MP3H6115A6T1 概述
An absolute pressure sensor is a transducer that measures pressure referenced to a perfect vacuum sealed inside the reference cavity of the die, as opposed to gauge or differential sensors that reference ambient atmosphere. Absolute sensors are the correct choice for applications where the system must remain accurate regardless of environmental conditions, such as altitude measurement in portable weather stations or barometric correction in GPS receivers. Within the broader sensor hierarchy, the MP3H6115A6T1 sits at the integrated pressure transducer (sensor + signal conditioner + temperature-compensator + output driver) layer above raw MEMS die and below application-level signal processing.
Key features include a male tube pressure port (0.13 inch / 3.3 mm diameter) for direct pneumatic connection, durable thermoplastic (PPS) surface-mount packaging qualified for high-temperature operation, and a typical current consumption of approximately 6 mA from the 3 V supply. The device provides improved accuracy at high temperatures compared to earlier MPXxx6115 series members. The SOIC-8 package is reflow-solder compatible and occupies roughly 13.4 mm × 7.5 mm of board area, enabling compact designs in cost-sensitive consumer products.
Technically, the MP3H6115A6T1 uses a piezo-resistive Wheatstone-bridge micromachined silicon diaphragm whose resistance changes proportionally to applied pressure; the on-chip op-amp buffers and temperature-corrects this bridge signal to deliver the calibrated ratiometric 0.12 V – 2.8 V output. The -40 °C to +125 °C operating range matches AEC-Q100-style thermal-stress profiles for under-hood automotive and industrial environments.
Typical applications include altimeters and variometers for handheld GPS units, barometric weather stations, HVAC pressure monitoring, medical respiratory equipment, and tire pressure monitoring reference implementations. The 15–115 kPa span covers the full meteorological range relevant to sea-level weather and consumer-grade altitude measurement.
When designing with this part, use a low-impedance buffer at the output if the ADC input draws more than a few microamperes, and ensure the supply rail is well-decoupled with a 100 nF ceramic capacitor. The -40 °C to +125 °C compensation range means external temperature correction does not apply for typical indoor and outdoor consumer deployments.

典型应用
MP3H6115A6T1 适用于 6 应用s: Handheld GPS Altimeter, Barometric Weather Station, HVAC Pressure Monitoring, Medical Respiratory Equipment, Industrial Vacuum and Process Control, Tire Pressure Monitoring Reference (TPMS).
Handheld GPS Altimeter
The MP3H6115A6T1 fits handheld GPS altimeters via its 15-115 kPa absolute pressure range that maps directly to barometric span from sea level (~101 kPa) to high altitudes (~15 kPa). Placed between the 3V battery rail and the GPS module's pressure-input ADC, the ratiometric 0.12 V-2.8 V output connects directly to a low-power MCU ADC channel for altitude conversion using h = 44330 × (1 - (P/P0)^(1/5.255)). Unlike uncompensated sensor elements, the on-chip -40 C to +125 C temperature compensation eliminates external calibration in portable outdoor deployments. The 8-SOIC surface-mount footprint and 13-inch tape-and-reel packaging enable high-volume SMT production for consumer GPS devices.
推荐
Barometric Weather Station
The MP3H6115A6T1 suits consumer and prosumer barometric weather stations because its 15-115 kPa absolute range spans the full meteorological window and its on-chip temperature compensation ensures stable readings across -40 C to +125 C outdoor swings. Connected to a 3V rail through a 100 nF decoupling capacitor, the ratiometric output feeds an MCU ADC for firmware-based barometric pressure and weather-trend computation. The male 0.13 inch (3.3 mm) tube port allows direct pneumatic attachment to a weather-station enclosure without external tubing adapters. XAIPART recommends verifying long-term stability against reference barometers during the 1000-hour reliability burn-in.
推荐
HVAC Pressure Monitoring
The MP3H6115A6T1 fits HVAC pressure monitoring applications where 15-115 kPa absolute readings correspond to duct and air-handler pressure conditions, and the ratiometric 0.12 V-2.8 V output integrates directly with industrial 3.3 V ADCs. The -40 C to +125 C compensated range covers the temperature extremes of mechanical-equipment closets and rooftop HVAC installations, eliminating the need for external thermal-correction firmware. The SOIC-8 surface-mount package and male tube port simplify assembly to a single reflow step plus a pneumatic fitting. Compared to bare MEMS die, the integrated amplifier and thin-film compensation reduce BOM cost and assembly time.
推荐
Medical Respiratory Equipment
The MP3H6115A6T1 fits medical respiratory equipment where 15-115 kPa absolute measurements align with airway and ventilator pressure monitoring, and the integrated on-chip signal conditioning provides clean analog signals to downstream medical-grade ADCs. The 0.12 V-2.8 V ratiometric output scales predictably with supply voltage, simplifying ADC reference design. The -40 C to +125 C compensated range covers the thermal environments of portable and emergency-care equipment. Designers must validate the part against their target medical safety standard (IEC 60601-1) during qualification; XAIPART notes the MP3H6115A6T1 is not explicitly medical-grade qualified per the manufacturer datasheet.
推荐
Industrial Vacuum and Process Control
The MP3H6115A6T1 is suitable for industrial vacuum and process-control applications where absolute pressure must be measured from atmospheric pressure down to partial-vacuum levels approaching 15 kPa, a range the 15-115 kPa transducer covers directly. The 0.12 V-2.8 V ratiometric output interfaces cleanly with industrial PLC analog-input modules powered from a 24 V bus stepped down to 3.0 V. The SOIC-8 package withstands standard reflow profiles for SMT production, while the male tube port mates directly to industrial pneumatic fittings. The on-chip -40 C to +125 C compensation ensures stable readings across factory-floor temperature swings.
推荐
Tire Pressure Monitoring Reference (TPMS)
The MP3H6115A6T1 fits tire pressure monitoring reference implementations where 15-115 kPa absolute sensing covers the full automotive tire-pressure range from low-tire warning (~150 kPa typical, measured as gauge-from-atmosphere 50 kPa above sea-level absolute) up to and beyond normal tire pressure. The 8-SOIC surface-mount package and -40 C to +125 C thermal range handle under-hood and wheel-well temperature extremes, while the on-chip conditioning simplifies the wireless-TPMS MCU interface. The male 0.13 inch (3.3 mm) tube port accepts standard tire-valve pneumatic interfaces. XAIPART notes this part is referenced as a reference design baseline; production TPMS deployments typically use custom AEC-Q100 qualified sensors.

设计说明
Place a 100 nF ceramic decoupling capacitor within a few millimeters of the Vdd pin (pin 1) to suppress switching noise from upstream regulators; the MP3H6115A6T1 ratiometric output is referenced to Vdd, so any noise on the supply rail couples directly into the pressure measurement. For battery-powered portable designs, a low-dropout regulator such as a 3.0 V LDO with <50 uVrms noise is recommended to preserve measurement accuracy.
Do not block the male 0.13 inch (3.3 mm) tube pressure port during PCB assembly; conformal coating, potting, or accidental solder paste ingress will seal the port and cause the sensor to read atmospheric pressure only. Do not exceed the recommended reflow profile (peak 260 C per JEDEC J-STD-020); the on-chip op-amp and thin-film resistor network are not qualified for multiple reflow cycles beyond the manufacturer-specified limit.
Route the analog Vout trace as a short, guarded trace away from switching converter inductors and digital clock lines to avoid coupling switching noise into the ratiometric pressure signal. Place the MP3H6115A6T1 away from heat sources such as power inductors and voltage regulators because thermal gradients across the SOIC package body appear as pressure-measurement offsets even with on-chip temperature compensation. Use a ground plane under the device for shielding.
