NXP Semiconductors MPXHZ6250A6T1

Overview

MPXHZ6250A6T1 from Freescale Semiconductor is an integrated silicon absolute pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.3–4.9 V analog output over a 20–250 kPa (3.0–36 psi) range, operates from –40°C to +125°C, and achieves ±1.5% full-scale accuracy across 0°–85°C - ideal for engine control and LPG system monitoring.

For engineers reviewing the MPXHZ6250A6T1 datasheet, MPXHZ6250A6T1 pinout, MPXHZ6250A6T1 application, or MPXHZ6250A6T1 equivalent, key selection criteria include its super small outline package (Case 1317A-03), 1.0 ms response time, ±0.25%VFSS offset stability after 1000-hour stress testing, and compatibility with microcontroller ADC interfaces requiring stable, media-resistant sensing in harsh thermal environments.

Technical Context

The MPXHZ6250A6T1 integrates a piezoresistive silicon diaphragm with bipolar op-amp circuitry and thin-film resistor networks to deliver high-level analog output directly proportional to applied absolute pressure. Its internal architecture includes two gain stages, ground reference shift circuitry, and dedicated temperature compensation networks.

It is ratiometric to supply voltage (VS = 4.75–5.25 V), features gel die coating for environmental isolation, and is qualified for use with dry air as pressure media - non-air media require factory validation due to potential long-term reliability impact.

Key Specifications

Pinout & Package

MPXHZ6250A6T1 uses a Super Small Outline Package (SSOP), Case 1317A-03 - a surface-mount, durable thermoplastic (PPS) housing with 8 leads, where pins 1, 5, 6, 7, and 8 are internal no-connects and must remain unconnected in PCB layout.

The MPXHZ6250A6T1 belongs to Freescale's MPXHZ series of integrated absolute pressure sensors, engineered specifically for high-temperature accuracy and media resistance in engine management, alternative fuel systems, and ruggedized industrial instrumentation.

FAQ

What is the maximum rated pressure for MPXHZ6250A6T1?

The MPXHZ6250A6T1 has a maximum pressure rating of 1000 kPa, beyond which permanent damage may occur. Its specified operating range is 20–250 kPa, and output saturates outside this band. This overpressure margin allows for transient spikes in engine intake or LPG tank systems without sensor failure, provided exposure remains brief and within datasheet-defined limits.

Does MPXHZ6250A6T1 require external calibration?

No, MPXHZ6250A6T1 does not require external calibration. It is factory-calibrated for full-scale span and temperature-compensated across –40°C to +125°C. The device outputs a ratiometric analog voltage (0.3–4.9 V) directly usable by microcontroller ADCs. System-level calibration may still be applied for application-specific offsets, but the MPXHZ6250A6T1 itself ships with traceable, pre-programmed compensation.

Can MPXHZ6250A6T1 be used with media other than dry air?

MPXHZ6250A6T1 is qualified and characterized using dry air as the pressure medium. Use with other gases or liquids may affect long-term reliability and accuracy due to chemical interaction with the gel die coat or PPS package. Freescale explicitly advises contacting the factory for media compatibility validation before deploying MPXHZ6250A6T1 with non-air media in production systems.

What is the warm-up time specification for MPXHZ6250A6T1?

The MPXHZ6250A6T1 has a warm-up time of 20 ms - defined as the time required for output voltage to meet its specified accuracy after pressure stabilization. This fast settling enables rapid sampling in closed-loop control systems such as throttle position feedback or active LPG vapor pressure regulation, where latency must be minimized between pressure event and ECU response.

Is MPXHZ6250A6T1 pin-compatible with other MPXHZ series sensors?

MPXHZ6250A6T1 shares the same Case 1317A-03 SSOP package and pinout (VS, GND, VOUT, and five NCs) with other members of the MPXHZ6250A family, including MPXHZ6150A and MPXHZ6400A. However, pressure range, output scaling, and accuracy differ across variants - so while PCB layout is reusable, firmware scaling and error budgeting must be adjusted per model. MPXHZ6250A6T1 is not pin-compatible with MPXH6xxx or MPX5xxx series.
