NXP Semiconductors MP3V5050VC6U

Overview

MP3V5050VC6U from Freescale Semiconductor is a monolithic, signal-conditioned, gauge pressure sensor optimized for vacuum measurement from –50 kPa to 0 kPa on the P1 port, delivering a ratiometric analog output (0.06–2.9 V) with ±2.5% full-scale accuracy over 0 °C to 85 °C and temperature compensation from –40 °C to +125 °C. It features a patented silicon shear stress strain gauge and operates at 2.7–3.3 V supply with 7 mA typical current draw.

For engineers reviewing the MP3V5050VC6U datasheet, MP3V5050VC6U pinout, MP3V5050VC6U application, or MP3V5050VC6U equivalent, key selection considerations include its vacuum-rated gauge range, thermoplastic (PPS) SOP package, 1 ms response time, on-chip temperature compensation, and compatibility with microcontroller A/D interfaces requiring stable low-power analog sensing.

Technical Context

The MP3V5050VC6U integrates a piezoresistive silicon diaphragm with thin-film metallization and bipolar signal conditioning circuitry, including two-stage gain amplification and ground-reference shift circuitry. Its transfer function is V_OUT = V_S × (0.018 × P + 0.94), where P is pressure in kPa and V_S is supply voltage (3.0 V ±0.3 V).

It uses fluorosilicone gel encapsulation to isolate the die while transmitting pressure, and is calibrated for dry air media only. The device exhibits ±1.25 kPa maximum pressure error across its –50 to 0 kPa range and ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling.

Manufacturer

Freescale Semiconductor was a leading designer of embedded processors, analog, and sensor ICs, acquired by NXP Semiconductors in 2015. Its pressure sensor portfolio emphasized high-reliability, signal-conditioned transducers for automotive and industrial use.

The MP3V5050VC6U belongs to Freescale's MP3V series of monolithic silicon pressure sensors, engineered specifically for accurate, low-drift vacuum measurement in cost-sensitive, space-constrained systems requiring minimal external components.

FAQ

What pressure range does the MP3V5050VC6U measure?

The MP3V5050VC6U measures gauge pressure from –50 kPa to 0 kPa (vacuum relative to ambient on P2 port). It is calibrated and optimized for vacuum applications on the P1 port, with full-scale output occurring at –50 kPa. Operation outside this range causes saturation, and it is not rated for positive pressure or absolute measurement.

Is the MP3V5050VC6U compatible with 3.3 V microcontrollers?

Yes, the MP3V5050VC6U operates over 2.7–3.3 V DC supply and delivers a ratiometric analog output that scales with V_S. At 3.3 V, its output spans approximately 0.066–3.19 V, remaining within most 3.3 V ADC input ranges. No level-shifting is required, but decoupling (1.0 μF + 470 pF) is recommended per the datasheet.

Can the MP3V5050VC6U be used with liquids or aggressive gases?

No-the MP3V5050VC6U is qualified only for dry air as the pressure medium. Fluorosilicone gel encapsulation protects against moisture, but contact with liquids, solvents, or corrosive gases may degrade long-term reliability or alter calibration. For non-air media, consult NXP's application engineering team before deployment.

How many pins on the MP3V5050VC6U are functional?

Only three pins are functional on the MP3V5050VC6U: Pin 2 (VS), Pin 3 (GND), and Pin 4 (VOUT). Pins 1 and 5–8 are designated DNC (Do Not Connect) and must remain unconnected-no traces, vias, or solder mask openings should contact them to avoid parasitic coupling or mechanical stress.

Does the MP3V5050VC6U require external temperature compensation?

No-the MP3V5050VC6U includes fully integrated on-chip temperature compensation across –40 °C to +125 °C. Its output accuracy specification (±2.5% VFSS) already accounts for thermal effects over 0 °C to 85 °C, eliminating the need for external thermistors, lookup tables, or software correction algorithms in most applications.
