MLX81150LLW-DAA-000-SP

Overview

The MLX81150LLW-DAA-000-SP is a LIN slave controller designed for relay and DC motor control applications. It integrates an MLX16x8 16-bit RISC CPU with a co-processor, 32 kB Flash with ECC, 2 kB RAM, and 380 B EEPROM. The device features an integrated LIN transceiver supporting LIN 2.x and SAE J2602, four 16-bit PWM modules, two relay drivers, and an internal voltage regulator operating between 5.5V and 18V. It includes diagnostic features such as over-current detection, shunt current sensing, and a temperature sensor. The component is housed in a QFN32 5x5 package and supports an ambient temperature range of -40°C to 150°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and delivery form. Confirm that the required temperature range and firmware version align with project specifications. Check for any recent updates to the datasheet regarding assembly information or environmental compliance declarations before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a single-chip solution for high-current DC motor or relay control via LIN bus. Ensure external circuitry supports the 5.5V to 18V operating voltage range and provides necessary reverse polarity protection. Consider the need for external Hall sensors for position sensing and verify that the QFN32 package thermal characteristics meet the system's heat dissipation requirements.
