Currently i have a 3.0Volt and 0.85Amp miniature D.C Motors.
Now i planning to drive the motor using PWM method.
And the problem now is i need a Motor Controller H-Bridge. But i cant find any suitable H-Bridge Motor Controller for my motor.(as i required an DIP/PDIP or maybe SOT Pin type of H-Bridge in order to connect to the bread board ).
Does anyone have any recommandation for this type of controller?
If i am going to build the H-Bridge myself, can anyone recommanded what type of MOSFET and diode should i be getting? and how will is H-bridge circuit connection to my main microcontroller gonna be? (Currently i using a PIC18F4431 to for my microcontroller to control the motor)
Maybe a boost regulator for the micro controller and h-bridge supply, like On Semi? Lots of extra parts tho. If the 2.7V min supply is a problem then there is a TI part.
In the end, maybe take your lumps and try pinning down a tssop style package that meets your specs. Those electric toothbrushes have to run by something.
