MPXV4115V6U 개요
An integrated silicon pressure sensor (also called a piezoresistive pressure transducer or MEMS pressure sensor) is a monolithic device that converts applied pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped silicon strain gauges diffused onto a diaphragm. The MPXV4115V6U belongs to the broader sensor hierarchy: pressure sensor -> MEMS sensor -> transducer -> sensor IC -> semiconductor. Compared to ceramic capacitive or stainless-steel strain-gauge modules, integrated silicon sensors offer tighter factory calibration, lower per-unit cost at volume, and a smaller PCB footprint, at the trade-off of narrower temperature tolerance and limited media compatibility.
Key specifications include an operating pressure range of -16.68 PSI to 0 PSI (-115 kPa to 0 kPa), a maximum overpressure rating of -58.02 PSI (-400 kPa), an output span of 0.2 V to 4.6 V (approximately 38.3 mV/kPa), and a typical accuracy of ±1.5% Vfss. The on-chip temperature compensation flattens the output across the rated operating temperature range, and the integrated amplifier yields a low-impedance ratiometric output that interfaces directly to an MCU ADC. The -V suffix denotes the vacuum-gauge variant; non-V siblings cover 0 to +115 kPa positive gauge pressure.
Typical applications include medical respiratory monitoring, HVAC vacuum measurement, altimeter/barometric reference, industrial vacuum-pump diagnostics, and engine manifold absolute pressure (MAP) sensing when biased against atmosphere. The 8-SMD gull-wing package simplifies pick-and-place assembly and supports automated optical inspection, while the calibrated output removes counter design requirements and external trim potentiometers.
When designing with this part, place 0.1 uF decoupling close to the supply pin and route the analog output away from switching traces to preserve the 1.5% accuracy. The sensor is intended for clean, dry, non-corrosive gases; for liquid media or aggressive chemicals a protective media-isolated housing is required. For AEC-Q100 automotive engine control, choose the MPXV6115V6U upgrade sibling rather than this Part.

일반적인 애플리케이션

Medical Respiratory & CPAP Pressure Sensing
The MPXV4115V6U's -115 to 0 kPa vacuum range and calibrated 0.2-4.6 V analog output make it well-suited to medical respiratory equipment including CPAP/BiPAP machine vacuum feedback, spirometer flow-head pressure taps, and ventilator exhalation-valve diagnostics. With ±1.5% Vfss factory accuracy, no external trim network is needed at board bring-up, and the 5 V single-supply rail simplifies medical-isolated power designs. In one common circuit it sits between the patient-circuit manifold and an MCU ADC; the on-chip temperature compensation holds accuracy across body-temperature airflow variations without firmware lookup-table compensation. NXP family datasheet application note guidance recommends 0.1 uF supply decoupling and a low-impedance analog trace to preserve the ±1.5% accuracy spec.

HVAC Vacuum & Refrigeration Diagnostics
In HVAC service equipment, refrigeration evacuation, and vacuum-pump instrumentation, the MPXV4115V6U directly reads manifold vacuum levels during system evacuation and dehydration cycles. The -115 to 0 kPa span covers the typical 500 micron (67 Pa) target pull-down range when scaled through an MCU ADC and read against the 0.2-4.6 V transfer function. The integrated signal conditioning and 8-SMD gull-wing package allow a compact service-tool form factor with no external op-amp or trim potentiometer. Trade-off: the sensor is intended for clean dry gases only, so refrigerant-oil or aggressive-coolant streams require an upstream isolation chamber. Compared with discrete strain-gauge transducers, the integrated calibration removes the production-line trim step.
추천
Engine Crankcase & Manifold Vacuum Sensing
The MPXV4115V6U's -115 to 0 kPa range maps directly onto engine crankcase and brake-booster vacuum signals, where negative gauge pressure between 0 and -100 kPa is typical under idle and light-load conditions. The 0.2-4.6 V output drives a 5 V MCU ADC without an instrumentation front end, and the on-chip temperature compensation holds accuracy across -40C to +125C under-hood environments. For positive-manifold absolute pressure (MAP) above atmospheric, the MPXV6115V6U same-package sibling is the correct family member. Trade-off: the non-AEC-Q100 MPXV4115V6U is intended for industrial and non-automotive engine applications; for AEC-Q100 qualified engine control, select the automotive-qualified part variant.

Barometric Altimeter & Weather Instruments
When biased against a known vacuum reference or used to measure local pressure differential, the MPXV4115V6U provides a calibrated analog output suitable for handheld barometric altimeters, weather-station secondary sensors, and balloon-borne atmospheric probes. The 38.3 mV/kPa nominal scale factor over the -115 to 0 kPa span yields a usable dynamic range for differential barometric measurement with a single 5 V supply rail. The factory ±1.5% Vfss accuracy removes the per-unit trim step typical of uncalibrated MEMS die, and the 8-SMD package supports automated pick-and-place on compact weather-instrument PCBs. The -40C to +125C rating supports high-altitude low-temperature operation without derating.

Industrial Vacuum-Pump & Process Monitoring
Factory-automation skids, vacuum-conveying systems for pellet transfer, and pick-and-place vacuum-pick monitoring all require reliable -50 to -100 kPa vacuum feedback. The MPXV4115V6U's calibrated output interfaces directly to a 4-20 mA loop transmitter or industrial MCU with on-chip signal conditioning eliminating the instrumentation-amp front-end typical of bare-strain-gauge solutions. The integrated calibration across temperature holds the ±1.5% spec on the shop floor where ambient swings widely. The trade-off vs a capacitive ceramic alternative is narrower media compatibility (clean dry gases only); for liquid or particulate-laden processes an upstream isolation chamber is required.
추천
Portable Battery / Handheld Vacuum Tools
In handheld vacuum testers, blood-pressure cuff manometers, and battery-powered service tools, the MPXV4115V6U's single 5 V supply rail and low quiescent draw enable efficient battery/USB-power designs. The calibrated 0.2-4.6 V output feeds a low-power MCU ADC directly, removing the need for a separate instrumentation amp and shrinking the BOM versus discrete bridge-and-amp implementations. The 8-SMD gull-wing package supports high-density PCB layouts inside compact handheld enclosures. Trade-off: the part requires a regulated 5 V rail, so a boost converter is needed for designs running from a single Li-ion cell (3.0-4.2 V), adding BOM versus a 3.3 V native sensor.

설계 노트
Power the MPXV4115V6U from a regulated 4.75 V to 5.25 V rail. The analog output is ratiometric with VS, so any supply ripple or drift directly degrades the ±1.5% Vfss accuracy spec. Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VS pin (pin 3) and tie both GND pins to a low-impedance ground pour under the device. Estimated: the on-chip supply current is approximately 5-10 mA typical per family datasheet; verify with the actual datasheet figure for thermal budgeting.
Route the analog VOUT trace away from switching nodes, high-current traces, and clock lines. Use a guarded analog ground if the surrounding PCB carries noisy digital signals. The 8-SMD gull-wing package should be soldered with no-clean lead-free paste per the JEDEC J-STD-020 MSL classification; reflow profile should peak below 260 C to avoid damaging the on-chip calibration. Avoid mounting the sense aperture face-down where dust or condensate can accumulate.
Do not exceed the -400 kPa (-58.02 PSI) maximum overpressure rating; pump spikes or water hammer can permanently damage the silicon diaphragm. Do not expose the sense aperture to liquids, refrigerants, or corrosive gases - the integrated silicon sensor is intended for clean dry non-corrosive gases only, and direct liquid contact will shift calibration or destroy the part. For media isolation, plumb a flexible membrane or stainless isolation chamber upstream. Do not hot-plug the 5 V supply into a precharged output capacitance without a soft-start or current limit.
The ratiometric 0.2-4.6 V output assumes the MCU ADC uses the same 5 V rail as its reference; if the MCU ADC reference is 3.3 V, divide the sensor output with a resistive divider to preserve dynamic range. The output is bandwidth-limited by the on-chip compensation network; for fast transient pressure events (e.g., combustion knock sensing) the response time of approximately 1 ms may be insufficient - check the family datasheet response-time curve for the target pulse width.
