Other Parts Discussed in Thread: BQ24103

Hi

Our board uses BQ24103 according to the reference design. When no battery is connected STAT1 is blinking constantly with fixed frequency.

Why is not his output low constantly?

    More testings shows that with supply voltage of 10V STAT1 operates as expected with 11V input voltage the problem occurs.

    The data sheet states max 16V input voltage. Why does the input voltage affect the STAT1 pint output?
