Part Number: BQ50002
Hello! I assembled the device based on the document SLVUAJ7. The device tries to start charging, then the red LED starts blinking, and then it glows constantly. Rled=24.9k.
If the resistor R18(0.02 ohm) is replaced by 0 ohm, then the charge is coming, but the LED does not signal overload. What could be wrong?

In reply to Dima Dima:
I set the voltage at pin FOD_CAL equal to 2.5 V, the product works, but the red LED does not light up. Resistors R23, 27 did not change. How correctly to make calibration? (In the description I can not understand in any way)
