Product details
Overview
MLX81150LPF-DAA-000-TR from Melexis is a LIN slave IC for automotive relay and DC motor control, integrating a 16-bit RISC CPU, dual integrated relay drivers (Ron < 7 Ω @150°C), 4-channel 16-bit PWM, 10-bit ADC with DMA, and LIN 2.x/SAE J2602 transceiver - deployed in window lifters, sun roofs, and fuel pumps.
For engineers reviewing the MLX81150LPF-DAA-000-TR datasheet, pinout, applications, or equivalent options, key selection criteria include its QFN32 5×5 mm package, -40°C to 150°C ambient operation, 5.5–18 V supply range, integrated voltage regulator, and LIN-based system-level motor coordination without external transceiver.
Technical Context
The MLX81150LPF-DAA-000-TR implements a monolithic LIN slave architecture with on-chip LIN protocol stack certified per LIN 2.x and SAE J2602, enabling direct bus communication without host MCU intervention. Its MLX16x8 RISC core includes co-processor acceleration for multiplication/division and supports in-circuit debug via TI1/TI2/TO pins.
It integrates dual low-side relay drivers with freewheeling diodes, two shunt current sense inputs (SENSE1/SENSE2), four independent 16-bit PWM modules, and a 25 MHz ±5% RC oscillator with optional crystal support - all operating under a single 12 V battery supply with internal 3.3 V and 1.8 V regulators.
Key Specifications

|---|---|
| Supply Voltage Range | 5.5 V to 18 V (operates down to 3.9 V with digital-only functionality; enables direct 12 V battery connection) |
| Operating Temperature | -40°C to 150°C ambient (AEC-Q100 qualified; extended range requires external bypass transistor) |
| LIN Compliance | LIN 2.x and SAE J2602 certified; integrated physical layer and protocol stack - eliminates need for external LIN transceiver |
| Relay Drivers | 2 integrated low-side switches (REL1/REL2), Ron < 7 Ω @150°C with freewheel function - drives 150 mA loads directly |
| PWM Outputs | 4 × 16-bit PWM channels (PWM1–PWM4), push-pull, Ron < 50 Ω @20 mA - suitable for FET gate driving in full-bridge motor control |
| ADC | 10-bit SAR ADC, < 6 µs conversion time, multiple channels, selectable references, DMA access to RAM - supports real-time motor current and VBAT monitoring |
| Memory | 32 kB Flash (with ECC), 2 kB RAM, 380 B EEPROM/NVRAM (with ECC) - sufficient for LIN firmware, motor control algorithms, and calibration data storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN slave motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon TLE9183QX | 3-channel high-side driver; no integrated LIN transceiver; requires external LIN PHY; 40 V max VS | Targeted at high-side switched loads (e.g., solenoids); lacks integrated relay drivers and shunt sense inputs | Choose when high-side switching and higher voltage tolerance are required, but expect added BOM and layout complexity |
| NXP MC33816 | Standalone LIN transceiver + separate 3-channel high-side driver; no MCU core or PWM peripherals | Requires external microcontroller for logic and timing; suited for distributed architectures where LIN and power stages are decoupled | Prefer when system partitioning is mandatory or when legacy MCU firmware must be reused across platforms |
Compared with TLE9183QX and MC33816, the MLX81150LPF-DAA-000-TR delivers higher integration by combining LIN protocol handling, MCU execution, relay driving, and analog sensing in one QFN32 package - reducing total solution size, component count, and software development effort for single-motor LIN nodes.

FAQ
What is the maximum ambient temperature rating for MLX81150LPF-DAA-000-TR?
The MLX81150LPF-DAA-000-TR is rated for -40°C to 150°C ambient operation per AEC-Q100 Grade 0. At temperatures above 105°C, use of an external bypass transistor (connected to RTG) is mandatory to limit junction temperature, and extended high-temp usage requires customer mission profile agreement with Melexis.
Does MLX81150LPF-DAA-000-TR require an external LIN transceiver?
No, MLX81150LPF-DAA-000-TR includes a fully integrated LIN transceiver compliant with LIN 2.x and SAE J2602 standards. The LIN pin connects directly to the bus line with only passive filtering components required - eliminating the need for external transceivers like TJA1020 or UJA1075.
Can MLX81150LPF-DAA-000-TR drive BLDC motors?
Yes, MLX81150LPF-DAA-000-TR supports 1- and 2-phase BLDC motor control using Hall sensor inputs (TC1/TC2) for commutation timing and its four 16-bit PWM channels for phase drive. Application Note section 4.5 confirms implementation in auxiliary pumps and blowers with LIN interface.
What is the purpose of the PS pin on MLX81150LPF-DAA-000-TR?
The PS pin is a switchable high-side supply output (<15 V, Ron < 40 Ω at 20 mA) used to power external Hall sensors or other peripherals. It can be enabled/disabled via firmware to reduce standby current - critical for battery-powered modules like sun roof controllers.
How does MLX81150LPF-DAA-000-TR handle overcurrent protection?
MLX81150LPF-DAA-000-TR provides overcurrent detection through dedicated SENSE1 and SENSE2 inputs that monitor relay contact voltage drop or external shunt resistor voltage. Combined with its 10-bit ADC and programmable thresholds, it enables fast shutdown and fault reporting over LIN without external comparators.
