Hi, I have an atmega 168 that supplies a device that should not pull much more then 100 Milli amps(should be able to measure this load soon). Normal I supply this device with USB current. however I'm forced to controller the load via 2 micro controller pins as I need to revers them for other applications. I noticed my device is pulling a bit more current that I hoped and the AVR is having trouble sustain it. I was wondering..
a) what is the max current out put of such a micro controller?
b) would using a buffer amplifier do that job, any recommendation?
