DS2762 High-Precision Li+ Battery Monitor With Alerts
CURRENT OFFSET COMPENSATION
Current measurement and current accumulation are internally compensated for offset on a continual basis
minimizing error resulting from variations in device temperature and voltage. Additionally, a constant bias can be
used to alter any other sources of offset. This bias resides in EEPROM address 33h in two’s-complement format
and is subtracted from each current measurement. The current offset bias is applied to the internal and external
sense resistor configurations. The factory default for the current offset bias is 0.

VOLTAGE MEASUREMENT
The DS2762 continually measures the voltage between pins V IN and V SS over a 0 to 4.75V range. The voltage
register is updated in two’s-complement format every 3.4ms with a 4.88mV resolution. Voltages above the
maximum register value are reported as the maximum value. Figure 7 shows the voltage register format.

TEMPERATURE MEASUREMENT
The DS2762 uses an integrated temperature sensor to continually measure battery temperature. Temperature
measurements are placed in the temperature register every 220ms in two’s-complement format with a 0.125°C
resolution over a ± 127°C range. Figure 8 shows the temperature register format.
