Product details
Overview
MLX90324LDC-DBO-100-SP from Melexis is an absolute rotary position sensor IC based on Triaxis® Hall technology, delivering 12-bit angular resolution and ±10-bit thermal accuracy over −40°C to +150°C. It supports SENT (SAE-J2716), ratiometric analog, and PWM outputs, and features programmable 360° angular range and 16-point linear transfer characteristic for throttle, EGR, and manifold actuator applications.
For engineers reviewing the MLX90324LDC-DBO-100-SP datasheet, pinout, applications, or equivalent options, key selection criteria include high-temperature operation up to 150°C, SENT protocol compliance, SOIC-8 package compatibility, and end-user programmability of clamping, deadzone, and switch-out behavior.
Technical Context
The MLX90324LDC-DBO-100-SP integrates a dual-Hall front-end with Integrated Magneto-Concentrator (IMC™) to sense in-plane magnetic flux (BX, BY) from a diametrically magnetized rotating magnet. Its DSP computes angle via arctangent lookup table (not CORDIC), enabling intrinsic self-compensation against airgap and thermal drift.
It implements a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), with 10 kB ROM, 256 B RAM, and 128 B EEPROM featuring Hamming ECC. Output modes are selected via firmware-configurable registers, and diagnostics include broken-track detection, watchdog timeout, and resonant fault monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90316LDC-AAA-000-RE | Lacks SENT protocol; only supports analog and PWM; lower max operating temperature (+125°C) | Suitable for less demanding under-hood locations (e.g., HVAC actuators) but not EGR or turbo proximity | Select when SENT is unnecessary and cost optimization is prioritized over extreme temperature capability |
| AMS AS5055A-BQFT | Uses SPI interface instead of SENT; no integrated switch-out; 14-bit resolution but only rated to +125°C | Requires external MCU for protocol translation; lacks built-in diagnostics like broken-track detection | Choose for SPI-based embedded systems needing higher raw resolution, but accept added software overhead and reduced functional safety coverage |
Compared with MLX90316LDC-AAA-000-RE and AMS AS5055A-BQFT, the MLX90324LDC-DBO-100-SP uniquely combines SENT compliance, +150°C operation, and integrated switch-out - making it the only option qualified for direct replacement in ASIL-B throttle and EGR subsystems without redesign.

FAQ
What output protocols does the MLX90324LDC-DBO-100-SP support?
The MLX90324LDC-DBO-100-SP supports three user-selectable output protocols: SENT (SAE-J2716 Rev 2010), ratiometric analog (0–100% VDD), and PWM (100–1000 Hz). Configuration is performed via internal EEPROM programming using the Melexis PTC-04 tool and MLX90316/90324 daughterboard - no external pins are required for mode selection. The SENT implementation includes CRC, status nibbles, and diagnostic reporting per standard requirements.
Does the MLX90324LDC-DBO-100-SP require an external magnet, and what type is recommended?
Yes, the MLX90324LDC-DBO-100-SP requires an external diametrically magnetized magnet positioned above the IC surface. Melexis recommends neodymium magnets with Br ≥ 1.2 T and dimensions ~5 mm diameter × 2 mm thickness, placed within 1–3 mm airgap. Magnetic field strength must stay within 20–70 mT at the sensor die; exceeding 70 mT causes IMC saturation and linearity degradation. Magnet temperature coefficient (−2400 ppm/°C) must be considered for high-temp applications.
How is the MLX90324LDC-DBO-100-SP calibrated for angular linearity?
The MLX90324LDC-DBO-100-SP supports two calibration methods: 3-point linearization (for basic offset/gain/clamp adjustment) and 16-point LUT-based correction. Calibration parameters - including LNR_A_X/Y/S through LNR_C_X/Y/S and all 17 Y-coordinates for 16-point mode - are programmed into EEPROM using the PTC-04 tool. The DSP applies these corrections post-ATAN computation, enabling compensation for mechanical misalignment, magnet non-uniformity, and housing-induced field distortion without hardware changes.
What diagnostic functions are built into the MLX90324LDC-DBO-100-SP?
The MLX90324LDC-DBO-100-SP integrates multiple hardware-level diagnostics: broken VDD/VSS detection (via BVDDPD/BVSSPD thresholds), resonant fault monitoring (RESONFAULT), watchdog timeout (5 ms), EEPROM Hamming ECC error flagging, and active diagnostic output signaling. These features operate autonomously without MCU intervention and meet ASIL-B readiness per ISO 26262. Diagnostic status is reported via dedicated SENT nibbles or analog voltage bands (e.g., 4–12% VDD for low-band faults).
Can the MLX90324LDC-DBO-100-SP operate in redundant configurations?
No - the MLX90324LDC-DBO-100-SP uses a single-die SOIC-8 configuration (Package Code DC). Redundancy is only available in the dual-die TSSOP-16 variant (e.g., MLX90324LGO-DBO-000-RE), which provides isolated signal paths and 4 MΩ inter-die isolation resistance. For MLX90324LDC-DBO-100-SP, functional safety must be achieved via system-level redundancy (e.g., dual sensors with cross-checking) rather than monolithic hardware redundancy.
