Question: What is the limitation on the output of the 555 timer with respect to the requirements of the input of the BDW42G? Can the 555 provide enough current at 5 volts to trigger (sufficiently) the input (base) of the BDW42G?
I am using a 555 timer to generate the pwm signal and would like to drive a power Darlington transistor like the BDW42G.
The Hfe of the BDW42G is 250 for 10amp Collector Emitter
Darlington output requirements: 90volts DC at 10Amps (max)
