Product Overview


The LTC6802IG-2#PBF is a multicell addressable Battery Stack Monitor 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 under-voltage 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.
