LIN transceiver offers very low standby current plus strong EMC/ESD behaviour
Based on a 0.35µm HV-CMOS process technology, this transceiver is optimized for very low current operation, so that it draws only 15µA while in standby mode. The integrated standby management function allows it to initiate ‘wake up’ from the LIN bus itself as well as directly from a connected microcontroller or other external source. By generating a reset output signal, the external circuitry necessary for the microcontroller can be reduced.
The MLX80030 delivers the electro-magnetic compatibility required for single wire bus systems. For self-protection, the IC is equipped with an integrated load current limitation and over temperature shutdown, as well as 40V load dump protection. Its electrostatic discharge characteristics allow it to deal with direct discharges of >20kV and indirect discharges of >15KV (in accordance with IEC61000-4-2).
“The EMC behaviour of LIN bus ICs is critical in automotive applications. The MLX80030 displays remarkable resilience when subjected to high frequency disturbances,” says Michael Bender, LIN product line manager for Melexis. “It also achieves excellent ESD robustness to further simplify the design challenges of networked communication in hostile automotive environments.
The MLX80030 is AECQ100 qualified and RoHS compliant. Samples are available on request.
