Product details
Overview
MLX90316LDC-BCS-000-TU from Melexis is an absolute rotary position sensor IC using Triaxis® Hall technology to measure angular position of an end-of-shaft dipole magnet with 12-bit resolution, ±1° intrinsic linearity error, and operation up to +150°C in SOIC-8 package. It delivers ratiometric analog, PWM, or SPI output and supports programmable transfer characteristics for throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90316LDC-BCS-000-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its -40°C to +150°C operating range, SOIC-8 single-die packaging, 12-bit angular resolution, programmable clamping/linearity, and integrated diagnostics for automotive position feedback systems.
Technical Context
The MLX90316LDC-BCS-000-TU integrates a Triaxis® magnetic front-end with on-chip IMC to sense horizontal flux components, enabling robust angular measurement across mechanical airgap and off-axis tolerances. Its 16-bit RISC DSP performs real-time arctangent computation and digital signal conditioning.
It supports three output modes-ratiometric analog (0–100% VDD), 12-bit PWM (100–1000 Hz), or 14-bit SPI serial-with full end-of-line programmability of offset, gain, clamping, deadzone, and filtering via PTC-04 tool through VDD/VSS/OUT pins only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | -40°C to +150°C - qualified for under-hood automotive applications without derating |
| Angular Resolution | 12-bit (0.0879°/LSB) - enables precise closed-loop motor control and pedal feedback |
| Intrinsic Linearity Error | ±1° at TA = 25°C - base accuracy before multi-point calibration improves system-level linearity |
| Output Options | Ratiometric analog, 12-bit PWM, or 14-bit SPI - selectable per application EMI/noise requirements |
| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V automotive power rails |
| Supply Current | 8.5–16 mA - dual-mode operation (slow/fast) allows trade-off between power and response time |
| Magnetic Range | 20–70 mT - optimized for small NdFeB dipole magnets with minimal size/cost impact |
Pinout & Package
MLX90316LDC-BCS-000-TU uses RoHS-compliant SOIC-8 package with integrated magneto-concentrator (IMC) positioned over die center. Pin 1 is VDD; unused pins (2, 4, 6, 8) must be connected to VSS for EMC compliance per datasheet Section 16.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); powers internal regulator and logic |
| 2 | Test 0 | Factory test pin; must be tied to VSS for production use |
| 3 | Switch OUT | Programmable digital switch output with hysteresis; configurable as diagnostic flag or position threshold |
| 4 | Not Used / OUT2 | No connection in SOIC-8 single-die variant; reserved for dual-die TSSOP-16 |
| 5 | OUT | Primary output: analog voltage, PWM, or SPI data depending on configuration |
| 6 | Test 1 | Factory test pin; must be tied to VSS for production use |
| 7 | VDIG | Digital supply reference for output stage; decoupling required near pin |
| 8 | VSS | Analog/digital ground return; mandatory low-impedance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Sensing Architecture | Measures horizontal magnetic field components (VX/VY) via on-die IMC, eliminating need for external flux concentrators or complex magnet alignment |
| End-of-Line Programmability | Full transfer function tuning (offset, gain, clamping, linearity, filtering) via PTC-04 using only VDD/VSS/OUT pins - no dedicated programming interface required |
| Integrated Diagnostics | Real-time broken-track detection (VDD/VSS loss), thermal drift compensation, and watchdog timeout - reduces need for external safety monitoring circuits |
| Multi-Mode Output Flexibility | Single hardware design supports analog (ratiometric), PWM (100–1000 Hz), or SPI (14-bit angle + status) outputs - simplifies platform reuse across vehicle ECUs |
| High-Temperature Operation | Validated performance up to +150°C ambient - suitable for direct mounting on transmission housings, brake calipers, or engine throttle bodies |

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 |
|---|---|---|---|
| MLX90363KGO-ABD-000-SP | TSSOP-16 dual-die package with full redundancy; 14-bit SPI-only output; -40°C to +125°C rating | Targeted at ASIL-D systems requiring hardware redundancy; lacks analog/PWM outputs | Select when functional safety certification (ISO 26262) mandates dual-channel fault detection and isolation |
| AMS AS5055A-BQFT | 14-bit contactless angle sensor; SPI/I²C interface only; no analog/PWM; -40°C to +125°C; QFN-16 package | Optimized for space-constrained PCBs; requires external ADC for analog interface | Select when board area is critical and serial interface suffices; verify magnetic field sensitivity (±60 mT) matches magnet geometry |
Compared with MLX90316LDC-BCS-000-TU, the MLX90363 offers hardware redundancy but sacrifices output flexibility and high-temp capability, while the AS5055A provides higher resolution and smaller footprint but lacks analog/PWM and extended temperature support.

FAQ
What output modes does the MLX90316LDC-BCS-000-TU support?
The MLX90316LDC-BCS-000-TU supports three configurable output modes: ratiometric analog voltage (0–100% VDD), 12-bit PWM (100–1000 Hz), and 14-bit SPI serial protocol. Mode selection is programmed via the PTC-04 tool during end-of-line calibration using only VDD, VSS, and OUT pins - no dedicated programming interface is required. The MLX90316LDC-BCS-000-TU does not support I²C or UART interfaces.
Does the MLX90316LDC-BCS-000-TU require external magnetics or flux concentrators?
No, the MLX90316LDC-BCS-000-TU integrates an on-die Integrated Magneto-Concentrator (IMC) that focuses magnetic flux onto the Triaxis® Hall sensing elements. This eliminates the need for external flux concentrators or complex magnet positioning, enabling robust operation with simple end-of-shaft dipole magnets. The MLX90316LDC-BCS-000-TU is specified for 20–70 mT magnetic fields and maintains ±1° linearity within this range.
What is the maximum operating temperature for the MLX90316LDC-BCS-000-TU?
The MLX90316LDC-BCS-000-TU is rated for continuous operation from -40°C to +150°C ambient temperature, validated per its 'L' temperature suffix. This makes it suitable for under-hood automotive applications such as throttle bodies, transmission shifters, and brake pedal assemblies where sustained high-temperature exposure occurs. The MLX90316LDC-BCS-000-TU maintains full electrical specifications across this range without derating.
Can the MLX90316LDC-BCS-000-TU be calibrated for custom angular ranges?
Yes, the MLX90316LDC-BCS-000-TU supports full end-of-line programmability of its angular transfer characteristic, including programmable start/end points (0–360°), linearization coefficients, clamping thresholds, deadzone, and filtering parameters. Calibration is performed using the Melexis PTC-04 programming unit via the standard VDD-VSS-OUT pins - no additional hardware interface is needed. The MLX90316LDC-BCS-000-TU stores all calibration data in on-chip EEPROM.
Is the MLX90316LDC-BCS-000-TU pin-compatible with other MLX90316 variants?
The MLX90316LDC-BCS-000-TU uses the SOIC-8 package and shares identical pinout with all other 'DC' (SOIC-8) variants, including MLX90316EDC-BCS-000-TU and MLX90316KDC-BCS-000-TU. However, it is not pin-compatible with 'GO' (TSSOP-16) dual-die variants due to different pin count, layout, and internal redundancy architecture. The MLX90316LDC-BCS-000-TU pinout is defined in datasheet Section 4 and Figure 19.2.
