L9963T-TR

L9963T-TR is a general-purpose SPI to isolated SPI transceiver intended to create a communication bridge between devices located in different voltage domains. It is able to transfer communication data incoming from a classical 4-wire-based SPI interface to a 2-wire isolated interface (and vice versa). The transceiver supports both transformer and capacitive isolation since the isolated signal generated according to a proprietary protocol is suitable to be transmitted over both decoupling circuitries. This device can be configured either as a server or as host of the SPI bus and supports any protocol made of SPI frames 8 to 64-bit long. The transceiver manages the transfer of the information without performing any protocol check. It is used in applications such as automotive: 48V and high-voltage systems, backup energy storage systems and UPS, industrial communication networks, portable and semi-portable equipment, and remote sensors.
