Hi Juan,
Thanks for your help regarding the VINDPM threshold. Lowering the threshold solved the issue I was experiencing.
However, I noticed a voltage drop across diode D201: I'm measuring 5.1V before D201 and 4.6V on the load side after it. I believe…
Part Number: BQ25125
Tool/software:
Due to space constraints I have to use a very small SMD inductor on the SW pin.
The datasheet recommends to use a 2.2µH inductor but these are not available in sizes smaller than 0603.
I found a small 1.5µH inductor…
Part Number: BQ25125
Tool/software:
The FAQ post says PGND and GND need to be tied together.
Also the BQ25125 Schematic Checklist mentions "Ensure USBGND and PGND are tied together." which I think is an error (there is no USBGND) and means GND.…
Part Number: BQ25125 Tool/software: I want to use Vsys with 1.8V and LDO with 1.8V which seems to be the default setting for BQ25125 as written in the device comparison table in the datasheet.
I have some questions:
1. The typical application example…
Part Number: BQ25125 Tool/software: I may be missing something - BUT...
In table 9-1 the x4 states of the device which depend on the CD input and Vin are documented.
But - in order to know which state I am in - I need to know if Vin > Vuvlo.
I obviously…
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 ? …
Part Number: BQ25125 Tool/software: We are currently designing a layout using the BQ25125 to charge a Li-Ion battery and power our product with 1.8V. We have some questions regarding pin protection.
The IN, GND, and /MR pins are accessible from outside…
Part Number: BQ25125 Tool/software: I have a BQ25125 with a status (reg 0) of 0xC9
and a fault register (1) of 0x20
I read this as a BAT_UVLO fault.
which I can see is true Vbat = 3.15 volts
However - I cannot seem to get it to "pre-charge" and recover…
Part Number: BQ25125 Tool/software: I need to out 2.5V from LS/LDO output pin
first i pulled down LSCTRL pin then i programmed the LS/LDO control register bits to make it out 1.7V and according the equation , it will be added to .8V , so the register…
Part Number: BQ25125 Tool/software: Hello,
I am experiencing an issue with the bq25125 battery charger IC. When I set the charge current (ICHRG) higher than 70mA, I receive an error status with STAT_0 and STAT_1 both set to 1 (binary 11). At 70mA, the…
