NXP MC33665ATS4AE Communication Gateway Battery Management -40 °C to 125 LQFP-48 New

MC33665A is a general-purpose battery management communication gateway and transport protocol link (TPL) transceiver. The device forwards messages upcoming from different TPL (isolated daisy chain protocol of NXP) ports through a standard communication protocol. It is designed as a gateway for serial peripheral interface (SPI), CAN (FD) or universal asynchronous receiver transmitter (UART) to TPL. In the SPI or UART variant, the device communicates directly to the MCU by using SPI or UART. This transfers messages between MCU and battery management system (BMS) devices connected to integrated TPL ports. It provides four TPL ports to communicate with other isolated BMS devices in the daisy chain.

• MCU host interface supporting SPI, CAN (FD) or UART, full duplex operation
• Selectable IO voltage of 5V or 3.3V, message buffering, configurable response and request buffers
• Status/handshake signals for data flow control, communication management unit
• Multi-port TPL interface, four independent TPL daisy chain ports
• Automatic message routing based on address of TPL message, SPI gateway with four TPL ports
• 2Mbit/s data rate, two-wire daisy chain supporting capacitive or inductive isolation
• Message synchronization, enables synchronization of messages across all TPL daisy chain ports
• Transmission of messages triggered by external event (SYNC)
• TPL daisy chain, MCU communication, wake-up input, sleep mode (25µA typical)
• AEC-Q100 grade 1 qualified, -40°C to +125°C ambient temperature range
