NXP Semiconductors MPVZ4006GW6U

Overview

MPVZ4006GW6U from Freescale Semiconductor is a fully integrated, on-chip signal-conditioned silicon pressure sensor with temperature compensation and factory calibration, designed for differential or gauge pressure measurement in the 0 to 6 kPa range. It delivers a ratiometric analog output (0.3–4.6 V at 5 V supply), features ±2.46% full-scale span accuracy with auto-zero, and is housed in a durable PPS thermoplastic small-outline surface-mount package (Case 1735-01). It is used in washing machine water level sensing and respiratory equipment.

For engineers reviewing the MPVZ4006GW6U datasheet, MPVZ4006GW6U pinout, MPVZ4006GW6U application, or MPVZ4006GW6U equivalent, key selection criteria include its 6 kPa full-scale range, 766 mV/kPa sensitivity, ±2.46% VFSS accuracy with auto-zero, operating temperature range of +10°C to +60°C, and compatibility with microcontroller A/D inputs without external signal conditioning.

Technical Context

The MPVZ4006GW6U integrates a piezoresistive silicon diaphragm, thin-film temperature compensation network, dual-stage gain amplification, and offset reference shift circuitry onto a single monolithic die. Its transfer function is Vout = VS × [(0.1533 × P) + 0.053], where P is pressure in kPa and VS is supply voltage.

It operates in differential or gauge configuration with P1 > P2 pressure bias, uses dry air as the specified pressure medium, and requires auto-zeroing post-installation to achieve specified accuracy. The gel die coat isolates wire bonds while transmitting pressure to the sensing element, and internal reliability testing is qualified for dry air only.

Key Specifications

Pinout & Package

MPVZ4006GW6U is packaged in a Small Outline Package (SOP), surface-mount, Case 1735-01, with an 8-pin lead frame and vertical port attachment. Pins 1, 5, 6, 7, and 8 are internal no-connects; only pins 2 (VS), 3 (GND), and 4 (Vout) are externally accessible.

FAQ

What is the pressure range and output behavior of the MPVZ4006GW6U?

The MPVZ4006GW6U has a full-scale pressure range of 0 to 6 kPa (0 to 612 mm H₂O) and produces a ratiometric analog output from 0.3 V to 4.6 V at a 5.0 V supply. Its transfer function is Vout = VS × [(0.1533 × P) + 0.053], where P is pressure in kPa. Output saturates outside the specified range, and linearity is maintained within ±2.46% VFSS when auto-zero is applied.

Does the MPVZ4006GW6U require external signal conditioning?

No, the MPVZ4006GW6U does not require external signal conditioning. It integrates on-chip temperature compensation, gain amplification, offset correction, and signal conditioning circuitry. The MPVZ4006GW6U outputs a ready-to-use analog voltage compatible with standard 5 V microcontroller ADC inputs, though a 0.01 µF bypass capacitor at Vout is recommended per Figure 3 of the datasheet.

What is the meaning of "auto-zero" for the MPVZ4006GW6U, and how is it implemented?

Auto-zero for the MPVZ4006GW6U refers to storing the zero-pressure output voltage at installation and subtracting that value from subsequent readings during operation. This compensates for mechanical stress-induced offset shifts. The MPVZ4006GW6U achieves ±2.46% VFSS accuracy only when auto-zero is performed; without it, accuracy degrades to ±5.0% VFSS. Implementation is purely system-level - no hardware modification of the MPVZ4006GW6U is needed.

What package type and mounting configuration does the MPVZ4006GW6U use?

The MPVZ4006GW6U uses Case 1735-01: a surface-mount small-outline package (SOP) with vertical port attachment. It has an 8-pin lead frame, but only pins 2 (VS), 3 (GND), and 4 (Vout) are functional; pins 1, 5–8 are internal no-connects. The package is molded in durable thermoplastic PPS and qualified for reflow soldering per J-STD-020.

Is the MPVZ4006GW6U compatible with media other than dry air?

The MPVZ4006GW6U is qualified and characterized 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 liquids, oils, or corrosive gases must be verified separately with NXP (formerly Freescale) and is not guaranteed for the MPVZ4006GW6U.
