Product Summary
The LTC6803HG-2#3ZZPBF is a Multicell Battery Stack Monitor. It includes a 12-bit ADC, a precision voltage reference, a high voltage input multiplexer and a serial interface. The LTC6803HG-2#3ZZPBF can measure up to 12 series connected battery cells or supercapacitors. It can be stacked to measure the voltage of each cell in a long battery string. The LTC6803HG-2#3ZZPBF connects the bottom of the stack to V– internally. It is pin compatible with the LTC6802-2, providing a drop-in upgrade. The LTC6803HG-2#3ZZPBF separates the bottom of the stack from V–, improving cell 1 measurement accuracy. The applications of the LTC6803HG-2#3ZZPBF include Electric and Hybrid Electric Vehicles, High Power Portable Equipment, Backup Battery Systems, Electric Bicycles, Motorcycles, Scooters.
