3953 DC motor Driver The 3953 is a handy 1.2 amp motor driver. It is capable of driving a 30v 1 amp dc motor. February 16, 2007, at 01:11 AM

Changed lines 19-24 from:
The 3953 is a dc motor driver capable of 1.3 amps and 50 volts max. It is controlled through two wires from your microprocessor. Using a PWM signal to the phase pin the 3953 can drive a dc motor in either direction and vary the speed. Using a digital LOW enables the break. The motor is locked in it's current position while this pin is held LOW, when the pin goes HIGH the break is released and the motor continues to turn. If the break is never to be used, this pin can be tied to +5. to:
