If the drive pins of the AFE DSG and CHG are output, will the output of more than 1 mA for a long time cause problems? This is our drive circuit, and the measurement found that the DSG and CHG voltages are 6.7v when working
Part Number: BQ76940 Other Parts Discussed in Thread: TIDA-010030 Hi, I am an electrical power engineering student and I am using Bq76940 in my graduation project. I was investigating the datasheet and I found the you wrote this about the voltage difference…
Part Number: BQ76940 Hi TI team,
I was curious as to what happens to the internal registers of the device when it enters into SHIP mode.
The scenario I am curious about is as such:
1. The device senses OV and sets CHG_ON to 0 in response.
2. The microcontroller…
Part Number: BQ76940 Hi E2E:
The customer is designing a new product using BQ7694003.
At present, the simulation test is conducted with 15 batteries supplying 20V.
The BQ7694003 will pull down the SDA pin (probabilistic) when the Jlink reburning program…
Part Number: BQ76940 Dear Expert
The bit in the specification book is only used to control the collection of temperature and voltage. Previously, when there were current fluctuations, disable this bit during equalization, and enable this bit when reading…
Part Number: BQ76940 Dears,
My customer found SCD of some chips is always '1' when reset. For these chips, they need write '0' to clear the alert manually and the SCD will not be triggered again.
Thus, customer is considering if the bq76940…

Part Number: BQ76940 Dear Sir
The recent test found that when BMS is below -10 ℃, (it is no problem for the temperature to recover above 0 degrees) after AFE enters Shutdown Mode and wakes up through TS1 pin, MCU cannot initialize AFE successfully, resulting…
