Part Number: BQ76952 Tool/software: If my AFE is not connected to the battery cell and the temperature NTC, at this time, if the overvoltage fault, undervoltage fault, overtemperature protection, and undertemperature protection are correctly configured…
Part Number: BQ76952 Tool/software: Hi evryone, I am using the BQ76952 for my project of 14S battery with 150A DSG and i saw in the EVM schematics that TI used the 4.7K ohm resistor as current limitter but in my project it is not enough i would be happy…
Hello John,
John DeCesare said: Do you agree that I must connect the CELL15 and CELL3 signals? If cell 16 is lower than the other and it can't balance, then how would manually balancing them change this?
Correct, these two must be together. Because…
Part Number: BQ76952 Tool/software: Hi,
Could you please answer to following 4 questions?
(1) when operating in SLEEP mode, is it correct that the following operations are possible? ・ C-FET/D-FET on ・ MCU power is supplied from AFE REG1 ・ Current protection…
Hello,
Writing the subcommand will be the same as Figure 4-1. Captured I2C Waveform for FET_ENABLE Subcommand With CRC. Reading the data out will be the same as Figure 4-2. Captured I2C Waveform for VCell 1 Command With CRC except the read will be at the address…
Part Number: BQ76952 Tool/software: Dear Experts,
Under what other conditions than Transmit or Receive commands from Master (Host MCU) or Slave (AFE) could result in SDA line pulled low ?
What is really happening is that there is an interrupt generated…
Part Number: BQ76952 Tool/software: Hi sir,
We are using 8 CHG & 8 DSG MOSFET'S high side switching so how to decide the charge pump capacitor value & how to reduce the turn ON & OFF time of FET'S.
FET Gate capacitance is 8115pF. …
