NXP Semiconductors MPVZ5150GC7U

Overview

MPVZ5150GC7U from Freescale Semiconductor is a fully integrated, temperature-compensated and calibrated silicon piezoresistive pressure sensor with gauge pressure sensing (0–150 kPa), ratiometric 0.2–4.7 V analog output, ±0.5% VFSS offset stability over 1000-hour stress testing, and case 482C small-outline surface-mount package. It serves as a primary pressure transducer in microcontroller-based industrial control systems requiring stable analog input.

For engineers reviewing the MPVZ5150GC7U datasheet, MPVZ5150GC7U pinout, MPVZ5150GC7U application, or MPVZ5150GC7U equivalent, key selection criteria include its 150 kPa full-scale range, 4.7–5.25 V supply tolerance, 1 ms response time, 7 mA typical supply current, and media-resistant gel-encapsulated die for compatibility with dry air and select non-corrosive gases.

Technical Context

The MPVZ5150GC7U integrates a monolithic silicon shear-stress strain gauge with on-chip bipolar signal conditioning, thin-film temperature compensation, and factory calibration. Its transfer function is VOUT = VS × (0.006 × P(kPa) + 0.04), with temperature multiplier scaling error bands across –40°C to +125°C operating range.

It operates as a ratiometric device with 5.0 V nominal excitation, requires external decoupling (1.0 μF + 0.01 μF + 470 pF per Figure 3), and delivers a linear output spanning 4.5 V full-scale span (VFSS) at 25°C. Pins 1 and 5–8 are no-connects; only pins 2 (VOUT), 3 (GND), and 4 (VS) are functional.

Key Specifications

Pinout & Package

MPVZ5150GC7U uses a 4-pin small-outline package (Case 482C), surface-mount compatible, with fluorosilicone gel encapsulation protecting the die and wire bonds while transmitting pressure to the diaphragm. The pressure port is located on the side marked "Side with Port Attached" per Freescale's identification table.

FAQ

What is the pressure type and range supported by the MPVZ5150GC7U?

The MPVZ5150GC7U is a gauge pressure sensor with a full-scale range of 0–150 kPa (0–21.75 psi). It measures pressure relative to ambient atmospheric pressure using a single port (P1) exposed to the media, while the reference side (P2) is vented to atmosphere. This configuration is confirmed in Freescale's ordering information table and pressure-side identification guide for Case 482C.

Does the MPVZ5150GC7U require external signal conditioning or calibration?

No, the MPVZ5150GC7U does not require external signal conditioning or calibration. It integrates on-chip temperature compensation, gain adjustment, and factory calibration for both offset and full-scale output. The device delivers a ready-to-use 0.2–4.7 V ratiometric analog output directly compatible with standard microcontroller A/D inputs, as verified in Table 1 and the Transfer Function section of the datasheet.

What is the correct power supply decoupling network for the MPVZ5150GC7U?

The recommended decoupling network for the MPVZ5150GC7U consists of a 1.0 μF tantalum or ceramic capacitor, a 0.01 μF ceramic capacitor, and a 470 pF ceramic capacitor placed between VS and GND, as shown in Figure 3 of the datasheet. This three-capacitor arrangement suppresses high-frequency noise and ensures stable operation meeting all electrical specifications, especially during rapid pressure transients.

Which pins are functional on the MPVZ5150GC7U, and what are their roles?

The MPVZ5150GC7U has four physical pins, but only three are functional: Pin 2 is VOUT (analog output), Pin 3 is GND (ground reference), and Pin 4 is VS (supply input). Pins 1 and 5–8 are explicitly designated as no-connects in the internal schematic (Figure 1) and must remain unconnected on the PCB to avoid malfunction or damage.

Is the MPVZ5150GC7U compatible with media other than dry air?

The MPVZ5150GC7U is qualified and characterized for use with dry air as the pressure media. Freescale explicitly states that other media may adversely affect performance and long-term reliability due to potential chemical interaction with the fluorosilicone gel or sensing diaphragm. For non-dry-air applications, users must consult NXP (ex-Freescale) technical support to verify compatibility before deployment.
