Part Number: BQ76907-Q1 Dears,
Put the voltage of one battery artificially at 0v, and the voltage of other batteries is 2.6v normally. If charging is not started, an equalization instruction is given to the normal battery, and it is found that it…
Hello Alon,
Alon Chen said: Question 1: When the voltage equalization function is active, what states are these two FETs in? How do they operate?
The cell balancing operates independently from these FETs.
Alon Chen said: Question 2: During normal…
Part Number: BQ76907-Q1 Other Parts Discussed in Thread: BQ76907 Hi TI team,
I would like to confirm whether our 4-cell battery configuration is correct when using the BQ76907.
In our design:
A 4-series cell stack (4S) is used
Could you please…
Part Number: BQ76907-Q1 Hi
I would like to understand whether BQ76907-Q1 is ASIL-D compliant . If it is, I am unable to find any explicit ASIL-D reference in the datasheet. However, in the attached image, the device appears to be shown as part of an…
Hello Chonghui,
I don't notice any issues in the code.
Chonghui Liu said: I discharged a single capacitor
How much are you discharging the one capacitor by?
Chonghui Liu said: set the equalization mask for the other four capacitors to 1.
What…
Part Number: BQ76907-Q1 Other Parts Discussed in Thread: BQ76907 Dear Team,
A customer is using the BQ76907 for supercapacitor charge management. Currently, regarding the BQ76907 chip, we have the following questions and would appreciate your confirmation…
Hello JeongWoo,
JeongWoo Hwang said: Should I consider the 50mA internal balancing as enabling simultaneous control of all cells?
This value is the rating for the internal cell balancing FET. You should also consider the temperature of the die as…
Part Number: BQ76907-Q1 Other Parts Discussed in Thread: BQ76907 Hi
Does the BQ76907-Q1 have a write-cycle limit for the Data Memory (Table 12.6) when updating it using CONFIG_UPDATE mode? Are these Data Memory settings stored in volatile or non-volatile…
Part Number: BQ76907-Q1 Other Parts Discussed in Thread: BQ76907 Hi Team, The following customer is using the BQ76907 for current detection and balancing during charging/discharging in an automotive supercapacitor AFE. Please review the schematic to verify…
Part Number: BQ76907-Q1 Hi,
I was going though the literature for cell balancing available in TRM. Cell balancing is activated and de-activated based on Min temp threshold(TS pin), Max temp threshold(TS pin) and Internal die temperature settings. We…
