Product details
Overview
MLX90823GXP-BAD-306-SP from Melexis is a PCB-less, factory-calibrated relative pressure sensor with analog output, designed for automotive crankcase ventilation and vacuum monitoring. It delivers 0 to −1.0 bar pressure range, ±0.5% full-scale lifetime accuracy, ratiometric 0.5–4.5 V output, and operates from −40°C to 160°C. Its SMP7 package integrates MEMS, interface IC, and passive components for direct glue-mounting in harsh media environments.
For engineers reviewing the MLX90823GXP-BAD-306-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, calibrated transfer curve details, diagnostic configuration options, ASIL A safety compliance status, and OEM-validated EMC performance data specific to the BAD-306 variant.
Technical Context
The MLX90823GXP-BAD-306-SP implements a piezoresistive MEMS diaphragm with Wheatstone bridge transduction, coupled to a DSP-based CMOS interface IC featuring 16-bit microcontroller, EEPROM-programmable temperature compensation (up to third-order offset/gain), and configurable diagnostics. Its signal chain includes analog front-end filtering, ADC conversion, digital processing for linearization and clamping, and analog back-end output.
This variant is preconfigured for 0 to −1.0 bar relative pressure span with 0.5 V to 4.5 V ratiometric output, 1 ms default response time (0.4 ms fastest), and ±5 mBar typical pressure accuracy over temperature. Internal diagnostics include programmable over/under-voltage detection, broken connection monitoring, and pressure fault flagging via Upper/Lower Fault Band outputs.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90821GXP-BAD-306-RE | Same SMP7 package and 0 to −1.0 bar range, but lacks ASIL A development artifacts and diagnostic configurability; no EEPROM programmability | Targeted at cost-sensitive non-safety-critical applications; not qualified to ISO 26262 SEooC requirements | Select MLX90821GXP-BAD-306-RE only if functional safety certification and field calibration are unnecessary |
| MPXV7025GP | 0 to −25 kPa (−0.25 bar) range, 5 V supply, 0.2–4.8 V output; no integrated passives or diagnostics; uncalibrated at delivery | Requires external compensation, filtering, and calibration; limited to lower vacuum ranges and non-automotive environments | Choose MPXV7025GP only for prototyping or industrial vacuum gauges where full automotive qualification is not required |
Compared with MLX90821GXP-BAD-306-RE and MPXV7025GP, the MLX90823GXP-BAD-306-SP delivers certified ASIL A readiness, factory calibration with EEPROM programmability, integrated EMC-optimized passives, and validated harsh-media resistance - making it the only option qualified for production deployment in safety-critical automotive vacuum monitoring systems.

FAQ
What pressure range does the MLX90823GXP-BAD-306-SP measure?
The MLX90823GXP-BAD-306-SP measures a relative pressure range of 0 to −1.0 bar (i.e., vacuum from atmospheric up to 100 kPa below ambient). This is factory-programmed and fixed for this variant, with corresponding 0.5–4.5 V ratiometric analog output scaling linearly across the span.
Is the MLX90823GXP-BAD-306-SP calibrated before shipment?
Yes, the MLX90823GXP-BAD-306-SP is fully factory-calibrated across temperature and pressure, with compensation coefficients stored in on-chip EEPROM. No end-user calibration is required; the device delivers ±0.5% full-scale lifetime accuracy out-of-box, including temperature drift compensation up to third order.
Can the MLX90823GXP-BAD-306-SP be reprogrammed in-system?
Yes, the MLX90823GXP-BAD-306-SP supports in-system programming of diagnostics, fault thresholds, and pressure transfer curves using the Melexis PTC04 programming tool via its dedicated test pins. This enables customization of UV/OV detection levels, fault band polarity, and linearization parameters without changing hardware.
What is the operating temperature range of the MLX90823GXP-BAD-306-SP?
The MLX90823GXP-BAD-306-SP operates from −40°C to +160°C continuously, with short-duration tolerance up to +170°C for ≤10 minutes (max 20 hours cumulative over life). This rating is validated per AEC-Q100 Grade 0 and applies to the full specified pressure and output performance.
Does the MLX90823GXP-BAD-306-SP require external passive components?
No, the MLX90823GXP-BAD-306-SP integrates all required passive components (C1 = 47 nF, C2 = C3 = 100 nF) within its SMP7 package. The design eliminates external capacitors, simplifying layout, improving EMC immunity, and reducing bill-of-materials count for production modules.
