit, rated at 50 volts and about 10 Amps.  The circuit can control power and direction of a DC motor . . . [Hobby Circuit designed by David Johnson P.E.,  02/04/07]
