Jul 1, 2019 · SPI is a synchronous serial data bus that facilitates data exchange between the devices and the central control unit over long distances. The communication takes place according to the master-slave principle and is full duplex. The SPI interface is made up of three lines: SDI, SDO, and SCK.

Apr 1, 2014 · The isoSPI ™ feature built into the LTC6804 battery stack monitor, when combined with an LTC6820 isoSPI communications interface, enables safe and robust information transfer across a high voltage barrier. isoSPI is particularly useful in energy storage systems that produce hundreds of volts via series-connected cells, which require full dielectric isolation to minimize …

The serial peripheral interface (SPI) bus is an unbalanced or single-ended serial interface designed for short-distance communication between integrated circuits.

Jan 11, 2017 · The LTC6820 provides a method of interconnecting standard serial peripheral interface (SPI) devices using a single twisted pair connection. This proprietary 2-wire interface is called isoSPI.

The WE-BMS series supports serial Daisy Chain, isoSPI, SPI and other signal isolations. Single and dual transformer for one or two channels are available.

The LTC®6820 provides bidirectional SPI communications between two isolated devices through a single twisted-pair connection. Each LTC6820 encodes logic states into signals that are transmitted across an isolation barrier to another LTC6820.

Nov 11, 2019 · Analog Devices Inc. LTC6820 isoSPI Transceiver provides bidirectional Serial Peripheral Interface (SPI) communications between two isolated devices through a single twisted-pair connection.

Allows signal and power transfer between controller devices and peripheral ICs Protects low voltage parts in a system from high voltage circuits Diminishes the effect of ground potential difference [FAQ] How to connect SPI MCU to multiple isolated SPI nodes? [FAQ] How to calculate the maximum SPI speed supported by a digital isolator?

The selection of the appropriate isolation depends on the interface (SPI or I2C) used. Discrete or integrated isolated power supplies can be selected depending on the trade-offs of emissions, board space and design simplicity.

The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usu-ally. It is based on Linear's LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and …
