current, temperature and voltage in independent  
32-bit registers  
Pin Summary  
Pin Name  
Description  
• 512-byte nonvolatile EEPROM stores factory  
programmed, measured and user-defined  
parameters  
VC2/IO1  
Cell voltage input for cell 2 in a  
2-series Li Ion pack or general  
purpose I/O #1  
• In-system offset calibration compensates for  
offset error in current measurement  
• Industry standard SMBus/I2C™ compatible 2-wire  
communications interface

NTC/IO0  
Oscillator bias resistor  
• 8-pin TSSOP package  
External thermistor connection or  
general purpose I/O #0  
• -20°C to +85°C operating temperature range  
• NTC pin can be configured as a thermistor input  
or GPIO  
GND  
SR  
Power supply ground  
Sense resistor input  
• VC2 pin can be configured as a cell input or a  
GPIO  
• Flexible power operating modes allow low-power  
monitoring of battery conditions during system full  
operating and standby conditions:  
- Run: Continuous Conversion; 80 µA typ.  
- Sample: Sample interval from  
0.5-64s @ 45 µA typ.  
- Sample-Sleep: Sample interval from  
0.5-138s min. @ 20 µA typ.  
• Shelf-Sleep mode reduces power consumption  
during pack storage conditions to 300 nA typ.,  
with automatic wake-up upon pack insertion
