Part Number: BQ24640 Hi
i am use BQ24640 ic to charge supercap 58F/16V. As per design iset is set 3A & O/P volt is set 8V.
if supercap voltage below 1V then the BQ ckt is not charge the supercap at set output level.
It is stop charging at 2V. If i…
Part Number: BQ24640 Hi
The customer design the schematic with BQ24640, the voltage is set 12V, abnormal output 1.7V (HIDRV=PH=1.7V, LODRV=GND=0V)
Please help check the schematic.
Thanks
