DESCRIPTION

The DS2760 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 data storage, and Li+ protection into

the small footprint of either a TSSOP package or flip chip. The DS2760 is a key component in

applications including remaining capacity estimation, safety monitoring, and battery-specific data storage.

Via its 1-Wire interface, the DS2760 gives the host system read/write access to status and control

registers, instrumentation registers, and general purpose data storage. Each device has a unique factory-

programmed 64-bit net address which allows it to be individually addressed by the host system,

supporting multi-battery operation.

The DS2760 is capable of performing temperature, voltage and current measurement to a resolution

sufficient to support process monitoring applications such as battery charge control, remaining capacity

estimation, and safety monitoring. Temperature is measured using an on-chip sensor, eliminating the need

for a separate thermistor. Bidirectional current measurement and accumulation are accomplished using

either an internal 25m

W sense resistor or an external device. The DS2760 also features a programmable

I/O pin that allows the host system to sense and control other electronics in the pack, including switches,

vibration motors, speakers and LEDs.

Three types of memory are provided on the DS2760 for battery information storage: EEPROM, lockable

EEPROM and SRAM. EEPROM memory saves important battery data in true nonvolatile memory that

is unaffected by severe battery depletion, accidental shorts or ESD events. Lockable EEPROM becomes

ROM when locked to provide additional security for unchanging battery data.

SRAM provides

inexpensive storage for temporary data.
