ADILTC6804IG-1#PBF

Overview

The LTC6804IG-1#PBF is a third-generation multicell battery stack monitor capable of measuring up to 12 series-connected battery cells. It features a sub-1.2mV total measurement error and a proprietary isoSPI interface for high-speed, RF-immune local area networking between multiple devices in a high-voltage stack.

Why Choose This Part

The device offers exceptional measurement precision and features a built-in isoSPI interface which allows for long-distance communication over a simple twisted pair, significantly reducing wiring complexity and cost in high-voltage environments. It supports multiple battery chemistries and includes integrated passive balancing control for each cell.

Applications

Getting Started

Engineers should evaluate this IC using the DC2100A or DC1894B evaluation boards from Analog Devices. The -1 variant uses a daisy-chain interface, so ensure your microcontroller is interfaced via an LTC6820 isoSPI transceiver if galvanic isolation is required for the SPI bus.
