MAX17851 SPI to UART Safety Monitoring Bridge

Analog Devices MAX17851 SPI to UART Safety Monitoring Bridge allows a host controller with a standard SPI port to reliably communicate with one or more battery management monitors that use the battery management UART protocol. The safety monitoring bridge enables robust communication with baud rates extending up to 4Mbps in single and dual daisy-chain system architectures. The UART is ISO26262 compliant for Automotive Safety Integrity Level (ASIL) D systems to detect message corruption, delay, loss, and insertion through the embedded UART communication Lockstep Safety-Measure State Machine (LSSM). The MAX17851 self-verifies all communication within the message payload to simplify the software development on the host microcontroller.
