If you have any suggestion, question, just drop a comment. See LM Spec constant current lm317. VR1 is going to be a problem as per Wouter's answer. Andy aka Andy aka k 11 11 gold badges silver badges bronze badges.

Wouter van Ooijen Wouter van Ooijen constant current lm317 I understand the heating problem. Be careful though to switch off the constant current sink when the "empty" level is reached, otherwise you may damage the battery. Measuring low ohmic resistances is done by sending a known current through the constant current lm317 resistor and measure the voltage across the resistor. This is easiest with a constant, known current, in this case 1A.

As 3 rises the Darlington transistor will turn on … … turning on the second transistor. The voltage drop across the load. Sign up to join this community. Constant current lm317 I need to worry about over voltage?

LM constant current load - Electrical Engineering Stack Exchange

Yes, that sounds fine, the cell voltages should rise as the they charge. You should be able to get a constant current lm317 rough idea of cell health by comparing their fully charged voltages, and then after letting them sit for a few hours off charge. Namespaces Article Talk.

Views Read Edit View history. The current source circuit can be easily adapted to allow us to draw a fixed current regardless of the power supplies output voltage.

Of course, we can also vary the current drawn if desired. In the example constant current lm317 shown rightwhen connected to a power supply, the circuit would draw a load of mA.

Even then, I'm looking at 2mA minimum, which is higher than the 0. Unicorn Meta Zoo 7: Interview with Nicolas. Related 5.

LM317 Constant Current Source for Lighting LEDs

Hot Network Questions.Also see LM High Power Constant Current Source Circuit. A constant current source (CCS) in electronics is a device/circuit that produces a constant value of current regardless of source voltage or load resistance. While designed as a variable voltage regulator, it will double as. In the above links I've explored using a constant current source (CCS) and basic theory. Here I'll concentrate on the use of a constant current constant current lm317 for lighting light emitting diodes or LEDs.

The value of R3 divided into volts will determine load current through each LED in.
