Frequently asked questions
How many battery cells can one LTC6802-1 monitor?
One device monitors up to 12 series-connected cells with an input common-mode voltage up to 60 V. Several devices can be placed in series to monitor each cell in a longer battery string.
How do multiple devices communicate with a microcontroller?
The devices use a serial interface with level shifting, so their ports can be daisy-chained without opto-couplers. A host microcontroller connects to the chain and reads the cell voltages through this serial link.
