NO. NAME TYPE(1) DESCRIPTION
1 VDD P Power supply
2 V7 I Sense input for positive voltage of the seventh cell from the bottom of the stack
3 V6 I Sense input for positive voltage of the sixth cell from the bottom of the stack
4 V5 I Sense input for positive voltage of the fifth cell from the bottom of the stack
5 V4 I Sense input for positive voltage of the fourth cell from the bottom of the stack
6 V3 I Sense input for positive voltage of the third cell from the bottom of the stack
7 V2 I Sense input for positive voltage of the second cell from the bottom of the stack
8 V1 I Sense input for positive voltage of the first cell from the bottom of the stack
9 VSS P Electrically connected to IC ground and negative terminal of the lowest cell in the stack
10 COUT O Output drive for overvoltage, open wire, and overtemperature. It can be left floating if not used.
