Part Number: BQ24020 Hi,
We have the pin TTE connected to the ground constantly.
I found in datasheet ,when entry timer fault condition, need toggling TTE to clear the fault, if always connect to GND, may hard to recovery.
Except that, Are there…
Part Number: BQ24020 Hello,
I can't find out POR conditions in datasheet.
I am designing the charger that battery is connectd to bq24020 alltime. I want know Timer fault reset if we disconnect power to Vac and Vusb after bq24020 detected Timer fault…
Part Number: BQ24020 Hello.
I noticed that part of Figure2(page 9) is cut off in the datasheet.

Could you give…
Hi Bill,
Thanks for your reply. This is what I thought might be happening, however, the datasheet for the BQ24020 suggests that if less than 3V is detected (as would be expected in the battery protected shutdown case) the bq24020 would attempt to do…
Part Number: BQ24020 If ISET2 (pin 7) is pulled high (charging at 500 mA) and then ISET (pin 2) is left floating, will charging still work ?
Thanks in advance
Other Parts Discussed in Thread: BQ24020 What taper current I take to calculate taper rate? In the datasheet for bq24020 charger there are 2 values for the taper current, depending what USB you are using. USB500 has 50mA taper current when USB100 has…
