DESCRIPTION
VC0, VC1, VC2, VC3, VC4,
VC5, VC6, VC7, VC8, VC9,
VC10, VC11, VC12
20, 18, 16, Battery cell voltage inputs. VCn connects to the positive terminal of CELLn and the negative terminal of
14, 12, 10, 8, CELLn+1. (VC12 connects only to the positive terminal of CELL12 and VC0 only connects with the negative
6, 4, 2, 64, 62, terminal of CELL1.)
60
CB1, CB2, CB3, CB4, CB5, 19, 17, 15, Cell balancing FET control outputs. Each output controls an external FET, which provides a current path
CB6, CB7, CB8, CB9, CB10, 13, 11, 9, 7, 5, around the cell for balancing.
CB11, CB12
3, 1, 63, 61
VBAT
58, 59 Main IC Supply pins. Connect to the most positive terminal in the battery string.
VSS
21, 22 Ground. These pins connect to the most negative terminal in the battery string.
ExT1, ExT2, ExT3, ExT4
24, 26, 28, 30 External temperature monitor or general purpose inputs. The temperature inputs are intended for use with
external resistor networks using NTC type thermistor sense elements but may also be used as general
purpose analog inputs at the user’s discretion. 0V to 2.5V input range.
TEMPREG
29
Temperature monitor voltage regulator output. This is a switched 2.5V output, which supplies a reference
voltage to external NTC thermistor circuits to provide ratiometric ADC inputs for temperature measurement.
