DS2762
High-Precision Li+ Battery Monitor With Alerts
www.maxim-ic.com
GENERAL DESCRIPTION
The DS2762 high-precision Li+ battery monitor is a
data-acquisition, information-storage, and safety-
protection device tailored for cost-sensitive battery
pack applications. This low-power device integrates
precise
temperature,
voltage,
and
current
measurement, nonvolatile (NV) data storage, and Li+
protection into the small footprint of either a TSSOP
package or flip-chip package. The DS2762 is a key
component in applications including remaining
capacity estimation, safety monitoring, and battery-
specific data storage.

All voltages are referenced to V
SS
.
See the
Selector Guide
section to determine the corresponding part number for each V
OV
value.
Internal current-sense resistor configuration.
External current-sense resistor configuration.
Test conditions are PLS = 4.1V, V
DD
= 2.5V. Maximum current for conditions of PLS = 15V, V
DD
= 0V is 10mA.
Self-heating due to output pin loading and sense resistor power dissipation can alter the reading from ambient conditions.
Voltage offset measurement is with respect to V
OV
at +25°C.
The current register supports measurement magnitudes up to 2.56A using the internal sense resistor option and 64mV with the
external resistor option. Compensation of the internal sense resistor value for process and temperature variation can reduce the
maximum reportable magnitude to 1.9A.
Current offset error null to ±1LSB typically requires 3.5s in-system calibration by user.
Current gain error specification applies to gain error in converting the voltage difference at IS1 and IS2, and excludes any error
remaining after the DS2762 compensates for the internal sense resistor’s temperature coefficient of 3700ppm/°C to an accuracy
of
±500ppm/°C.
The DS2762 does not compensate for external sense resistor characteristics, and any error terms arising from
the use of an external sense resistor should be taken into account when calculating total current measurement error.
Typical value for t
ERR1
is specified at 3.6V and +25°C, max value is specified for 0°C to +50°C. Max value for t
ERR2
is specified
for -20°C to +70°C.
Four-year data retention at +70°C.
Typical load capacitance on
DC
and
CC
is 1000pF.
