description

LTC®The 6801 is a multicell battery monitoring IC that contains a 12-bit ADC, a precision independent voltage reference, sampling comparator, and a high voltage input multiplexer. The LTC6801 is capable of monitoring up to 12 cells in series packs for overvoltage, undervoltage and overtemperature conditions and indicates whether the cells are within specified parameters. When there is no fault condition, the LTC6801 generates a clock output. Differential clocks provide high noise immunity and ensure that there are no cell pack failures that die at a certain level due to the presence of a signal lock or that go undetected due to short-circuit conditions.

Each LTC6801 is capable of operating with battery pack voltages up to 60V, and multiple LTC6801 devices can be stacked to monitor each cell in a long string of series connected cells. When multiple devices are stacked, the status signal of each LTC6801 can be daisy-chained (without the use of optocouplers or optoisolators), providing a single status output for the entire battery string.

The LTC6801 is configurable with external pin strapping. Adjustable overvoltage and undervoltage thresholds support different lithium-ion battery chemistries. Selectable measurement time allows the user to save power.
