Part Number: BQ25120A Tool/software: What is the expected behavior of the device if I have a falling VIN voltage with a battery connected? I have two VIN sources that will go from 5V to 0V in ~20s and ~3s ie very slow discharge
Part Number: BQ25120A Tool/software: Hello!
Our schematic uses SYS output only. PMID and LS/LDO aren't used.
Can we remove the capacitors for PMID, LS/LDO, and VINLS pins from the schematic?
Kind regards,
L

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 Philip,
Philip Gruebele said: I am still wondering if adding a small series inductor will be a better way of permanently working around this issue. Do you have any thoughts from engineering on this?
I will look into this with design to see if that might…
Part Number: BQ25120A Other Parts Discussed in Thread: ALP Tool/software: Hey,
We are setting BUVLO to 3V but the battery keeps draining until it is empty. We tried all of the buvlo values but the battery fet does not disconnect the battery and it keeps…
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.
Philip Gruebele said: In my first "good" waveform I see about 1mV ripple and in the second waveform…
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…
