Product details

Overview

MLX90316KGO-BCG-300-TU from Melexis is a Triaxis® absolute rotary position sensor IC for end-of-shaft dipole magnet sensing, delivering 14-bit serial (SPI), 12-bit analog ratiometric, or 12-bit PWM angular output with ±0.3° thermal accuracy over –40°C to +125°C and programmable 0–360° range. It integrates IMC-based magnetic front-end, on-chip DSP, EEPROM, and diagnostics for automotive throttle, pedal, and steering wheel position sensing.

For engineers reviewing the MLX90316KGO-BCG-300-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16 dual-die), confirmed SPI/Analog/PWM output modes, calibrated transfer function parameters, diagnostic capabilities including broken-track detection, and real-world use cases in safety-critical vehicle subsystems.

Technical Context

The MLX90316KGO-BCG-300-TU implements Triaxis® sensing using an integrated magneto-concentrator (IMC) to detect horizontal magnetic field components from an end-of-shaft dipole magnet, enabling robust angular measurement across mechanical airgap and off-axis tolerances. Its dual-die TSSOP-16 architecture provides full redundancy with isolated VDD1/VSS1 and VDD2/VSS2 domains.

On-chip 16-bit RISC DSP processes raw sine/cosine ADC data (14-bit fast mode, 15-bit slow mode) into absolute angle, supports end-of-line calibration of offset, gain, clamping, linearity, and filtering via PTC-04 programmer, and delivers output via three selectable protocols: ratiometric analog (VOUT), PWM (FPWM = 100–1000 Hz), or 14-bit SPI (MOSI/MISO/SCLK/SS).

Key Specifications

Pinout & Package

TSSOP-16 dual-die package with fully redundant signal paths, RoHS-compliant, 4.4 mm × 5.0 mm footprint, 1.2 mm height, and exposed thermal pad (not electrically connected). Pin 1 marked by dot; pins 4, 6, 8, 12, 14 are test points; unused pins must be grounded for EMC compliance.

Pin/Terminal	Circuit Role	Design Meaning
1, 11	VDD1 / VDD2	Independent power supply inputs for die 1 and die 2; each requires local 100 nF decoupling
2, 10	VSS1 / VSS2	Independent ground returns for die 1 and die 2; must be connected to system ground at single point
3, 13	/SS1 / /SS2	Active-low slave select for SPI interface per die; enables independent communication or synchronized readout
4, 12	Test 01 / Test 11	Factory test access; not user-configurable; recommended tied to VSS for EMC
5, 15	OUT1 / OUT2	Dual independent outputs: OUT1 = primary analog/PWM; OUT2 = secondary analog/PWM (PPD pre-programmed digital mode)
6, 14	SCLK1 / SCLK2	Serial clock inputs for SPI per die; supports daisy-chain or parallel timing control
7, 16	MOSI1/MISO1 / MOSI2/MISO2	Shared bidirectional data line per die; supports full-duplex SPI reads/writes with status feedback
9	VDIG2	Digital supply for die 2's logic and SPI interface; separate from analog VDD2

Key Features

Feature	Design Value
Triaxis® IMC Sensing	Enables contactless, high-tolerance angular measurement using only a small dipole magnet mounted end-of-shaft
Full Dual-Die Redundancy	TSSOP-16 layout isolates power, ground, and signal paths between two independent sensor dies for ASIL-B/C compliance
End-of-Line Programmability	40-bit ID + 128 B EEPROM allows field calibration of transfer function, clamping, deadzone, and filter coefficients via PTC-04
Multi-Protocol Output	Single device supports analog ratiometric, PWM, and SPI - eliminates need for external signal conditioning or protocol translation
Integrated Diagnostics	Real-time broken-track (VDD/VSS), watchdog timeout, and configurable output clamping ensure functional safety monitoring without external circuitry

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-ABG-300-TU	Higher 16-bit SPI resolution (0.0055°/LSB), integrated temperature sensor, same TSSOP-16 dual-die package	Required for applications needing <±0.1° total angular error or closed-loop thermal compensation	Choose when higher resolution and on-chip temperature data justify cost premium over MLX90316KGO-BCG-300-TU

FAQ

What output protocols does the MLX90316KGO-BCG-300-TU support?

The MLX90316KGO-BCG-300-TU supports three user-selectable output protocols: ratiometric analog voltage (0.1–4.9 V), PWM (100–1000 Hz, 12-bit resolution), and 3-wire SPI (14-bit angle + status flags). All modes are configured via EEPROM programming using the PTC-04 tool; the MLX90316KGO-BCG-300-TU ships pre-programmed for digital (PPD) mode with SPI enabled by default.

Does the MLX90316KGO-BCG-300-TU include built-in diagnostics?

Yes, the MLX90316KGO-BCG-300-TU integrates multiple hardware-level diagnostics: broken-VDD and broken-VSS detection, watchdog timer (5 ms timeout), configurable clamping/hysteresis, and SPI status flags for communication errors. These features are active in all output modes and require no external components, supporting ISO 26262 functional safety requirements up to ASIL-B.

What is the angular accuracy specification of the MLX90316KGO-BCG-300-TU over temperature?

The MLX90316KGO-BCG-300-TU achieves ±0.3° total angular error over –40°C to +125°C, combining thermal offset drift (<±60 LSB15 at DSP input), DAC/output stage drift (<±0.3%VDD), and sensitivity mismatch drift (<±0.3%). This value reflects worst-case deviation after factory calibration and applies to both analog and SPI outputs under specified magnetic conditions (20–70 mT).

How is redundancy implemented in the MLX90316KGO-BCG-300-TU?

The MLX90316KGO-BCG-300-TU uses a true dual-die architecture in TSSOP-16: two physically separate silicon dies share one package but have independent VDD1/VSS1 and VDD2/VSS2 power domains, isolated signal paths (OUT1/OUT2, SCLK1/SCLK2, MOSI1/MISO1 etc.), and separate EEPROM memory. This enables full channel independence required for ASIL-B/C fault-tolerant designs without shared failure modes.

Can the MLX90316KGO-BCG-300-TU be reprogrammed in-system?

Yes, the MLX90316KGO-BCG-300-TU supports in-system programming via its SPI interface using the Melexis PTC-04 programmer. All configurable parameters-including output mode, transfer function (offset/gain/clamp), filter coefficients, diagnostic thresholds, and 40-bit ID-can be rewritten through VDD/VSS/OUT pins without removing the device from the PCB, enabling field calibration and firmware updates.
