Thanks for any help. To participate you need to register. Replacement Transformer Started by ncag Today at 7: I’ll triple check the pinout again. Datasheeh it’s not, I’d very carefully check the pin connections and orientation of the ICs, a track fault or pin swap is the most likely problem.
However, the current monitors start drawing way too much current the instant power is applied. What could be going on here?

Initially, I had only the right hand side INA populated, then only the one on the left side of datasheet schematic – both show the same behaviour. Pioneer Elite vsxtx water damage no power Started by Watin Today at This would suggest that the problem only appears when pins 3 and 4 on the chip see any voltage above ground.
Welcome to our site! Datashheet must log in or register to reply here. At one point, D4 wasn’t populated yet and the left hand side INA didn’t draw too much current. There is nothing wrong with your schematic, it ties up perfectly with the INA datasheet. I tried ramping up the battery voltage through a PSU datwsheet solar panel connected and at one volt, the current draw is already about mA. So, to determine whether the IC itself is defective, tie both inputs together essentially in139 the current sensing resistor and see whether the IC repeats the anomalous behavior.
One has now disappeared in smoke. Hi everyone, I’m trying to build a solar charger, using a simple boost configuration. I checked for short circuits and everything, nothing. The battery voltage will not exceed 30 volts.
