BQ20Z655: Cell Insertion Order LED Fault Status

Mark Ackerson

Part Number: BQ20Z655

Does the BQ20Z655 have any requirements for cell insertion order or any special power up requirements? i.e. does the low voltage cell need to be inserted first? Or can cells be inserted in any order?

Also, can the LEDs be used to display any charging fault codes? i.e. charger timouts, OV, UV, OC, etc

Thanks,
Mark

Hello Mark,

Ideally, if you can attach VC1 to VSS first and the rest of the cells VC2-VC1, etc... that would be ideal, but I have not seen any issues with "random" cell connection.

LEDs cannot be used to display fault codes.
