LTC6803-1/LTC6803-3
APPLICATIONS INFORMATION
ADDING CALIBRATION AND FULL-STACK
MEASUREMENTS
The general purpose V TEMP ADC inputs may be used to digi-
tize any signals from 0V to 4V with accuracy corresponding
closely with that of the cell 1 ADC input. One useful signal
to provide is a high accuracy voltage reference, such as
3.300V from an LTC6655-3.3. From periodic readings of
this signal, the host software can provide correction of
the LTC6803 readings to improve the accuracy over that
of the internal LTC6803 reference and/or validate ADC
operation. Figure 20 shows a means of selectively pow-
ering an LTC6655-3.3 from the battery stack, under the
control of the GPIO1 output of the LTC6803-1. Since the
operational power of the reference IC would add significant

thermal loading to the LTC6803 if powered from V REG , an
external high voltage NPN pass transistor is used to form
a local 4.4V (V be below V REG ) from the battery stack. The
GPIO1 signal controls a PMOS FET switch to activate the
reference when calibration is to be performed. Since GPIO
signals default to logic high in shutdown, the reference
will automatically turn off during idle periods.
Another useful signal is a measure of the total stack poten-
tial. This provides a redundant operational measurement
of the cells in the event of a malfunction in the normal
acquisition process, or as a faster means of monitoring
the entire stack potential. Figure 21 shows how a resis-
tive divider is used to derive a scaled representation of a
full cell group potential. A MOSFET is used to disconnect
