MC33665ATF4AER2

MC33665ATF4AER2 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. The standard communication protocol ensures compatibility with microcontrollers available in the market. 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. It transfers messages between MCU and battery management system (BMS) devices connected to integrated TPL ports. In the CAN FD variant, it can be communicated with the controller area network (CAN) and CAN FD to send and receive messages to BMS devices connected on TPL ports. The device powers an external CAN transceiver to be a part of a CAN bus.
