Hi everybody:
I have implemented the circuit found in the following link:
http://www.robotroom.com/HBridge.html
for the motor I am using a linear actuator which involves a dc motor rated at 12 vdc. When the linear actuator is functioning, it does not seem to operate fast enough having no load on the actuator (about 1 amp).
The TC4424 gets very hot after a couple of seconds of the linear actuator operation and i have to disconnected immediately to prevent the chip from damaging. This does not seem to be right since the chip is being operated at 1 amp and it is rated to be capable to operate to a mamximum of 3 amps. Does anybody know why is this happening?
I think the chip should be operating normaly since the actuator is draw such a small current ?
