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 any risks…
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 Hi,
I am using the BQ24020 to charge a LiPO battery which has built in protection using an S-8261 based protection circuit which has overdischarge protection and cuts out at about 3V. After the battery is exhausted, I connect power…
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 only…
