Part Number: BQ40Z60 Other Parts Discussed in Thread: BQSTUDIO Hi,
I've ran into a strange issue, the communication on the SMBus stops.
Situation:
The battery is part of a system when plugged into mains, the PSU charges the battery and power the system…
Part Number: BQ40Z60 Other Parts Discussed in Thread: CSD17308Q3 Hi experts
I was looking into BQ40Z60 datasheet, it mentions that the VACFET(ON) = 9V - 10V.
While the MOSFET used for ACFET in the EVM - Q5 (CSD17308Q3) has VGS maximum ratings = +10V,…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQSTUDIO I am using a custom circuit for the 3P1S Li-ion battery, and some boards fail to recognize that the power adapter has been removed. However, when the R8 (10M Ohm) value was changed to 5.1M…
Part Number: BQ40Z60 Hi,
We have BQ40z60 and we want to do some protocol to achieve regular QMAX update. But somehow our QMAX isn't update in some cycles. Did you have information about OCV flat region voltage range for Chem ID 2141 and 2144? I just want…
Part Number: BQ40Z60 Hi,
during several learning cycles i got the value 0xA in the Update Status (Adr 0x4310) after the learning cycle.
It happens when i turn of gauging (CMD 0x21). If i send the gauging CMD again the Update Status switches back to 0xe…
Part Number: BQ40Z60 Hi,
This is Jesse from Dell power design team, one question regarding to cell over voltage behavior of BQ40Z60, what's the monitor cycle to judge cell over voltage? Is it real-time/instantaneous in the detection? or it has some regular…
Part Number: BQ40Z60 Hi,
In our use case, We not able to get two DOD reading since our intensive usage. I read SLUA997 , I knew if Fast Qmax update only need one DOD0 calculation obtained from relaxed OCV reading.
In our experiment environment, we are doing…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQSTUDIO Hello
I am working on the BQ40z60 EVM. I am able to manually charge and discharge the cell. But I am still not able to configure the charging current and make it as a standalone system. Could…
Part Number: BQ40Z60 Hi TI Team,
We are using BQ40Z60 and 2 cells of Panasonic NCR18650B battery in series.
As specified in NCR18650B datasheet, the charging voltage should be 4.2+/-0.03V.
The output ripple & noise of the charger is 240mV max. The measured…
