Internal Protection Structure
The LTC6801 incorporates a number of protective struc-
tures, including parasitic diodes, Zener-like overvoltage
suppressors, and other internal features that provide
protection against ESD and certain overstress conditions
that could arise in practice. Figure 6 shows a simplied
internal schematic that indicates the signicant protective
structures and their connectivity. The various diodes indi-
cate the approximate current versus voltage characteristics
that are intrinsic to the part, which is useful in analyzing
responses to certain external stresses, such as during a
hot-start scenario.
SELF TEST CIRCUITRY
The LTC6801 has internal circuitry that performs a periodic
self test of all measurement functions. The LTC6801 self
test circuitry is intended to prevent undetectable failure
modes. Accuracy and functionality of the voltage refer-
ence and comparator are veried, as well as functionality
of the high voltage multiplexer and ADC decimation lter.
Additionally, open connections on the cell input pins C1
to C11 are detected (Open connections on V– or C12/V+
will cause an undervoltage failure during the normal
measurement cycle).
