• description

  LTC^®6803is the second generation of complete battery monitoringIC, built-in one12bitADC, a precision voltage reference, a high voltage input multiplexer, and a serial interface. eachLTC6803Ability to measure up to12The voltage of a series battery or supercapacitor.Can put several LTC6803 Devices are stacked to monitor the voltage of each cell in a long string.eachLTC6803-2/ LTC6803-4Has an individually addressable serial interface that allows up to16piece LTC6803-2/ LTC6803-4The devices are connected to a control processor and operate simultaneously. Each battery input has an associated oneMOSFETPower switch to discharge overcharged batteries.LTC6803-2Inside the battery pack is the bottom end withV^― Connected. The pins of the device are with LTC6802-2compatible, providing a drop-in upgrade.LTC6803-4Then put the bottom end of the battery pack withV^― separated, thus improving the first battery(cell 1)of measurement accuracy.
  
  LTC6803Provides a way to reduce the supply current to12μAStandby mode. furthermoreLTC6803It can also be powered from an isolated source, providing a way to reduce the current drawn by the battery pack to zero.
