DESCRIPTION
The DS2761 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 DS2761 is a key component
in applications including remaining capacity estimation, safety monitoring, and battery-specific data
storage.
Through its 1-Wire interface, the DS2761 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 that allows it to be individually addressed by the host system, supporting
multibattery operation.
The DS2761 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 sense resistor or an external device. The DS2761 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 DS2761 for battery information storage: EEPROM, lockable
EEPROM, and SRAM. EEPROM memory saves important battery data in true NV 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.
