Hi there,
I was wondering if anyone could try to explain to me, why the Vcc in my circuit is not doing anything here. Whatever voltage I use, the only thing changing the motor voltage drop is the base voltage. Why doesn't the transistor module not work as regular darlingtons (controlling current through collector-emitter as a function of the applied base current). I'm using transistor modules MG100G2YL1, but I can unfortunately only find a datasheet for an equivalent component. That may however not be the main problem. The important data are around
hFE = 100-200
VCEsat = 2.5 V
VEBO = 7 V
The attached circuit test uses only a single transistor of the half-bridge component. I'm using a dual channel power supply, and as long as the Vcc/Vss cables are connected to channel 1 the motor runs, no matter the voltage. Can anyone help?
