Product Details
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.
Key Features
- 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
Applications/Uses
- Battery Management Systems (BMS)
- Electric and Hybrid Vehicles (EV/HEV)
- Energy Storage Systems (ESS)
