DS2780 Standalone Fuel Gauge IC
Figure 1. Block Diagram
DETAILED DESCRIPTION
The DS2780 operates directly from 2.5V to 4.5V and supports single cell Lithium-ion battery packs. As shown in
Figure 2, the DS2780 accommodates multicell applications by adding a voltage regulator for VDD and voltage
divider for VIN. Nonvolatile storage is provided for cell compensation and application parameters. Host side
development of fuel-gauging algorithms is eliminated. On-chip algorithms and convenient status reporting of
operating conditions reduce the serial polling required of the host processor. For 2-cell applications, the DS2781 is
recommended, since it includes a voltage regulator and accepts VIN up to 10V.
Additionally, 16 bytes of EEPROM memory are made available for the exclusive use of the host system and/or
pack manufacturer. The additional EEPROM memory can be used to facilitate battery lot and date tracking and
non-volatile storage of system or battery usage statistics.
A Dallas 1-Wire interface provides serial communication at the standard 16kbps or overdrive 140kbps speeds. It
allows access to data registers, control registers and user memory. A unique, factory programmed 64-bit
registration number (8-bit family code + 48-bit serial number + 8-bit CRC) assures that no two parts are alike and
enables absolute traceability. The Dallas 1-Wire interface on the DS2780 supports multidrop capability so that
multiple slave devices may be addressed with a single pin.
