Challenges include the need for high-precision measurement of cell parameters, modular design for scalability, and ensuring reliable operation in noisy, high-temperature electrical environments.
The LTC6804 uses an isolated SPI (iso-SPI) interface that encodes signals as differential pulses and couples them via an isolation transformer to prevent high voltage from affecting other parts of the system.
The LTC6804 uses a buried zener reference voltage source instead of a bandgap reference to provide stable low drift and low temperature coefficient.
Yes, the LTC6804 directly supports passive balancing using a user-settable timer and can also be used to control active balancing.
