Part Number: BQ76952

Tool/software:

Hello,

What is the anticipated turn-off delay when using the improved turn-off delay circuit referenced in the app note "Multiple FETs with the BQ76952, BQ76942 Battery Monitors"?

Can you also confirm that the components circled in yellow are included to protect against reverse voltage on the pack output?

    Hello Jessica,

    I believe Figure 8-16. DSG On, 12 FETs, 10kΩ, PNP, 470nF and Figure 8-17. DSG Off, 12 FETs, R41, 1kΩ, PNP from that application note, shows the DSG on and off times.

    Correct. Please refer to Section 3 Reverse Charge Component Selection of the application note for a more detailed explanation.

    Best Regards,
