Cheap Motor drivers [OT]
I'm looking for a cheap half bridge driver, perhaps a MOSFET driver,
that will take a 5 volt input signal and drive a 24 volt motor both
I discovered the Telcom semiconductor TLC4427 in an old Nuts and
Volts article, and it looked like just what I needed. Hook up
ground, two 5 volt signals, and a higher voltage (up to 22 volts, it
sez here) and you have two pins able to drive a small DC motor.
Not so fast. At 18 volts, the H-bridge shorts out and renders the IC
into a small 8-pin paperwieght. Even with a 13 volt power supply
with a lot of ripple, these things last a few seconds before they
blow, with no load. I think they are worthless at anything over 6
What do you PICsters use to drive relays and small DC motors?
