Product details
Overview
MLX91377GGO-ADB-011-RE from Melexis is a dual-die, AEC-Q100 Grade 0 qualified linear Hall effect sensor IC for high-accuracy absolute position sensing. It delivers 12-bit SPC output compliant with SAE J2716 APR2016, supports programmable piecewise-linear transfer characteristics (up to 32 segments), and operates across -40°C to +160°C in TSSOP-16 package - deployed in automotive steering torque and brake pedal sensors.
For engineers reviewing the MLX91377GGO-ADB-011-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its ASIL-C safety certification for SPC mode, inter-die synchronicity of ≤9.71 µs, 48-bit programmable ID, dual-die redundancy, and magnetic input span up to 100 mT with ±0.25% INL at 35°C.
Technical Context
The MLX91377GGO-ADB-011-RE integrates two independent Hall front ends, ADCs, DSPs, and ROM-based firmware in a single TSSOP-16 dual-die package. Its architecture enables real-time magnetic field decoding via on-chip signal conditioning and programmable LNR (linearization) with up to 32 PWL segments.
It supports two mutually exclusive output modes: SPC (Short PWM Code) with 1.5 µs tick time and SENT-compliant framing, or analog output with 12-bit resolution. Safety mechanisms include intelligent watchdog (TIWD = 4 ms), absolute watchdog (TAWD = 2.7 ms), and diagnostics test intervals of 3–4.5 ms per channel.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX91377GGO-ADB-080-RE | Analog output mode (12-bit), no SPC protocol support, identical dual-die TSSOP-16 package | Suitable for legacy analog ECU interfaces requiring voltage output instead of digital SPC frames | Select when system lacks SENT decoder hardware but requires same ASIL-B safety capability and dual-die redundancy |
| MLX91377GGO-ADB-120-RE | SPC output with 3.0 µs tick time (vs. 1.5 µs), same ASIL-C certification and PWL programming capability | Used where ECU trigger timing budget allows longer tick duration, reducing electromagnetic emissions | Choose for lower EMI-sensitive zones (e.g., near infotainment modules) while retaining full functional safety and accuracy |
Compared with MLX91377GGO-ADB-011-RE, the -080 variant trades digital protocol compatibility for analog interface simplicity and reduced MCU processing load, while the -120 variant relaxes timing constraints to ease EMC design - all three share identical dual-die architecture, temperature rating, and calibration infrastructure.

FAQ
What output protocol does the MLX91377GGO-ADB-011-RE support?
The MLX91377GGO-ADB-011-RE supports only Short PWM Code (SPC) output compliant with SAE J2716 APR2016, configured with 1.5 µs tick time. It does not support analog output or other protocols like SENT Fast/Slow Channel. This fixed SPC mode is defined by the ADB-011 option code and verified in Melexis' official ordering documentation.
Is the MLX91377GGO-ADB-011-RE certified for functional safety applications?
Yes, the MLX91377GGO-ADB-011-RE is certified as an ASIL-C Safety Element out of Context (SEooC) for SPC output per ISO 26262. This includes documented safety mechanisms such as intelligent watchdog (TIWD = 4 ms), diagnostics test intervals (DTIDIG = 4.5 ms), and fault handling time interval compliance - all validated in the official Melexis safety manual for this exact part number.
What is the magnetic input range specification for MLX91377GGO-ADB-011-RE?
The MLX91377GGO-ADB-011-RE supports a magnetic input span of up to 100 mT (|Bz|), as specified in Table 11 of the datasheet. This full-scale range enables high-resolution position measurement in demanding applications like steering torque sensing, where field gradients exceed 25 mT/mm and require minimal INL error (±0.25% max).
How is redundancy implemented in the MLX91377GGO-ADB-011-RE?
The MLX91377GGO-ADB-011-RE implements full hardware redundancy via two independent dies in one TSSOP-16 package, each with dedicated VDD1/VSS1/VDEC1 and VDD2/VSS2/VDEC2 pins. Inter-die synchronicity is guaranteed at ≤9.71 µs, and isolation resistance exceeds 4 MΩ - enabling cross-checking of SPC outputs for ASIL-C fault detection without external components.
Can the MLX91377GGO-ADB-011-RE be reprogrammed in-system?
Yes, the MLX91377GGO-ADB-011-RE supports in-system programming of its NVRAM via Programming through Connector (PTC), allowing field updates to PWL tables, SPC timing parameters, and 48-bit ID. PTC activation requires raising VDD above 6.3 V (VPROV0), and all programmable items are documented in Sections 11–13 of the official datasheet for this exact revision.
