Product details
Overview
MLX90316KGO-BCG-200-TU from Melexis is an absolute rotary position sensor IC using Triaxis® Hall technology with integrated magneto-concentrator (IMC), delivering 12-bit angular resolution and programmable 0–360° angular range in TSSOP-16 dual-die package, designed for automotive throttle, pedal, and steering wheel position sensing under -40°C to +125°C.
For engineers reviewing the MLX90316KGO-BCG-200-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its pre-programmed analog output mode (PPA), dual-die redundancy, SPI-compatible serial interface capability, and ±700 mT magnetic flux tolerance - all validated for AEC-Q100 Grade 0 compliance in safety-critical motion feedback systems.
Technical Context
The MLX90316KGO-BCG-200-TU implements a monolithic Triaxis® sensing architecture with on-chip DSP processing of VX/VY magnetic field components, enabling contactless angular measurement via end-of-shaft dipole magnet rotation. Its dual-die TSSOP-16 configuration provides full hardware redundancy with isolated VDD1/VDD2, VSS1/VSS2, and independent output stages.
It supports three output modes - ratiometric analog, PWM, and 14-bit SPI serial - with factory-preprogrammed PPA (Pre-programmed Analog) configuration, including fixed linear transfer characteristic, clamping levels at 8% and 92%, and calibrated offset/gain. The device integrates 128 B EEPROM for user calibration data and features built-in diagnostics including broken VDD/VSS detection and watchdog timer.

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-000-TU | Single-die TSSOP-16, 16-bit resolution, SPI-only output, no PPA mode | Lacks dual-die redundancy and pre-programmed analog output; requires external calibration | Select when higher resolution and digital-only interface suffice, and functional safety redundancy is handled externally |
| AS5055A-DSOM | 14-bit contactless angle sensor, SOIC-16, SPI/I²C, no integrated IMC | Requires external flux concentrator; no built-in diagnostics or dual-die architecture | Choose for cost-sensitive non-automotive applications where AEC-Q100 and ASIL compliance are not required |
Compared with MLX90316KGO-BCG-200-TU, the MLX90363 offers higher resolution but sacrifices redundancy and out-of-box analog readiness, while the AS5055A lacks integrated magneto-concentration and failsafe diagnostics - making the MLX90316KGO-BCG-200-TU uniquely suited for pre-calibrated, safety-critical automotive rotary sensing.

FAQ
What output modes does the MLX90316KGO-BCG-200-TU support?
The MLX90316KGO-BCG-200-TU is pre-programmed in PPA (Pre-programmed Analog) mode, delivering a ratiometric analog output with clamped 8–92% VDD range. Though the underlying silicon supports PWM and SPI serial output, this specific variant is factory-configured for analog use only and cannot be reprogrammed to alternate modes without Melexis PTC-04 tool and EEPROM unlock sequence.
Is the MLX90316KGO-BCG-200-TU pin-compatible with other MLX90316 variants?
Yes, the MLX90316KGO-BCG-200-TU uses the TSSOP-16 package and shares identical pinout with all GO-coded MLX90316 variants, including MLX90316KGO-BCG-000-TU and MLX90316KGO-BCG-300-TU. However, differences in internal configuration (e.g., PPA vs. PPD vs. standard) mean firmware and calibration data are not interchangeable without reprogramming.
Does the MLX90316KGO-BCG-200-TU meet AEC-Q100 reliability standards?
Yes, the MLX90316KGO-BCG-200-TU is qualified to AEC-Q100 Grade 0 (-40°C to +150°C), with extended testing beyond standard Grade 1 requirements. Its dual-die TSSOP-16 construction, 128 B EEPROM endurance (>100k write cycles), and built-in diagnostics directly support ASIL-B/C system-level compliance in automotive ECUs.
How is redundancy implemented in the MLX90316KGO-BCG-200-TU?
Redundancy is implemented via two physically independent silicon dice in one TSSOP-16 package, each with dedicated VDD/VSS/VDIG rails, separate analog output stages (OUT1/OUT2), and independent SPI interfaces. The dice operate synchronously but can be monitored separately for cross-checking, enabling fail-operational behavior per ISO 26262.
Can the MLX90316KGO-BCG-200-TU be used without external calibration?
Yes - the "200" option code denotes Pre-programmed Analog (PPA) configuration, meaning the MLX90316KGO-BCG-200-TU ships with factory-calibrated linear transfer characteristics, clamping levels, and thermal compensation. No end-of-line calibration is required for basic angular measurement, though advanced users may refine parameters via Melexis PTC-04 and EEPROM access.
