Hello, this little chip won't do as I tell it. Tried two times now, powered by 9v (open cirquit) cellphone charger. It is the version with the temp sens. The reference pin should be within 30-60% of Vcc. If there was an error there it should be flashing, which it doesnt, but it did when I used a 12v (o.c.) wart, which should be ok. I was using 10uF cer. caps but then put a large el.lyte (47uF 40v) on the input in addition.
The led shows it should be charging, but the cell stays at 3.98v.
The pcb gets quite hot, (and I tried heating it more to see if the ptc would kick in and shut it down, but no...), which could be the LED.
