Part Number: BQ76930 Other Parts Discussed in Thread: BQ76942 Hi,
We use the BQ76930 for the battery charge, and now, our end customer feedback us there are some battery are about 0V voltage,
We analyse our design, and we find our MCU is damaged but th…
Part Number: BQ76930 In BQ76930 datasheet, host MCU can send shutdown command to let BQ76930 enter SHIP mode.
After host MCU send shutdown command, how long will BQ76930 take to enter SHIP mode(REGOUT voltage drop to 0)?
Part Number: BQ76930 Hi
The customer design with BQ76930 for 20 series ternary lithium battery, reading the data from the AFE, the battery voltage of the first and eleventh strings dropped significantly.
The battery voltage of other strings only dropped…
Hi Star,
The LDO should be fine to use in theory. It may be that the external supply is initializing too slow or too late.
XREADY indicates that the device is not initializing properly and the supply not powering the pin in time could explain the fault…
Part Number: BQ76930 Other Parts Discussed in Thread: BQ78350-R1A , , MSP430FR6989 Hi,
I am considering to use the BQ76930 cell battery monitor for a configuration of parallel cells, I want to use it with the BQ78350-R1A to form a complete BMS.
I would…
Part Number: BQ76930 Hi Team,
During the use of BQ76930, if the external thermistor temperature measurement is initialized through I2C, it will cause the battery voltage sampling to jump. After shielding the temperature measurement, the voltage sampling…

Hi
The customer design with two BQ76930 cascaded for 20S, t he 6th and 7th series may be damaged during the process of plugging and unplugging cables.
The failure screen as below:
Plug in and out the cables of J2 and J3 at the icon…
Hello Shaoze,
I would imagine that you would need to calculate an offset. To calculate an offset you would need to take the voltage at two known voltage references. Then calculate the slope and see what is the offset.
This is assuming that the error in…
Part Number: BQ76930 Other Parts Discussed in Thread: SN65HVD1050 , BQ78350 Hi
My customer has questions as below.
1. BQ76930 doesn't seem to support CAN communication. Do I have to use a separate receiver to communicate with CAN?
How about using…
