However, the current monitors start drawing way too much current the instant power is applied. To participate you need to register.

INA139 current monitor draws too much current

Odysseas Member Oct 21, Click here to register now. Try to keep front and back photos the same size. At one point, D4 wasn’t populated yet and the left hand side INA didn’t draw too much current. Thread starter Odysseas Start date Oct 21, What could be going on here? To sense the current coming from the solar panel and going into the battery, I use two INA current monitor chips. You must log in or register to reply here. Not even a single miliamp. Hi everyone, I’m trying to build a solar charger, using a simple boost configuration.

So, to determine whether the IC itself is defective, tie both inputs together essentially shorting the current sensing resistor and see whether the IC repeats the anomalous behavior.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Initially, I had only the right hand side INA populated, then only the one on the left side of the schematic – both show the same behaviour.

I tried ramping up the battery voltage through a PSU no solar panel connected datasheey at one volt, the current draw is already about mA. I’ll triple check the pinout again.
