Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DDFR against the manufacturer's current orderable addendum to confirm the SOT-23 package variant and tape-and-reel quantity. Ensure the AEC-Q100 Grade 1 qualification aligns with your project's reliability requirements. Cross-reference the datasheet revision history to confirm compatibility with your design specifications before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing nodes requiring robust fault tolerance against load dump events up to 42 V. It is suitable for both commander and responder node architectures due to its integrated pull-up resistor. Consider the thermal resistance characteristics of the SOT-23 package if operating near the maximum junction temperature limit of 150°C.

Drivers, Receivers, Transceivers FAQ

How does the device handle ground disconnection faults?

The TLIN1021A-Q1 provides loss-of-ground fail-safe protection at the system level, preventing back-feed current through the LIN bus to the supply input during ground shifts.

What are the supported wake-up methods?

The device supports local wake-up via the WAKE pin or the EN pin, as well as remote wake-up over the LIN bus while in sleep mode.

Is the RXD output open-drain?

Yes, the RXD pin is an open-drain digital LIN receive data output that requires an external pull-up resistor to the logic supply voltage.
