LTC6803HG-4
PDF Specification
The LTC6803 is a 2nd generation, complete battery monitoring
IC that includes a 12-bit ADC,a precision voltage
reference, a high voltage input multiplexer and a serial
interface. Each LTC6803 can measure up to 12 series
connected battery cells or supercapacitors. Many LTC6803
devices can be stacked to measure the voltage of each cell
in a long battery string. Each LTC6803-2/LTC6803-4 has
an individually addressable serial interface, allowing up
to 16 LTC6803-2/LTC6803-4 devices to interface to one
control processor and operate simultaneously. Each cell
input has an associated MOSFET switch for discharging
overcharged cells. The LTC6803-2 connects the bottom
of the stack to V– internally. It is pin compatible with the
LTC6802-2, providing a drop-in upgrade. The LTC6803-4
separates the bottom of the stack from V–, improving
cell 1 measurement accuracy.
The LTC6803 provides a standby mode to reduce supply
current to 12µA. Furthermore, the LTC6803 can be powered
from an isolated supply, providing a technique to reduce
battery stack current draw to zero.
The related LTC6803-3 offer a serial in-terface that allowsthe serial ports of multiple LTC6803-1 or LTC6803-3 devices to be daisy chained without opto-couplers or isolators.
