The MAX17841B ASCI combines an SPI port with a universal asynchronous receiver transmitter (UART) specially designed to interface with Maxim battery management devices. The UART can be configured to automatically perform Manchester encoding/decoding, message framing, parity, wake-up, and keep-alive signaling as required for Maxim’s battery management UART protocol. The UART has programmable baud rates of 0.5Mbps, 1Mbps, or 2Mbps and supports either single-ended or differential signaling. For host efficiency, the UART contains a 28-byte transmit buffer and a 62-byte receive buffer with host-configurable interrupt events. Applications * Battery Management Systems (BMS) * Electric and Hybrid Vehicles (EV/HEV) * Energy Storage Systems (ESS) * Supports Maxim’s Battery Management UART Protocol * SPI Interface Up to 4MHz * UART Baud Rate Programmable Up to 2Mbps * 3.3V or 5V Operation * Ultra-Low Quiescent Current * Transmit and Receive Buffers with Programmable Interrupts Allow for Queuing of UART Messages * Manchester Encoder and Decoder Reduces Host Controller Burden * Operating Temperature Range from -40°C to +105°C (AEC-Q100 Type 2) * Supports ASIL Requirements https://elecena.pl/product/22319433/automotive-spi-communication-interface-asci 2022-12-27 https://elecena.pl/product/22319433/automotive-spi-communication-interface-asci 2024-11-04 https://elecena.pl/product/22319433/automotive-spi-communication-interface-asci 2024-11-09 https://elecena.pl/product/22319433/automotive-spi-communication-interface-asci 2025-01-19
