Short circuit collector current
SpletThe open collector internally forms either a short-circuit (technically low impedance or "low-Z") connection to ground when the transistor is switched on, or an open-circuit … SpletThe current limiting circuit consists of a transistor Q 3 and a resistor R 5 (approximately 1 ohm) connected between base and emitter terminals of transistor Q 3.With normal load current, transistor Q 3 remains off because the voltage drop across resistor R 5 is small (less than about 0.7 V necessary for making the transistor Q 3 on). Under this condition, …
