Product Detailed Description for LTC6802-2

The LTC6802-2 is a complete battery monitoring IC that includes a 12-bit ADC, a precision voltage reference, a high voltage input multiplexer and a serial interface. Each LTC6802-2 can measure 12 series connected battery cells, with a total input voltage up to 60V. The voltage on all 12 input channels can be measured within 13ms.

Many LTC6802-2 devices can be stacked to measure the voltage of each cell in a long battery string. Each LTC6802-2 has an individually addressable serial interface, allowing up to 16 LTC6802-2 devices to interface to one control processor and operate simultaneously.

To minimize power, the LTC6802-2 offers a measure mode to monitor each cell for overvoltage and undervoltage conditions. A standby mode is also provided to reduce supply current to 50µA.

Each cell input has an associated MOSFET switch that can discharge any overcharged cell.

The related LTC6802-1 offers a serial interface that allows the serial ports of multiple LTC6802-1 devices to be daisy chained without opto-couplers or isolators.

SPI Interface Features
LTC6802-1 Daisy Chain Multiple devices can be connected in serial fashion without digital isolation.
LTC6802-2 Addressable Parallel addressed SPI interface - each device in a chain communicates with a control processor in parallel via external digital isolators.

Applications
