Product details
Overview
MLX90293LDC-ADM-100-SP from Melexis is a programmable linear Hall position sensor IC in SOIC-8 package, delivering ratiometric analog, PWM or SENT (SAE J2716-2010) output with 12-bit resolution and ±0.5% full-scale linearity after calibration. It features 16-segment piecewise-linear position compensation and 6-segment thermal drift correction for sensitivity/offset, qualified to AEC-Q100 Grade 0 (−40 °C to +150 °C), and targets pedal position sensing in automotive powertrain systems.
For engineers reviewing the MLX90293LDC-ADM-100-SP datasheet, pinout, applications, or equivalent options, key selection considerations include its low-thermal-drift ADM-100 option, dual-output redundancy capability (in TSSOP-16 variant), SENT protocol compliance, open/short diagnostics, and programmable clamping thresholds for robust fault detection in safety-critical motion sensing.
Technical Context
The MLX90293LDC-ADM-100-SP implements a digital signal processing chain comprising a Hall plate, 12-bit ADC, RISC core, and configurable output driver supporting three standardized modes. Its transfer function is fully programmable via end-of-line calibration using Melexis tooling, enabling system-level nonlinearity compensation without custom magnetics.
Thermal drift mitigation uses independent 6-segment piecewise-linear correction for both sensitivity and offset across −40 °C to +150 °C, while position-domain compensation applies 16 segments over mechanical stroke or rotation angle. The SOIC-8 variant (LDC) integrates single-die architecture with integrated magneto-concentrator (IMC®) for enhanced field sensitivity and directional selectivity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Hall position sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Allegro A1324LLHLT-T | Fixed analog output only; no PWM or SENT; 10-bit resolution; no programmable thermal compensation. | Limited to basic analog interface systems; lacks diagnostic depth and protocol flexibility required for ASIL-B designs. | Select when cost-sensitive, non-safety-critical applications require only ratiometric voltage output with minimal calibration effort. |
| TDK NXP TLE4998C | PWM-only output; 13-bit resolution; integrated EEPROM but no SENT support; different pinout and package (SSO-8). | Suitable for PWM-input ECUs but incompatible with SENT-based diagnostic gateways; requires PCB redesign due to non-pin-compatible layout. | Choose where existing infrastructure mandates PWM timing compatibility and higher resolution is prioritized over multi-protocol flexibility. |
Compared with A1324LLHLT-T and TLE4998C, the MLX90293LDC-ADM-100-SP offers unique multi-protocol output configurability, factory-optimized thermal stability, and comprehensive diagnostics - making it the only option among the three qualified for ASIL-B pedal position sensing per ISO 26262 without additional hardware monitoring.

FAQ
What output protocols does the MLX90293LDC-ADM-100-SP support?
The MLX90293LDC-ADM-100-SP supports three configurable output protocols: ratiometric analog voltage, PWM with adjustable frequency and duty cycle range, and SENT (SAE J2716-2010) with Fast Channel (12-bit position) and Slow Channel (diagnostics, ID, temperature). All modes are selected and calibrated via Melexis programming tools during end-of-line setup - the MLX90293LDC-ADM-100-SP does not auto-detect protocol; configuration is stored in on-chip EEPROM and persists across power cycles.
How does the ADM-100 option differ from ADM-000 in the MLX90293LDC-ADM-100-SP?
The ADM-100 option in the MLX90293LDC-ADM-100-SP denotes factory-applied low-thermal-drift trimming: sensitivity and offset drift over temperature are reduced to <±0.1% FS/°C versus ±0.3% FS/°C for ADM-000. This is achieved through laser trimming of on-die resistors during final test - the MLX90293LDC-ADM-100-SP retains full programmability of its 6-segment thermal compensation table, but starts from a tighter baseline, reducing host MCU computational load in high-accuracy applications.
Can the MLX90293LDC-ADM-100-SP be used in dual-die redundant configurations?
No - the MLX90293LDC-ADM-100-SP specifically uses the "DC" package code, indicating the SOIC-8 single-die variant. Dual-die redundancy is only available in the TSSOP-16 package (GO code), such as MLX90293LGO-ADM-100-SP. The MLX90293LDC-ADM-100-SP shares the same core IP and calibration architecture but lacks the second die, diagnostic cross-check logic, and isolation resistance specifications defined for GO variants.
What diagnostics are implemented in the MLX90293LDC-ADM-100-SP?
The MLX90293LDC-ADM-100-SP implements open-circuit and short-circuit detection on the output pin, under-voltage lockout (MT4V threshold), over-voltage protection (clamping at +24 V), and broken-track diagnostics for VDD and VSS rails. Diagnostic status is reported either via dedicated DIAG pin output levels or embedded in the SENT slow channel - all diagnostics are hardware-accelerated and do not rely on firmware execution, ensuring deterministic response within 10 µs for critical faults.
Is the MLX90293LDC-ADM-100-SP pin-compatible with other Melexis Hall sensors?
No - the MLX90293LDC-ADM-100-SP has a unique SOIC-8 pinout optimized for its programmable architecture, differing from legacy Melexis parts like MLX90217 or MLX90242. Pin 1 is VDD (not GND), pins 2/3/6 are test interfaces (not NC), and pin 7 is VDIG (not NC or VDD). Substituting the MLX90293LDC-ADM-100-SP into an existing layout designed for another Melexis sensor will cause functional failure unless the schematic and PCB are revised to match the MLX90293LDC-ADM-100-SP pin mapping.
