BQ77915: 00

David Yang2
Intellectual 320 points
Part Number: BQ77915

The description as below is in the datasheet

"The bq77915 device supports 3-series to 5-series cell configurations. Up to four devices can be stacked to
support ≥6-series cell configurations, providing protections up to a 20-series cell configuration. It is possible to
support greater than 20-series cell configurations, but with careful consideration of delays."

IS BQ77915 suitable for the application 26-series cells? If it be, how am I careful consideration of delays?

    Hi David,
    Each device will add a delay for the transfer of the CHG and DSG signaling. Be sure this is not significant to your application. Also check component voltage ratings for FETs and diodes, and values and currents into the LD pin(s). See figure 23 if your design will exceed the voltage range of the CHG and LD pins.
