The LTC6813-1 is a multicell battery stack monitor that measures up to 18 series connected battery cells with a total measurement error of less than 2.2mV. The cell measurement range of 0V to 5V makes the LTC6813-1 suitable for most battery chemistries. All 18 cells can be measured in 290µs, and lower data acquisition rates can be selected for high noise reduction.

Multiple LTC6813-1 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each LTC6813-1 has an isoSPI interface for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection for all devices. This daisy chain can be operated bidirectionally, ensuring communication integrity, even in the event of a fault along the communication path.

The LTC6813-1 can be powered directly from the battery stack or from an isolated supply. The LTC6813-1 includes passive balancing for each cell, with individual PWM duty cycle control for each cell. Other features include an onboard 5V regulator, nine general purpose I/O lines and a sleep mode, where current consumption is reduced to 6µA.

LTC6813-1 Demo Board | 18-Channel Battery-Stack Monitor with Daisy-Chain Interface

LTC6813-1 Demo Board | 18-Channel Battery-Stack Monitor with Daisy-Chain Interface

Product Detail

Demonstration circuit 2350B features the LTC6813-1, 18-channel battery-stack monitor. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI) to monitor a long series of cells in a stack. The DC2350B demo board also features reversible isoSPI enabling a redundant communication path. The PCB, components, and DuraClik connectors are optimized for low EMI susceptibility and emissions.

The DC2350B can communicate to a PC by connecting a DC2792B dual master isoSPI together with DC2026C Linduino® One. The DC2026 must be loaded with the appropriate program (called a sketch) to control the battery-stack monitor IC and receive data through a USB serial port. The DC2026 provides a standard SPI interface which can be translated to isoSPI and then connected to a DC2350B isoSPI port (J4 or J5 connector). The DC2792B companion board provides two SPI-isoSPI channels for reversible operation.

LTC6820 Demo Board | Dual Master isoSPI Adapter

Product Detail

The demonstration circuit DC2792B is an SPI serial to dual-port isoSPI adapter that uses a pair of multiplexed LTC6820 isoSPI transceivers and miniaturized isoSPI connectors (2 contact DuraClik). The board can functionally replace a DC1941 in cases where isoSPI battery-management (BMS) devices are being evaluated, but provides a second isoSPI master to exercise the reversible isoSPI feature where available. The SPI interface can be provided via the legacy 14-contact ribbon cable from either a DC590 or DC2026 USB adapter, or directly installed on the DC2026 as a Linduino shield. The two isoSPI ports are MAIN and AUXiliary, with activity of each indicated by blue LEDs. For use in place of DC1941 or non-reversible isoSPI networks, the MAIN port must be used. Power for the DC2792B comes indirectly from the USB port of the host computer, via the USB to serial adapter being used.
