Part Number: BQ25120A Hi,
I am going to use buck converter with voltages that 1.2V to 1.8V. Drawing current is probably maximum 6-7mA.
What should do ı to keeping efficiency above %85? or it is possible to do that? Maybe selecting right inductor would…
Part Number: BQ25120A Dear Sir or Madam,
We are currently using the BQ25120A in order to manage the charge of our battery. In order to achieve it properly, we'd like to cut the charge when the battery temperature is under or above a certain voltage.…
Part Number: BQ25120A The datasheet mentions several faults that do not appear to exist in the registers listed:
SW_SYS_SHORT, LS_LDO_OCP, OVER_TEMP,
Do they exist as a bit in some status registers?
Part Number: BQ25120A What is the behavior of the charger or how will the charging process be terminated if the TE bit (Termination/Pre-Charge and I2C Address Register) is set to disabled (= 0)? Is there a rule of thumb for a general definition of the…
Part Number: BQ25120A Seeing how TS thresholds are pretty narrow, and that the top of the divider connects to VIN which in our case is USB "5V", what happens when the rail is not very good?
The USB spec allows quite a range of voltages, so won…
Part Number: BQ25120A Other Parts Discussed in Thread: BQ25120 I am working on a small USB powered device, we are trying to improve the charge time, but only if the present USB connection allows it. I am setting the input current limit(ILIM) based on the…
Other Parts Discussed in Thread: BQ25120A Hello, I'm using the bq25120A on a printed board and when the battery is reaching a certain level of discharge, around 3.3 V and under, I have I2C communication problem, and the BQ become default value 1.8 V instead…
Part Number: BQ25120A Dear TI,
I am writing this email to complain about the BQ2520A., one of our products. And we used the BQ25120A device for battery charging and monitoring along with the battery gauge (BQ27425) IC. But We are facing a problem after a…
