NXP Semiconductors MPXV5004GC7U

Overview

MPXV5004GC7U from Freescale Semiconductor is a monolithic silicon piezoresistive gauge pressure sensor with 0–3.92 kPa (0–400 mm H₂O) full-scale range, ratiometric 0.2 V/kPa sensitivity, ±2.5% VFSS accuracy with autozero over 10 °C to 60 °C, and 5 VDC supply operation - designed for liquid level sensing in appliance and medical respiratory systems.

For engineers reviewing the MPXV5004GC7U datasheet, MPXV5004GC7U pinout, MPXV5004GC7U application, or MPXV5004GC7U equivalent, key selection criteria include its through-hole SOP-8 package, factory autozero capability, thermoplastic PPS housing, fluorosilicone gel isolation, and compatibility with microcontroller A/D inputs requiring low-drift analog pressure feedback.

Technical Context

The MPXV5004GC7U integrates a shear-stress strain gauge, on-chip temperature compensation circuitry, and signal conditioning onto a single die. Its output voltage follows V_OUT = V_S × [(0.2 × P) + 0.2] ±2.5% VFSS, where P is pressure in kPa and V_S is supply voltage (4.75–5.25 VDC).

It operates across 0 °C to +85 °C ambient, with offset voltage of 0.75–1.25 V at zero pressure and full-scale span of 3.92 V at 3.92 kPa. The device uses dry air as specified pressure media and requires mechanical autozero calibration to maintain ±2.5% accuracy under thermal cycling.

FAQ

What is the pressure range and output behavior of the MPXV5004GC7U?

The MPXV5004GC7U has a gauge pressure range of 0–3.92 kPa (0–400 mm H₂O). Its output voltage follows V_OUT = V_S × [(0.2 × P) + 0.2], producing 0.75–4.0 V over full scale at 5 V supply. At zero pressure, MPXV5004GC7U outputs 0.75–1.25 V; at 3.92 kPa, it delivers up to 3.92 V. This ratiometric behavior ensures consistent scaling even with supply variation.

Does the MPXV5004GC7U require external calibration or autozero circuitry?

The MPXV5004GC7U supports autozero functionality but does not include on-board storage - system-level autozero must be implemented externally. During initialization, the host MCU reads the MPXV5004GC7U output at known zero pressure and subtracts that value from subsequent readings. This compensates for mounting stress and thermal offset drift, enabling the specified ±2.5% VFSS accuracy over 10–60 °C.

What package type and mounting method does the MPXV5004GC7U use?

The MPXV5004GC7U uses a through-hole small outline package (Case 98ASB17759C), measuring 10.54 × 10.79 × 13.21 mm. It features eight leads with pins 1 and 5–8 designated DNC (do not connect), pin 2 as VS, pin 3 as GND, and pin 4 as VOUT. The package is designed for wave soldering or manual through-hole assembly, not surface mount.

Can the MPXV5004GC7U be used with pressure media other than dry air?

The MPXV5004GC7U is characterized and qualified for dry air as the pressure medium. Use with other media - including water vapor, cleaning agents, or saline - may degrade long-term reliability or cause drift. While fluorosilicone gel provides some environmental protection, Freescale explicitly states that non-dry-air media require factory consultation. For such applications, consider the MPVZ5004GW7U variant instead of the MPXV5004GC7U.

What is the maximum operating temperature and storage limit for the MPXV5004GC7U?

The MPXV5004GC7U has an operating temperature range of 0 °C to +85 °C ambient, with temperature-compensated accuracy specified from +10 °C to +60 °C. Its storage temperature range is –30 °C to +100 °C. Exceeding +85 °C during operation risks permanent degradation of the piezoresistive element and internal compensation circuitry, and is outside the validated specification for the MPXV5004GC7U.
