Product details
Overview
MLX90510GGO-BBA-100-SP from Melexis is a high-speed inductive absolute rotary position sensor IC designed for automotive motor control systems. It delivers differential sine/cosine analog outputs with ±0.36° electrical accuracy up to 240,000 e-rpm, 12-bit resolution, and operates across -40°C to 160°C. Its TSSOP-16 package supports through-shaft, end-of-shaft, and side-of-shaft configurations in BLDC/PMSM traction motors and electric power steering.
For engineers reviewing the MLX90510GGO-BBA-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, safety-certified use cases, and two confirmed alternative parts with documented functional differences.
Technical Context
The MLX90510GGO-BBA-100-SP integrates an LC oscillator (2.0–5.0 MHz) driving an external transmitting coil and processes signals from three receiving coils via analog front-end (AFE) with tri-amplifier common-mode suppression and automatic gain control (5 settings). Its digital signal processing includes phase tracking PLL, 16-point angular linearization, and DC offset compensation using EEPROM-programmable constants.
It implements ISO 26262 ASIL C SEooC compliance with built-in diagnostics for supply monitoring, sensor coil integrity, and output signal validity. The device supports programmable zero-angle adjustment and linear transfer characteristic tuning, with system propagation delay variation under ±120 ns and immunity to magnetic stray fields per ISO 11452-8.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Position Accuracy | ±0.36° el up to 240,000 e-rpm - enables precise rotor angle feedback for field-oriented control in high-speed PMSM motors without external calibration. |
| Output Type | Differential sine/cosine analog - provides noise-immune, ratiometric position signals compatible with standard resolver-to-digital converters or ADCs with differential input stages. |
| Supply Voltage | 4.5 V to 5.5 V - operates from regulated 5 V rail; supports overvoltage/reverse-polarity protection up to ±24 V for robust automotive ECU integration. |
| Propagation Delay | ±0.12 µs - ensures deterministic timing for real-time torque control loops with sub-microsecond latency stability. |
| Operating Temp | -40°C to 160°C - qualified for under-hood traction motor and EPS applications without derating or thermal shielding. |
| Resolution | 12-bit - delivers 0.0879° el quantization step, sufficient for 12-bit RDC interface or direct high-fidelity analog sampling. |

The MLX90510GGO-BBA-100-SP supports up to 240,000 e-rpm with ±0.36° electrical accuracy and extends to 660,000 e-rpm with ±0.66° accuracy. This performance is validated across its full operating temperature range (-40°C to 160°C) and applies specifically to the -100 variant's standard acceleration capability (±480,000 e-rpm/s). The MLX90510GGO-BBA-100-SP achieves this using its integrated LC oscillator and digital phase-tracking loop.
Does the MLX90510GGO-BBA-100-SP require external components for basic operation?
Yes, the MLX90510GGO-BBA-100-SP requires an external LC oscillator network (Tx coil + two CLCO capacitors), three receiving coils, and a 0.47 µF ceramic capacitor on VCAP. These are mandatory for signal excitation, reception, and supply stabilization. No external ADC, DAC, or microcontroller is needed for core position output, as the MLX90510GGO-BBA-100-SP generates fully conditioned differential sine/cosine analog signals.
How is functional safety implemented in the MLX90510GGO-BBA-100-SP?
The MLX90510GGO-BBA-100-SP implements ISO 26262 ASIL C SEooC compliance through on-chip diagnostics including supply voltage monitoring, LC oscillator amplitude/frequency checking, sensor coil integrity verification, and output signal validity detection. These mechanisms generate fault flags and support safe state indication without requiring external safety controllers - a core requirement for MLX90510GGO-BBA-100-SP deployment in EPS and e-brake systems.
Can the MLX90510GGO-BBA-100-SP be used with different coil configurations?
Yes, the MLX90510GGO-BBA-100-SP supports through-shaft, end-of-shaft, and side-of-shaft mechanical configurations via customizable external coil layouts. Its AFE and DSP are designed to process signals from any star-connected three-Rx-coil system driven by a single Tx coil. Coil inductance must fall within 40–500 nH (Rx) and 1–10 µH (Tx), as specified for MLX90510GGO-BBA-100-SP operation.
What is the role of the EEPROM in the MLX90510GGO-BBA-100-SP?
EEPROM in the MLX90510GGO-BBA-100-SP stores calibration and configuration data including DC offset compensation constants (DC01_CONST, DC12_CONST, DC20_CONST), 16-point linearization parameters (PEQ00–PEQ15), zero-angle adjustment (PHASE_OFFS), and AGC gain limits. This enables one-time programming during manufacturing or field calibration, ensuring MLX90510GGO-BBA-100-SP maintains accuracy across temperature and lifetime without host processor overhead.
