Product details
Overview
MPVZ5050GW7U from Freescale Semiconductor is a fully integrated, temperature-compensated and factory-calibrated silicon piezoresistive pressure sensor in a small-outline package (Case 1560-02), delivering a ratiometric 0.2–4.7 V analog output over a 0–50 kPa gauge pressure range, with ±2.5% full-scale accuracy from 0°C to 85°C, designed for microcontroller-based automotive HVAC, medical pneumatic controls, and industrial process monitoring.
For engineers reviewing the MPVZ5050GW7U datasheet, MPVZ5050GW7U pinout, MPVZ5050GW7U application, or MPVZ5050GW7U equivalent, key selection considerations include its differential/gauge sensing architecture, 1.0 ms response time, 7.0 mA typical supply current at 5.0 V, fluorosilicone-gel-isolated die, and strict dry-air media compatibility requirement.
Technical Context
The MPVZ5050GW7U integrates a patented silicon shear-stress strain gauge with on-chip bipolar signal conditioning, dual-stage gain amplification, and temperature compensation circuitry spanning –40°C to +125°C. Its transfer function Vout = VS × (0.018 × P + 0.04) is ratiometric to supply voltage, enabling direct A/D interfacing without external scaling.
It operates as a gauge-pressure transducer with defined P1 (pressure side, fluorosilicone-coated) and P2 (vacuum/reference side) ports, requiring the decoupling network shown in Figure 4 (1.0 µF + 0.01 µF + 470 pF) to meet specified electrical performance, and exhibits ±0.5% VFSS offset stability after 1000-hour pulsed pressure/temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–50 kPa gauge (0–7.25 psi); defines usable linear sensing span with saturation beyond limits |
| Output Voltage | 0.2–4.7 V at VS = 5.0 V; ratiometric analog output directly compatible with 5 V ADC references |
| Accuracy | ±2.5% of full-scale span (VFSS) over 0°C to 85°C; includes linearity, hysteresis, TcOffset, and TcSpan contributions |
| Response Time | 1.0 ms (10% to 90%); enables real-time pressure tracking in dynamic pneumatic systems |
| Supply Current | 7.0 mA typical at 5.0 V; determines low-power system budget for battery-operated sensors |
| Operating Temp | –40°C to +125°C; supports under-hood automotive and industrial ambient environments |
| Max Pressure | 200 kPa absolute; mechanical overpressure limit before permanent diaphragm deformation |
Pinout & Package
MPVZ5050GW7U uses Case 1560-02 - an 8-pin small-outline package with axial port 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 | VS | Positive supply input (4.75–5.25 V); powers all on-die circuitry and sets output scale ratiometrically |
| Pin 3 | GND | Analog ground reference; must be low-impedance and shared with ADC reference ground |
| Pin 4 | Vout | Conditioned analog output; requires RC filtering per Figure 4 to meet noise and bandwidth specs |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over –40°C to +125°C operating range; eliminates need for external thermistor or software correction |
| Patented silicon shear-stress gauge | Monolithic micromachined element providing high repeatability and low hysteresis vs. conventional piezoresistive bridges |
| Fluorosilicone gel isolation | Protects wire bonds and die surface from moisture and chemical exposure while transmitting pressure signal reliably |
| Ratiometric output architecture | Output scales linearly with supply voltage; simplifies system-level calibration when using shared 5 V rail |
| Factory calibration | Zero and span trimmed at production; delivers plug-and-play accuracy without end-user trimming |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5050GP | Same 0–50 kPa range and SOIC-8 package, but unported, non-gel-isolated; lacks P1/P2 side definition and media protection | Suitable only for clean, dry air in controlled lab environments; not rated for humid or chemically aggressive media | Select MPX5050GP only if cost sensitivity outweighs long-term reliability in harsh conditions |
| SSCDANT050PGAA3 | 0–50 psi (345 kPa) range, digital I²C output, 3.3 V operation; higher full-scale range and integrated ADC, but no ratiometric analog output | Requires microcontroller with I²C interface and firmware support; unsuitable for direct analog A/D systems | Choose SSCDANT050PGAA3 when digital communication, lower supply voltage, or higher overpressure tolerance are prioritized |
Compared with MPX5050GP and SSCDANT050PGAA3, the MPVZ5050GW7U uniquely combines gel-isolated gauge sensing, axial porting, ratiometric analog output, and validated dry-air media compatibility - making it the preferred choice for automotive and medical pneumatic systems demanding long-term stability and environmental robustness.

FAQ
What is the pressure port configuration of the MPVZ5050GW7U?
The MPVZ5050GW7U features an axial port with vertical port attachment (Case 1560-02), where the P1 (pressure) side is identified by the fluorosilicone-gel-coated surface and the P2 (vacuum/reference) side is the opposite face. It is a gauge-pressure sensor intended for P1 > P2 operation using dry air as the pressure medium.
Does the MPVZ5050GW7U require external signal conditioning?
No, the MPVZ5050GW7U includes fully integrated signal conditioning, temperature compensation, and factory calibration. It delivers a ready-to-use 0.2–4.7 V ratiometric analog output. However, Freescale recommends the decoupling/filtering network from Figure 4 (1.0 µF, 0.01 µF, and 470 pF) to ensure compliance with electrical specifications and noise immunity.
What is the meaning of "±2.5% VFSS" accuracy for the MPVZ5050GW7U?
"±2.5% VFSS" means the total error - including linearity, temperature hysteresis, pressure hysteresis, TcSpan, TcOffset, and nominal variation - does not exceed ±2.5% of the full-scale span (VFSS = VFSO − Voff ≈ 4.5 V) over 0°C to 85°C. This is a guaranteed maximum error band, not a typical value, and applies to the MPVZ5050GW7U as shipped.
Can the MPVZ5050GW7U be used with media other than dry air?
No - Freescale explicitly states that MPVZ5050GW7U characterization and reliability testing were performed using dry air. Other media may degrade performance or long-term reliability. For non-dry-air applications, consult NXP (successor to Freescale) for qualified alternatives or custom qualification guidance before deploying the MPVZ5050GW7U.
What is the warm-up time specification for the MPVZ5050GW7U?
The MPVZ5050GW7U has a maximum warm-up time of 20 ms - defined as the time required after stabilized pressure application for the output voltage to settle within its specified accuracy band. This enables fast system initialization in time-critical applications such as respiratory cycle detection or HVAC damper response.
