MP3V5050VC6U - -50 to 0 kPa Vacuum Pressure Sensor 8-SMD | STMicroelectronics
MPN： MP3V5050VC6U ✓ 啟用中MP3V5050VC6U 概覽
Key specifications derived from the manufacturer datasheet include a 3 V supply, an analog output span of 0.06 V to 2.82 V that is ratiometric to the supply, 5% accuracy across 0C to 85C, and a -40C to +125C operating range. The vented axial port design references atmospheric pressure on the back side so the output indicates vacuum with respect to ambient.
An LDO, or low-dropout linear regulator, is a class of analog power-management IC that maintains a tightly regulated output even when the input voltage is only slightly above the desired rail. Pressure sensors sit higher in the signal-conditioning chain (sensor -> analog front-end -> ADC -> MCU), but they share the same end goal as LDOs: convert a real-world physical quantity or voltage into a clean, low-noise DC level that downstream circuitry can digitize. In this hierarchy the MP3V5050V family belongs to MEMS sensors -> pressure sensors -> signal-conditioned pressure transducers.
The sensor combines advanced micromachining, thin-film metallization, and bipolar semiconductor processing. On-chip op-amp circuitry and laser-trimmed thin-film resistor networks provide a high-level analog output proportional to applied vacuum, simplifying the designer's analog front end. The MP3V5050VC6U is part of the MPxx5050 family, of which the VC6U variant is the vacuum-port SOP 8 gull-wing tape-and-reel part.
Typical applications include HVAC vacuum monitoring, medical vacuum equipment, altimeters and barometric aids, weather stations, and industrial process control where a compact, calibrated, conditioned vacuum signal is needed. Designers also use the part in pneumatic systems that require a ratiometric analog output that follows the supply.
A design tip when using this part: rely on the ratiometric analog output by using the same 3.0 V reference for the ADC and the sensor. This cancels supply drift and preserves the calibrated accuracy. Place a 1 nF to 100 nF decoupling capacitor close to VDD and avoid kinking or torquing the port tube.

典型應用
MP3V5050VC6U 適用於 6 應用s: HVAC Vacuum Monitoring, Medical Vacuum Equipment, Altimeter and Barometric Aid, Industrial Process Control, Pneumatic System Monitor, Automotive Vacuum Assist Sensing.
HVAC Vacuum Monitoring
The MP3V5050VC6U provides a calibrated, ratiometric 0.06 V to 2.82 V analog signal for the -50 to 0 kPa vacuum range typically seen in HVAC refrigerant evacuation and vacuum pump monitoring. Its on-chip temperature compensation and 5% accuracy from 0C to 85C let designers drop the conditioned signal directly into an MCU ADC without extra analog front-end circuitry, simplifying the BOM. The vented axial port references atmospheric pressure on the back side so readings remain gauge-correct regardless of ambient temperature swings in mechanical rooms.
推薦
Medical Vacuum Equipment
For medical suction, drainage, and dental vacuum systems, the MP3V5050VC6U delivers a factory-calibrated vacuum reading that meets the -50 to 0 kPa span common to clinical suction lines. The 5% accuracy and integrated signal conditioning reduce calibration overhead in production and support IEC 60601-style environmental envelopes. The 8-SMD top-port package fits compact handheld consoles where PCB real estate is at a premium and the vented axial port can be plumbed directly to the suction line.
推薦
Altimeter and Barometric Aid
When used in weather stations or backup altimeters, the MP3V5050VC6U offers a stable vacuum reading referenced through its vented port, allowing derivation of atmospheric altitude. The ratiometric 3 V output pairs well with low-power MCUs and SAR ADCs without requiring a precision reference. Combined with a temperature sensor, the same board can synthesize a basic barometric/weather node for outdoor IoT endpoints.
推薦
Industrial Process Control
In process-control panels monitoring vacuum levels in pick-and-place suction, vacuum chucks, and packaging machines, the MP3V5050VC6U provides a robust conditioned analog signal directly proportional to vacuum. The surface-mount 8-SMD module with top-port access simplifies panel plumbing and the -40C to +125C operating range tolerates factory-floor temperatures. The factory-calibrated 5% accuracy is acceptable for trend logging and threshold alarms common on SCADA dashboards.
推薦
Pneumatic System Monitor
The MP3V5050VC6U is well suited to pneumatic lines where the vacuum (sub-atmospheric) side must be monitored for leak detection and pump health. Its 0.06 V to 2.82 V ratiometric span makes threshold detection easy with a simple comparator or ADC, and the on-chip calibration removes the cost of a manual trim step. Combined with a small OLED or LED bar graph, technicians can read the vacuum level directly on the equipment without external instrumentation.
推薦
Automotive Vacuum Assist Sensing
While the MP3V5050VC6U itself is not AEC-Q100 qualified, the same family of signal-conditioned pressure sensors is widely used in non-safety automotive sub-systems such as vacuum brake assist monitoring, fuel pressure trend logging, and HVAC recirculation diagnostics. Designers must verify AEC-Q100 requirements separately if the application is safety-critical. The 3 V ratiometric output mates easily with automotive MCU ADC channels already powered from a 3.3 V rail.

主要差異化特點
- Calibrated vacuum-range output (0.06 to 2.82 V at VDD=3 V) (對比MP3V5050GC6T1)
- Same die as MP3V5050VC6T1 with multi-distributor stock (對比MP3V5050VC6T1)
- 8-SMD top-port module with vented axial tube (對比MP3V5050DP)
設計說明
Power the MP3V5050VC6U from a clean 3.0 V rail and share that same rail with the ADC reference input. Because the output is ratiometric to VDD, supply noise or drift directly modulates the output, so a low-noise LDO (for example an STMicroelectronics LD39050PU33R) and a 100 nF X7R decoupling cap placed within 3 mm of the VDD pin are essential for preserving the factory 5% accuracy.
Keep the vented port free of obstructions and avoid torquing or kinking the axial tube during assembly. Maintain a 2 mm keep-out around the port on the PCB for tubing clearance, and route VDD and Vout as differential/guard traces away from switching converters to prevent EMI coupling into the conditioned analog path.
Do not apply positive pressure above 50 kPa to the vented port - the part is calibrated only for the -50 to 0 kPa vacuum range and overpressure can permanently damage the diaphragm. Also avoid contamination of the port with oil or water; use a 0.5 micron inline filter if the upstream line may carry particulates.
