Product details
Overview
MLX90377GVE-ADB-230-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, delivering 12-bit SENT output with 3 μs tick time, linear stray-field immune operation, and ASIL-C functional safety capability for automotive pedal and throttle sensing. It operates from -40°C to +160°C with supply voltage up to 18 V and supports non-contact rotary/linear position measurement.
For engineers reviewing the MLX90377GVE-ADB-230-RX datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance (SAE J2716 APR2016), linear stray-field immunity, SMP-3 PCB-less single-mold packaging, ASIL-C safety qualification, and programmable transfer characteristic with up to 32-piecewise-linear points.
Technical Context
The MLX90377GVE-ADB-230-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angular (0–360°) or linear position decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning and advanced linearization using up to 32-point PWL tables.
This variant implements Linear Stray-Field Immune Mode (-2xx option code), uses SENT output with 3 μs tick time (not reprogrammable post-manufacture), and achieves ASIL-C compliance per ISO 26262 as a Safety Element out of Context - specifically for SENT, PWM, and SPC modes, with ASIL-B for analog mode.
Key Specifications

FAQ
What output protocol does the MLX90377GVE-ADB-230-RX support, and is it configurable?
The MLX90377GVE-ADB-230-RX supports SENT output with 3 μs tick time only - it is factory-programmed during production and cannot be reconfigured by the end user. This fixed configuration ensures deterministic timing and ASIL-C compliance without runtime variability. The MLX90377GVE-ADB-230-RX does not support PWM, analog, or SPC modes, as confirmed by its ADB-230 option code and datasheet Table 1.
What is the operating temperature range of the MLX90377GVE-ADB-230-RX, and how is it validated?
The MLX90377GVE-ADB-230-RX is rated for -40°C to +160°C ambient operation, verified per AEC-Q100 Grade 0 stress testing and qualified for continuous use at 160°C junction temperature. This range is validated across all electrical parameters in the datasheet's General Electrical Specifications section and applies to the SMP-3 package's thermal performance per Section 19.4.
Does the MLX90377GVE-ADB-230-RX include built-in decoupling capacitance?
Yes, the MLX90377GVE-ADB-230-RX in SMP-3 package integrates internal decoupling capacitance, eliminating the need for external VDEC capacitors. This is explicitly stated in Section 16.4 ("Wiring with the MLX90377 in SMP-3 Package (built-in capacitors)") and distinguishes it from SOIC-8 and TSSOP-16 variants that require external 100 nF ceramic capacitors.
How does the Linear Stray-Field Immune Mode function in the MLX90377GVE-ADB-230-RX?
The Linear Stray-Field Immune Mode (-2xx option code) in the MLX90377GVE-ADB-230-RX uses proprietary signal processing to suppress interference from orthogonal magnetic fields common in linear-motion applications such as pedal sensors. It is implemented in firmware and calibrated at factory - no external shielding or compensation circuits are required for operation in environments with nearby motors or solenoids.
What safety certification level does the MLX90377GVE-ADB-230-RX achieve, and for which output mode?
The MLX90377GVE-ADB-230-RX is ISO 26262 ASIL-C capable for SENT, PWM, and SPC output modes, and ASIL-B capable for analog mode - confirmed in the "Features and Benefits" section and Section 15 (Functional Safety). As a Safety Element out of Context, it provides documented fault handling time intervals and diagnostic coverage metrics specifically for SENT operation in the MLX90377GVE-ADB-230-RX variant.
