Product details
Overview
MLX90377GGO-ADB-210-TU from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary or linear position sensing using Bx/By/Bz field components. It delivers 12-bit analog or PWM output in Linear Stray-Field Immune Mode, operates from -40°C to 160°C, and supports ASIL-B functional safety for analog mode. Used in throttle and pedal position sensing where stray-field immunity and high-speed response are critical.
For engineers reviewing the MLX90377GGO-ADB-210-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed output timing (≤1.5 ms latency), validated stray-field immune calibration, and real-world automotive use cases with documented accuracy specs.
Technical Context
The MLX90377GGO-ADB-210-TU implements Triaxis® Hall sensing with on-chip DSP-based signal conditioning and programmable piecewise-linear transfer characteristics (up to 32 segments). Its Linear Stray-Field Immune Mode (-2xx option code) uses dedicated magnetic front-end configuration and enhanced filtering to reject orthogonal interference fields while maintaining ±0.3° angular accuracy over full temperature range.
This variant features dual-die TSSOP-16 packaging with isolated VDD1/VSS1 and VDD2/VSS2 domains, enabling redundant operation and internal isolation resistance ≥4 MΩ. Output is configurable only as analog ratiometric or PWM - SENT and SPC modes are disabled per ADB-210 firmware configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-310-TU | Standard/Legacy Mode; same TSSOP-16 package but no stray-field immunity; higher susceptibility to orthogonal B-field interference | Suitable for shielded environments (e.g., enclosed actuators); lacks linear stray-field calibration and filtering | Select when cost sensitivity outweighs field immunity needs and magnetic environment is controlled |
| MLX90377GVS-ADB-210-TU | DMP-4 package (PCB-less dual-mold); identical ADB-210 firmware and stray-field immune mode; 4-pin footprint vs. 16-pin TSSOP | Targeted for space-constrained modules (e.g., motor-integrated sensors); requires different PCB layout and decoupling | Choose for ultra-compact designs where board area is limited and thermal dissipation via leadframe is acceptable |
Compared with MLX90377GGO-ADB-210-TU, the ADB-310 variant trades stray-field immunity for lower cost in benign environments, while the DMP-4 ADB-210 offers identical sensing performance in a 4-pin surface-mount package - enabling direct integration into actuator housings without PCB routing.

FAQ
What output protocols does the MLX90377GGO-ADB-210-TU support?
The MLX90377GGO-ADB-210-TU supports only analog ratiometric and PWM output modes, as defined by its ADB-210 option code. SENT and SPC protocols are disabled in firmware and cannot be enabled via programming. This configuration prioritizes high-speed analog fidelity and stray-field immunity over serial communication bandwidth.
How is stray-field immunity implemented in the MLX90377GGO-ADB-210-TU?
The MLX90377GGO-ADB-210-TU achieves Linear Stray-Field Immunity through factory-trimmed magnetic front-end biasing, dedicated DSP filtering algorithms, and hardware-level rejection of orthogonal B-field components. It maintains ±0.3° angular accuracy even when exposed to ±10 mT interfering fields perpendicular to the sensing axis - verified per ISO 11452-8.
What is the pin compatibility status between MLX90377GGO-ADB-210-TU and other MLX90377 variants?
The MLX90377GGO-ADB-210-TU uses the TSSOP-16 package and shares identical pinout and electrical interface with all other GO-code variants (e.g., ADB-310, ADB-230). However, firmware differences mean output behavior, diagnostic flags, and internal calibration are not interchangeable - each option code requires matching host software.
Does the MLX90377GGO-ADB-210-TU support functional safety certification out of the box?
Yes, the MLX90377GGO-ADB-210-TU is certified as a Safety Element out of Context (SEooC) per ISO 26262, with ASIL-B capability for analog output mode. It includes built-in diagnostics such as broken-wire detection on VDD/VSS, watchdog timers, and memory ECC - all documented in Melexis' FS manual MLX90377-FS-001.
What decoupling capacitors are required for stable operation of the MLX90377GGO-ADB-210-TU?
The MLX90377GGO-ADB-210-TU requires two 100 nF X7R ceramic capacitors: one between VDEC1 and VSS1, and another between VDEC2 and VSS2. These must be placed within 2 mm of their respective pins, with low-ESR construction and rated for ≥16 V. Additional bulk capacitance (≥10 µF tantalum) is recommended at the main VDD input.
