10.1.2.1 Cell Connection Sequence

The BQ77207 device can be connected to the array of cells in any order without damaging the device.

During cell attachment, the device could detect a fault if the cells are not connected within a fault detection delay period. If this occurs, then COUT and/or DOUT could transition from inactive to active. Both COUT and DOUT can be tied to VSS or VDD to prevent any change in output state during cell attach.
