Hey all,
This is my first post here. I am planning to control a transistor as a heater using a microcontroller. The input to the transistor will be a 0V-3.3V PWM and I was wondering if anyone had a transistor circuit already designed. I will be using a Darlington PNP transistor, MJD117, as the heater and I know a bank of resistors will be required to divide the current that will need to be dropped through this transistor. Any design and calculations would be appreciated.
Thanks for your time,
PTGA
