Key Features
- Fault-Tolerant Design: The device can switch to single-wire transmitter and/or receiver in error conditions, ensuring continuous communication even in faulty states.
- Low Electromagnetic Emission (EME): Very good matching of the CANL and CANH output signals reduces EME, especially in low power modes.
- Good Electromagnetic Immunity (EMI): The device offers good EMI in both normal operating mode and low power modes.
- Full Wake-Up Capability: The device supports wake-up during bus failures and has a two-edge sensitive wake-up input signal via the WAKE pin.
- Bus Failure Management: Extended bus failure management includes short-circuit of the CANH bus line to VCC and support for single-wire transmission modes with ground offset voltages up to 1.5 V).
- Integrated Receiver Filters: Fully integrated receiver filters enhance signal quality and noise immunity).
- Transmit Data (TxD) Dominant Time-Out Function: Ensures proper signal transmission and prevents data corruption).
