MPXH6300AC6T1 Overview
A pressure sensor (also called a pressure transducer or piezoresistive sensor) is a device that converts an applied physical pressure into a proportional electrical signal. Absolute-pressure variants measure pressure referenced to a sealed vacuum cavity rather than to ambient air, which makes them ideal for applications requiring pressure readings independent of weather or altitude. The MPXH6300A series belongs to the hierarchy pressure sensor -> transducer -> sensor -> electronic component, and uses on-chip bipolar op-amp signal conditioning plus thin-film resistor networks for temperature compensation and calibration.
Key features include a 5.0 V single-supply operation, integrated temperature compensation from -40 C to +125 C, ratiometric analog output, and a top-port tube inlet sized for hose barb connections. The SOIC-8 surface-mount package with exposed top port supports pick-and-place assembly while keeping the pressure inlet accessible for media isolation. The on-chip calibration provides high accuracy across the automotive temperature range without external trimming.
Technically, the device uses a piezoresistive MEMS die suspended on a sealed reference cavity; under applied pressure the diaphragm deflects and the embedded Wheatstone bridge changes resistance, with on-chip amplification linearising the response. A 5 V supply produces a near rail-to-rail output swing that interfaces directly with most microcontrollers and ADCs without additional gain stages. Note: per verified web data, the operating pressure shown is 2.9 PSI to 44.09 PSI (20 kPa to 304 kPa), so a separate clinical low-pressure variant may be required for medical applications.
Typical applications include small-engine manifold absolute pressure (MAP) sensing, automotive engine control units, fuel-injected engine boost monitoring, HVAC pressure measurement, and industrial pneumatic control. The AEC-Q100 qualified variant supports underhood automotive deployments.
For best results, route the sensor port with short manifold tubing to minimise pneumatic lag, place a 100 nF decoupling capacitor directly at the supply pin, and protect the inlet from moisture and particulate ingress with an appropriate filter. Avoid touching the port during board cleaning because solvents and residue can degrade the seal.

Typical Applications
MPXH6300AC6T1 is suitable for 6 applications: Engine MAP / Boost Pressure Sensing, Small-Engine Fuel Injection Control, HVAC Refrigerant Line Pressure Monitoring, Industrial Pneumatic System Pressure Sensing, Altitude / Barometric Pressure Reference, Vehicle Suspension and Tire Pressure Telematics.
Engine MAP / Boost Pressure Sensing
The MPXH6300AC6T1's 20 kPa to 304 kPa absolute range aligns with manifold pressures from idle vacuum (~30 kPa) through naturally aspirated (~95 kPa) and moderately boosted turbo engines (up to 304 kPa), making it a drop-in MAP sensor for fuel-injected engines. The 0.3 V to 4.9 V output maps linearly across this span and feeds directly into an ECU ADC without additional gain, while the AEC-Q100 temperature range handles underhood conditions down to -40 C cold-start and +125 C soak. Reference designs typically place the sensor on the intake plenum with a short hose to limit pneumatic lag.
Recommended
Small-Engine Fuel Injection Control
Small two-stroke and four-stroke engines (motorcycles, scooters, handhelds) use the MPXH6300AC6T1 to measure absolute manifold pressure for fuel and ignition timing calculations. The 304 kPa upper limit covers peak boost at rev limiter, while the on-chip temperature compensation keeps accuracy stable across cold-start to hot-soak cycles. The top-side 0.13 inch tube port accepts a hose barb from the plenum without long manifold runners, and the 8-SOIC SMD package supports vibration-tolerant surface-mount assembly on the ECU PCB. Power saving comes from the rail-to-rail analog output that connects directly to the engine controller's ADC without instrumentation amplifiers.
Recommended
HVAC Refrigerant Line Pressure Monitoring
The MPXH6300AC6T1 monitors absolute pressure on the high and low sides of HVAC refrigerant lines, where operating pressures up to ~300 kPa (R-410A low-side) are common. The ratiometric 0.3 to 4.9 V output interfaces directly with the HVAC controller ADC, and the on-chip calibration eliminates the need for external trim. The top-port 8-SOIC form factor allows the sensor to be mounted on a manifold breakout board; proper isolation with a stainless-steel adapter or sealed hose prevents refrigerant contamination of the MEMS die. AEC-Q100 temperature qualification supports rooftop unit installations exposed to wide ambient swings.
Recommended
Industrial Pneumatic System Pressure Sensing
Compressed-air systems, pneumatic actuators, and vacuum-pump skid operators rely on the MPXH6300AC6T1 to monitor line pressure between 20 kPa (vacuum) and 304 kPa (workshop air). The ratiometric output works with simple industrial controller ADCs at 5 V I/O, while the 8-SOIC package provides vibration tolerance in factory environments. The 0.13 inch top-side port adapts to standard pneumatic hose barbs; a particulate filter upstream prevents dust ingestion. The -40 to +125 C operating temperature covers unheated warehouse and outdoor pneumatic installations.
Recommended
Altitude / Barometric Pressure Reference
For drones, weather stations, and handheld instruments, the MPXH6300AC6T1 provides an absolute pressure reference corresponding roughly to sea level (101 kPa) through ~10 km altitude (~26 kPa). The on-chip linearisation and temperature compensation produce a near-direct altitude estimate with simple data-sheet transfer-function math; ratiometric output simplifies 3.3 to 5 V analog signal-chain design. The 8-SOIC top-port footprint is friendly to miniature weather-station PCBs where a vertical manifold port improves air-pressure equalisation.
Recommended
Vehicle Suspension and Tire Pressure Telematics
Telematics and tire-pressure monitoring derivatives of the MPXH6300AC6T1 measure absolute pressure in suspension chambers and pneumatic systems where peak pressure stays below 304 kPa. The AEC-Q100 grade tolerates underchassis thermal cycles, and the 8-SOIC top-port footprint mounts on a sealed manifold PCB with a flexible hose from the chamber. The 0.3 to 4.9 V ratiometric output interfaces with the telematics module ADC, while the calibrated linearisation reduces in-vehicle processor load compared to uncompensated transducers.

Key Differentiators
- Calibrated temperature compensation across -40 C to +125 C eliminates external circuitry (vs MPXHZ6400A)
- Top-side tube port integrates pressure inlet into standard SMD PCB assembly (vs Bonsai-style piezo modules)
- Ratiometric 0.3 to 4.9 V output interfaces directly with 5 V ADCs (vs MPXV6115V (different NXP family))
Design Notes
Place a 100 nF ceramic decoupling capacitor within 5 mm of the Vs (pin 3) and GND (pin 2) leads to suppress supply-borne noise from the ECU rail; add a 1 uF tantalum or ceramic bulk capacitor on the same 5 V node if the upstream regulator has any inductive output impedance. Route the analog output (pin 1) with short traces guarded by ground on either side to keep injected switching-noise floor low. The 8-SOIC top-port footprint requires a keep-out under the part so the tube port is unobstructed, and pads should be no-clean lead-free per the NXP recommended reflow profile. Verify solder paste stencil apertures are sealed off under the port opening to prevent solder balls from bridging into the inlet.
Avoid pointing the 0.13 inch top port downward where liquids or condensation could accumulate inside the MEMS cavity; design the pneumatic circuit so liquid condensate drains away from the sensor inlet. Apply a hydrophobic PTFE membrane filter (e.g., 1 um pore, 13 mm diameter) over the tube inlet when used in industrial harsh environments or outdoor pneumatic lines. Use a manifold housing that thermally isolates the sensor from the engine block when measuring intake pressure, otherwise heat conducted through the metal hose barb will shift the on-chip calibration. Never subject the device to overpressure beyond the rated maximum - NXP specifies a maximum overpressure burst rating in the datasheet that must not be exceeded during pneumatic transients (e.g., test-fixture bursts).
The ratiometric 0.3 V to 4.9 V output is designed for direct connection to a microcontroller 5 V ADC or a 5 V-grade instrumentation amplifier. Add a unity-gain op-amp buffer (e.g., TLV9064 or MCP6002) only when the downstream ADC has source-impedance sensitivity, since the sensor output impedance is in the single-digit kohm range - capacitive loading above 1 nF on the output pin must be avoided because it interacts with the sensor output stage. Estimate: at 10 nF load the output rolls off starting near 1.6 kHz. If EMI is a concern (automotive ECU environment), place a 10 ohm series resistor at the output plus a 10 nF cap to ground to form a low-pass filter cutting EMI above 1.6 MHz while preserving DC accuracy.
