The LTC6803 is a 2nd generation, complete battery monitoring IC that includes a 12-bit ADC, a precision voltage reference, a high voltage input multiplexer and a serial interface. Each LTC6803 can measure up to 12 series connected battery cells or supercapacitors. Many LTC6803 devices can be stacked to measure the voltage of each cell in a long battery string. Each LTC6803-2 has an individually addressable serial interface, allowing up to 16 LTC6803-2 devices to interface to one control processor and operate simultaneously. Each cell input has an associated MOSFET switch for discharging overcharged cells. The LTC6803-2 connects the bottom of the stack to V– internally. It is pin compatible with the LTC6802-2, providing a drop-in upgrade.
The LTC6803 provides a standby mode to reduce supply current to 12μA. Furthermore, the LTC6803 can be powered from an isolated supply, providing a technique to reduce battery stack current draw to zero.
