Working Principles

L9613B operates based on the Controller Area Network (CAN) protocol. It receives data from a microcontroller through the TXD pin and transmits it over the CAN bus using differential signals on the CANH and CANL pins. The transceiver also receives data from the bus and sends it to the microcontroller through the RXD pin. This bidirectional communication enables seamless data exchange between different nodes on the CAN network.

Detailed Application Field Plans

L9613B is widely used in various automotive applications, including: - Engine control units (ECUs) - Transmission control units (TCUs) - Body control modules (BCMs) - Anti-lock braking systems (ABS) - Airbag control units (ACUs) - Instrument clusters - Electric power steering systems - HVAC (Heating, Ventilation, and Air Conditioning) systems
