MLX80004KLW-BAA-001-SP

Drivers, Receivers, Transceivers Overview

The MLX80004KLW-BAA-001-SP is a quad-channel LIN transceiver compliant with LIN 2.x, SAE J2602, and ISO 17987-4 standards. It operates within a battery supply voltage range of 5 V to 27 V and supports an ambient temperature range of -40 °C to +125 °C. The device features selectable baud rates up to 20 kbps in normal mode, 10.4 kbps in low speed mode, and 100 kbps in high speed flash mode. Standby current consumption is typically 100 µA, reducing to approximately 10 µA in sleep mode. It includes integrated master termination, enhanced ESD protection rated at ±10 kV (IEC 61000-4-2), and utilizes a QFN4x4-24 package.

Drivers, Receivers, Transceivers Feature Summary

• Supports dual/quad channel configurations with identical footprints for design flexibility.
• Integrates master termination resistors and decoupling diodes to minimize external components.
• Provides configurable operating modes including High Speed Flash, Low Speed, and Normal speed.
• Features robust fault protection against loss of ground, loss of battery, and short circuits.

Drivers, Receivers, Transceivers Applications

• Automotive Electronic Control Units (ECUs) requiring hard standby current limits.
• LIN bus networks utilizing ISO 9141 systems.
• Applications demanding optimized electromagnetic compatibility (EMC) emissions.
• Master and slave node implementations in single-wire data links.

Drivers, Receivers, Transceivers Procurement Notes

Verify the component status before integration, as it may be marked as Not Recommended for New Designs (NRND). Confirm that the specific ordering suffix matches the required packing form and design revision. Ensure the application environment adheres to the specified thermal and voltage constraints defined in the datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a quad-channel interface is required within a compact QFN4x4 footprint. Consider the MLX80002 variant if only two channels are needed while maintaining the same board layout. Evaluate the need for High Speed Flash mode for rapid data downloads or Low Speed mode for minimized radiated noise in AM bands.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MLX80004 family of enhanced universal LIN transceivers. It serves as a physical layer interface between microcontrollers and the LIN bus. The device is functionally compatible with the previous generation MLX80001 quad master transceiver, allowing for potential backward-compatible upgrades in existing automotive designs.

Drivers, Receivers, Transceivers Replacement Considerations

The MLX80002KLW-BAA-001-SP is a dual-channel version sharing the same package and footprint. Direct substitution requires verifying that the application does not utilize all four available LIN channels. No other direct pin-to-pin replacements are documented in the provided source material.
