DS2761 High-Precision Li+ Battery Monitor

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.
