NXP Semiconductors MPXV4006GC6U

Overview

MPXV4006GC6U from Freescale Semiconductor is a fully integrated, temperature-compensated, factory-calibrated silicon piezoresistive pressure sensor in a surface-mount small-outline package (Case 482A-01) with axial port configuration. It delivers a ratiometric analog output of 0.2–4.7 V over a 0–6 kPa differential pressure range, operates from 4.75–5.25 V supply, and achieves ±5.0% full-scale span accuracy across –10°C to +60°C ambient, targeting microcontroller-based medical airflow monitoring and HVAC differential pressure sensing.

For engineers reviewing the MPXV4006GC6U datasheet, MPXV4006GC6U pinout, MPXV4006GC6U application, or MPXV4006GC6U equivalent, key selection criteria include its axial-port mechanical interface, N/C pin isolation requirements, on-chip signal conditioning eliminating external op-amps, and factory auto-zeroed offset stability critical for low-pressure transduction in portable diagnostic devices.

Technical Context

The MPXV4006GC6U integrates a monolithic shear-stress strain gauge with thin-film temperature compensation circuitry, bipolar gain stages, and ground-reference shift logic onto a single silicon die. Its output transfer function is defined as Vout = VS × [(0.1533 × P) + 0.045] ± 5% VFSS, where VS is supply voltage and P is applied differential pressure in kPa.

It uses fluorosilicone gel encapsulation to isolate wire bonds and die while transmitting pressure to the silicon diaphragm, and requires dry air as the pressure medium to maintain long-term reliability and specified accuracy. The device is explicitly rated for P1 > P2 operation, with the axial port side designated as the Pressure (P1) side per Freescale's identification table.

Key Specifications

Pinout & Package

MPXV4006GC6U uses Case 482A-01: surface-mount small-outline package (10.54 × 10.54 × 5.38 mm) with axial port and notch-marked Pin 1. Pins 1, 5, 6, 7, and 8 are internal no-connects and must remain unconnected in PCB layout.

FAQ

What is the pressure media compatibility of the MPXV4006GC6U?

The MPXV4006GC6U is qualified for use with dry air as the pressure medium. Freescale explicitly states that other media may adversely affect long-term reliability and performance. Internal qualification testing was conducted only for dry air; media compatibility for gases like O₂ or CO₂, or liquids, requires factory consultation and is not guaranteed for MPXV4006GC6U.

Does the MPXV4006GC6U require external zero-pressure calibration after mounting?

Yes-the MPXV4006GC6U requires system-level auto-zeroing after mechanical installation. Due to mounting-induced stress, the factory zero is not preserved post-assembly. Users must sample Vout at zero differential pressure and subtract that value digitally during operation to achieve the specified ±5% VFSS accuracy, as noted in Note 5 of the operating characteristics table.

What is the significance of the "C" in MPXV4006GC6U?

The "C" in MPXV4006GC6U denotes the axial port configuration per Freescale's ordering nomenclature. As confirmed in the Pressure (P1)/Vacuum (P2) Side Identification Table, MPXV4006GC6U uses Case 482A and has the pressure port located axially on the side with the port attached-distinguishing it from non-ported variants like MPXV4006G6U and side-port versions like MPXV4006GC7U.

Can the MPXV4006GC6U operate outside its specified temperature range?

No-the MPXV4006GC6U has a defined operating temperature range of –10°C to +60°C. While storage temperature extends to –30°C to +100°C, operation outside the –10°C to +60°C ambient range voids the ±5% VFSS accuracy guarantee and risks unpredictable offset drift or signal nonlinearity due to uncharacterized thermal effects on the on-chip compensation network.

What decoupling capacitance is recommended for the MPXV4006GC6U VS pin?

Freescale recommends a 1.0 µF bulk capacitor plus a 0.01 µF ceramic capacitor placed as close as possible to the VS pin (Pin 2) and GND (Pin 3), per Figure 3 in the datasheet. This dual-capacitor network suppresses both low-frequency supply ripple and high-frequency noise, ensuring stable biasing of the internal gain stages and preventing output instability in microcontroller-interfaced systems.
