Hi all,
I have a problem with the L6924 in the below schematic. After ca. 1 minute of USB power both red and green LED lit and the output keeps on bouncing from 0 to 4.6V with or without battery attached. The 5V USB are stable and so is the charger output (4.196V) until it happens.
I have tried to get rid of the NTC and use aa equal value resistor (470R) as per datasheet even though the voltage at TH pin is stable at .575V
Any suggestion?
