DESCRIPTION
Independent Multicell
Battery Stack Fault Monitor
The LTC6801 is a multicell battery monitoring IC in-
corporating a 12-bit ADC, a precision voltage reference,
sampled comparator, and a high voltage input multiplexer.
The LTC6801 can monitor as many as 12 series con-
nected battery cells for overvoltage, undervoltage, and
overtemperature conditions, indicating whether the cells
are within specied parameters. The LTC6801 generates
a clock output when no fault conditions exist. Differential
clocking provides high noise immunity and ensures that
battery stack fault conditions cannot be hidden by frozen
bits or short circuit conditions.
Each LTC6801 can operate with a battery stack voltage up
to 60V and multiple LTC6801 devices can be stacked to
monitor each individual cell in a long battery string. When
multiple devices are stacked, the status signal of each
LTC6801 can be daisy-chained, without opto-couplers or
isolators, providing a single status output for the entire
battery string.
The LTC6801 is congurable by external pin strapping.
Adjustable overvoltage and undervoltage thresholds sup-
port various Li-Ion chemistries. Selectable measurement
times allow users to save power.
