Linear Technology LTC6803-1/LTC6803-3 Datasheet
The LTC6803‑1 and LTC6803‑3 are high‑precision 12‑channel battery‑monitoring ICs that integrate a 12‑bit ADC, voltage reference, and multiplexed high‑voltage inputs. They support serial daisy‑chain communication without opto‑isolators and include integrated MOSFETs for cell balancing and external MOSFET drive.
Typical applications include electric vehicles, hybrid‑electric vehicles, high‑power portable devices, backup battery systems, electric bicycles, and other multi‑cell battery packs. The devices are offered in a 44‑lead plastic SSOP package and feature low standby current and robust EMI immunity.
