Part Number: BQ24272 Other Parts Discussed in Thread: BQ24160 , Hi,
Some times the charger IC oscillates between "Charging" and "In ready". I have not been able to replicate the issue - the video is from the field.
The video displays…
Jeff,
The sense resistor is only 10 mOhm (so very low burden voltage), so I guess it should not matter. The oscillation did not go away when shorting the sense resistor.
Could you emphasize what you mean by: "... then I recommend using this bit when the…
Thanks Scott,
We have a OverVoltage message from the GPRS module when the Voltage is exceeding 4.6V so that will software trigger the so called HiZ mode which is equal to a BQ power cycle (tested and is works). A very nice question why does it occurs…
Hi,
the data sheet does not clarify what "IN Ready" means. When does the charger chip enter this state?
We have seen that sometimes, after a period of charging, the IN Ready appears.
A state diagram showing all states and stimuli would be nice…
Other Parts Discussed in Thread: TPS3831 Hi,
Assuming having the below inputs:
VBAT is set to 4.0V
IBAT = 325mA
Isys = 1.25A
So Isw = IBAT+Isys=1.575A
What is the voltage Vsys – Is it VBAT + 3% -> ~4.1V
What is min VIN which can be used in…
Other Parts Discussed in Thread: BQ24272 Dear Experts,
We are using in our design BQ24272 chip for charging one cell Li-Ion battery and managing the power path for the given application.
The chip it does as expected exceping one fact:
When the battery…
