Hi,

I searched the web for a simple constant current circuit so
I can charge a 19V rechargeable "power pack" that contains NMH cells
after they "run down" using a timer. My DC source will be 24V.

The simple circuits I found are for lighting LEDs, anything
requiring more current involves complex circuitry.

Does anyone know of a device like a simple 3 lead voltage
regulator, but for current, or a simple circuit?

Thank You in advance, John

PS, Remove "ine" from my email address if you have an image file.

Look in some of the older[20+years] application books from such as
National. The had ckts using voltage regulators as constant current
sources.
