Product details
Overview
MPXH6101A6U from Freescale Semiconductor is a monolithic, signal-conditioned, absolute pressure sensor with 15–102 kPa range, ±1.72% full-scale error over 0 °C to 85 °C, and ratiometric 5 V supply operation. It delivers a high-level analog output (0.168–4.933 V) proportional to absolute intake manifold pressure and is used in engine control systems for fuel metering calculations.
For engineers reviewing the MPXH6101A6U datasheet, MPXH6101A6U pinout, MPXH6101A6U application, or MPXH6101A6U equivalent, key selection considerations include its thermoplastic (PPS) SSOP-8 package, on-chip temperature compensation across –40 °C to +125 °C, 15 ms response time, and compatibility with microcontroller ADC interfaces via recommended decoupling.
Technical Context
The MPXH6101A6U integrates a piezoresistive silicon sensing element with thin-film metallization and bipolar signal conditioning circuitry-including two gain stages, temperature compensation, and ground reference shift-within a single die. Its transfer function is VOUT = VS × (0.01059 × P − 0.10941), calibrated for dry air media.
It operates as a ratiometric device: output voltage scales linearly with supply voltage (4.75–5.25 V), enabling direct interface with 5 V microcontrollers without external scaling. The sealed vacuum reference and fluorosilicone gel isolation ensure stable absolute pressure measurement under automotive thermal and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–102 kPa absolute; covers typical automotive manifold vacuum-to-boost conditions including idle (≈20 kPa) and wide-open throttle (≈100 kPa). |
| Supply Voltage | 4.75–5.25 Vdc; ratiometric operation ensures output tracking with MCU VDD, eliminating need for separate precision reference. |
| Output Voltage Range | 0.168–4.933 Vdc at 25 °C; spans >4.7 V full-scale span, enabling 12-bit+ resolution with standard 5 V ADCs. |
| Accuracy | ±1.72 %VFSS over 0–85 °C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 15 ms (10–90%); sufficient for real-time cylinder-by-cylinder fuel calculation in engines up to ~8000 RPM. |
| Operating Temperature | −40 to +125 °C ambient; supports under-hood placement with on-chip compensation active across full range. |
| Package | 8-lead SSOP (case 98ARH99066A); surface-mount thermoplastic (PPS) housing with stainless steel pressure port cap. |
Pinout & Package
MPXH6101A6U uses an 8-lead Super Small Outline Package (SSOP), case 98ARH99066A, with thermoplastic (PPS) body and stainless steel pressure port cap. Pin 1 is identified by a chamfered corner. Pins 1, 5–8 are internal connections and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect; internal device connection; chamfered corner identifies this pin. |
| 2 | VS | Voltage supply input (4.75–5.25 Vdc); requires 100 nF decoupling capacitor per datasheet Figure 4. |
| 3 | GND | Analog ground reference; must be connected to system AGND with low-impedance path. |
| 4 | VOUT | Analog output (0.168–4.933 Vdc); connects directly to MCU ADC input with optional RC filter (51 kΩ + 47 pF). |
| 5–8 | DNC | All unconnected; internal die connections only-no external routing permitted. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over −40 °C to +125 °C operating range; eliminates need for external calibration circuitry in engine control units. |
| Ratiometric output | Output scales linearly with VS; enables direct use with 5 V microcontrollers without reference voltage matching or gain adjustment. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture, oil, and combustion byproducts while transmitting pressure accurately to diaphragm. |
| Sealed vacuum reference | Enables true absolute pressure measurement referenced to perfect vacuum-critical for barometric correction in altitude-varying engine control. |
| Stainless steel pressure port | Provides robust, corrosion-resistant interface to intake manifold; compatible with standard automotive hose barbs and gasket sealing. |
Applications
| Engine Control Unit (ECU) | Automotive Diagnostic Tool |

Use Value: Maintains ±1.72% accuracy despite ambient temperature swings, eliminating drift-related maintenance cycles. |
Use Scenario: Pressure feedback in portable ventilators and anesthesia machines requiring precise sub-atmospheric and near-atmospheric pressure sensing. IC Role / Device Role / Timing Role: Ratiometric analog output referenced to sealed vacuum, enabling accurate tidal volume calculation from differential pressure drop across flow sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7002DP | Differential output (0–5 V), dual-port, 2–100 kPa range; lacks on-chip temperature compensation above 85 °C. | Requires external compensation for under-hood ECU use; suited for clean-air differential flow sensing, not absolute MAP. | Select MPXV7002DP only when differential pressure measurement and lower cost outweigh need for absolute reference and extended temp compensation. |
| SPX3010-015 | 15–115 kPa range, ±1.5% accuracy, 3.3 V supply; uses ceramic package and different pinout (SOT-23-6). | Not pin-compatible; requires PCB redesign; optimized for low-power battery-operated devices rather than 5 V automotive systems. | Choose SPX3010-015 if 3.3 V rail availability, smaller footprint, and tighter accuracy tolerance justify layout change and recalibration. |
Compared with MPXH6101A6U, MPXV7002DP offers differential capability but sacrifices absolute reference and high-temp compensation, while SPX3010-015 provides improved accuracy and lower voltage operation at the cost of pin compatibility and automotive qualification depth.

FAQ
What is the pressure media compatibility of the MPXH6101A6U?
The MPXH6101A6U is qualified for use with dry air as the pressure medium. Its fluorosilicone gel isolation protects the die from moisture and mild contaminants, but exposure to oils, fuels, or corrosive gases may degrade long-term performance. Freescale explicitly states that media other than dry air may adversely affect reliability-consult factory documentation before deploying MPXH6101A6U in non-dry-air environments.
Does the MPXH6101A6U require external calibration for automotive use?
No, the MPXH6101A6U includes factory-calibrated, on-chip temperature compensation covering −40 °C to +125 °C and a ratiometric output architecture. This eliminates need for external trim components or system-level calibration routines in production ECUs-MPXH6101A6U delivers specified ±1.72% accuracy out-of-box across its operating temperature and pressure range.
What is the recommended power supply decoupling for the MPXH6101A6U?
Freescale specifies a 100 nF ceramic capacitor between VS and GND, placed as close as possible to pins 2 and 3. For optimal noise immunity in noisy automotive environments, MPXH6101A6U should also be paired with the recommended RC filter (51 kΩ series resistor + 47 pF capacitor to GND) on VOUT before connecting to an ADC input.
Can the MPXH6101A6U be used in non-automotive applications?
Yes-the MPXH6101A6U is widely deployed in industrial vacuum monitoring, HVAC refrigerant recovery, and portable medical devices. Its absolute pressure reference, wide temperature range, and stainless steel port make it suitable wherever stable, calibrated 15–102 kPa measurement is required-even outside automotive contexts-as confirmed in the official datasheet Applications section.
What does "DNC" mean for pins 1 and 5–8 on the MPXH6101A6U?
"DNC" stands for "Do Not Connect." Pins 1, 5, 6, 7, and 8 are internal device connections with no external functionality. They must remain unconnected to any trace, pad, or ground plane. Connecting them risks damaging the MPXH6101A6U or degrading accuracy-this requirement is explicitly stated in Table 1 of the MPXH6101A datasheet Rev. 7.1.
