Transistor for driving motor with MCU
I have a similar question where i need to understand how to drive a motor circuit rated at 250ma from my PIC MCU.
First of all I cannot make out how much is the output current from the PIC.
The datasheet mentions that
Maximum output current sunk by any I/O pin........... 25 mA.
If I am driving the PIC using 3.3 V and need to drive the motor which transistor should I use to switch the motor. Also what would be the typical values for the circuit.
BEst REgards,
