Overview
LTC6803-1/LTC6803-3 Multicell Battery Stack Monitor FEATURES n n n n n n n n n n n n n n n n n DESCRIPTION The LTC®6803 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.
Using a unique level shifting serial interface, multiple LTC6803-1/ LTC6803-3 devices can be connected in series, without opto-couplers or isolators, allowing for monitoring of every cell in a long string of series-connected batteries.
Each cell input has an associated MOSFET switch for discharging overcharged cells.
The LTC6803-1 connects the bottom of the stack to V– internally.
It is pin compatible with the LTC6802‑1, providing a drop-in upgrade.
The LTC6803-3 separates the bottom of the stack from V–, improving cell 1 measurement accuracy.
The LTC6803 provides a standby mode to reduce suppl...
