Oct 23, 2023 · From 5V? That allows you to only drop 0.5V in the current limiter. See if you can get lucky and find a LDO regulator with adjustable voltage AND current limit. If you can relax the input …

Jan 29, 2018 · One very simplistic device (constant current sink with exactly two pins, designed for voltages <= 50 V and a max/constant current of 350 mA) is the NSI50350AD.

As i understand, using this circuit: Will cause the current to go right through the POT and resistor, which will generate a lot of heat. Is there a better way to use current limiting with LM317 wit...

The three new circuits are voltage regulators with a current-limiting feature. Note that if you eliminate the lower transistor and the reference diode from the third circuit, it's essentially identical to your original …

Dec 7, 2023 · Here the circuit starts limit current at about 200mV on shunt (not 600mV as standard limiter) because 400mV across BE is always presented from R2/R4 divider.

Jan 3, 2022 · Current limiting circuit: The simplest and a robust solution is to use headlight lamps as power resistors. A more elegant option is to use sensing resistors (0.6~0.7V of voltage drop at max. …

May 20, 2021 · Current limiter using 2 bipolar junction transistors (BJTs) Ask Question Asked 4 years, 7 months ago Modified 4 years, 7 months ago

Jan 2, 2022 · Here is a much better 2-transistor current limit circuit. As with all simple limiter circuits, the output voltage will decrease slightly until the current limit is reached. In this case, the output voltage …

Jun 9, 2024 · Since the goal here is to limit the inrush current, I thought to myself, why not using a proper inrush current limiter to do the same job as the pre-charge circuit. Through some research, I …

This current limiter seems pretty imprecise. I think the way to calculate the short circuit current limit is to realize that when the load is shorted, T2 is on, so T1 emitter is at 0.7V (T2 Vbe).
