FWIW, I usually estimate current draw in battery backup circuits by measuring voltage on the diode that connects battery to backed-up IC. Then calculate current from diode equation. Not super precise, but more than enough to see if there's something wrong with the circuit.

This little board could be adapted to do some testing I think. I'm going to get one to look at current draw in old synth battery-backed memory designs. www.microchip.com www.microchip.com Seems to have a good range and minimal impact on the circuit under test. ______________________________ Synth-diy mailing list Synth-diy at synth-diy.org synth-diy.org synth-diy.org
