Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific suffix KDC-AAA-014-SP matches the required temperature grade and packaging configuration for your design. Confirm compliance with GMW3089 V2.3 requirements before finalizing the bill of materials. Ensure software implementations account for the 100µs debounce period following local wake-up events as detailed in application notes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring strict adherence to GMW3089 V2.3 standards for single-wire communication. Consider the 5V to 27V operating range and the 30 µA standby current for power-sensitive automotive environments. Evaluate the need for high-speed modes up to 100 kbps if assembly line data transfer capabilities are necessary for the target application.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Melexis TH8056 family of single-wire CAN transceivers. The family is engineered specifically for automotive B-class networks where cost-effective physical media and lower data rates are prioritized over high-speed performance. These devices support various CSMA/CR protocols and provide essential electrical protections for harsh automotive environments.

Verify compatibility with existing system designs by cross-referencing pinouts and electrical characteristics with alternative single-wire CAN transceivers from other manufacturers if sourcing constraints arise.

Drivers, Receivers, Transceivers FAQ

How should the MCU handle the RxD line during local wake-up?

The MCU must debounce the RxD line via software for 100µs after local wake-up to prevent unintended pulses caused by regulator startup and RS flip-flop switching.

What causes the brief RxD pulse observed after local wake-up?

The pulse is caused by the internal 5V regulator start-up sequence and the preferred switching behavior of the internal RS flip-flop, which can generate a brief pulse approximately 10µs to 43µs after the transition.

Is the RxD interrupt used during active bus wake-up?

No, during active bus wake-up the RXD line remains at a low level, so no pulse is observed. This active low level can be used as an interrupt if the INH pin is not utilized for regulator control.
