BQ76952: BQ76952 VC0 VSS connection

Part Number: BQ76952

Hi

The customer design with BQ76952, VC0 on the PCB has been connected to VSS through a series resistor (the B trace marked in the figure)

The installation sequence is:

step1, point A in the figure is connected first (at this time, VSS is suspended and not connected to the negative pole of cell1)

step2, Connector J1 is inserted into PCB (power on in random order)

Does this situation meet the requirements?

Waiting for your reply.

Thanks

Star

    Hi Star,

    I do not see an issue with the connections. 

    I do have a comment on the GND of the BQ IC. Where does the GND of the IC connects to? We recommend connecting the GND of the BQ IC to BAT- (A for the design) through a NET-TIE. See below
