Part Number: BQ25120A Tool/software: Hello,
I am finding figure 9-3 possibly inaccurate, and I am having difficulty understanding how the "decoder" section works.
It shows the battery voltage input as 0.8 * vbat.
and vref as vbat_request ? …
Hi Alp,
Can you confirm quiescent current into the MCU pin while it is in this state? The MR pin has an internal pull-up to BAT which is a possible path through which additional quiescent current can be pulled.
Best Regards,

Hi Philip,
Philip Gruebele said: What is the vertical scale in your images?
The images have a 10 mV / Div scale, with AC coupling. The DC value is about 1.8V.

Hi Sudheer,
The current consumption of the TS pin should be minimal since inside are only comparator input circuitry. I will have to look for an exact number.
This current flow should be fine, the TS function at this device cares mostly about the voltage…
Part Number: BQ25120A Hi,
Datasheet specify SYS-out can be disabled over I2C and only can be enabled when MRreset or valid Vin input occur.
When ı disabled Sys-out, Sys-out really goes down to 0V. In that situation ı want to read battery voltage over…
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?
