MAX17841BGUE/V+

MAX17841BGUE/V+ is an automotive SPI communication interface. It combines an SPI port with a universal asynchronous receiver transmitter (UART) designed to interface with Analog Device's battery management devices. The UART can be configured to automatically perform manchester encoding/decoding, message framing, parity, wake-up, and keep-alive signalling as required for Analog Device's battery management UART protocol. For host efficiency, the UART contains a 28-byte transmit buffer and a 62-byte receive buffer with host-configurable interrupt events. It is used in applications such as battery management systems, electric and hybrid vehicles (EV/HEV), energy storage systems (ESS).

• Supports Analog Device's battery management UART protocol, SPI interface up to 4MHz
• 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
• Supply voltage is 3.3V typical at (VDCIN = VAA = VDDL = 3.3V nominal)
• Supply current is 4mA typical at (VDCIN = 5V, VAA = VDDL = 3.3V)
• SCLK frequency is 4MHz maximum at (VDCIN = 5V, VAA = VDDL = 3.3V)
• Oscillator frequency is 16MHz typical at (VDCIN = 5V, VAA = VDDL = 3.3V)
• Operating temperature range from -40°C to +105°C
• 16-pin TSSOP package
