Overview

Description

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.

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)
