Product details
Overview
MPXH6300A6U from Freescale Semiconductor is an absolute pressure sensor with 20–304 kPa range, ratiometric 0.306–4.912 V output at 5.1 V supply, ±1.5% full-scale accuracy over 0–85 °C, and integrated on-chip temperature compensation. It serves as a primary analog pressure transducer in fuel-injected engine control units and LPG/CNG vehicle systems.
For engineers reviewing the MPXH6300A6U datasheet, MPXH6300A6U pinout, MPXH6300A6U application, or MPXH6300A6U equivalent, this page delivers verified electrical specs, validated SSOP-8 pin mapping, real-world automotive and industrial use cases, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The MPXH6300A6U integrates a micromachined silicon piezoresistive sensing element with bipolar op-amp signal conditioning and thin-film resistor networks for high-level analog output. Its sealed vacuum reference enables true absolute pressure measurement across the full 20–304 kPa range.
On-chip temperature compensation operates from –40 °C to +125 °C, with error bands bounded by ±4.0 kPa pressure error and ±1.5% VFSS accuracy over 0–85 °C. The device is ratiometric to supply voltage (4.74–5.46 V), delivering 16.2 mV/kPa sensitivity and 1.0 ms response time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–304 kPa absolute: supports low-pressure natural gas and intake manifold monitoring without external amplification. |
| Output Voltage | 0.306–4.912 V at VS = 5.1 V: directly interfaces 12-bit ADCs with ≥4.6 V span for >12-bit effective resolution. |
| Accuracy | ±1.5% of full-scale span (VFSS) over 0–85 °C: eliminates need for system-level calibration in automotive ECU designs. |
| Supply Voltage | 4.74–5.46 V DC: compatible with standard 5 V rail regulators; ratiometric behavior maintains linearity across supply variation. |
| Response Time | 1.0 ms (10–90%): captures transient pressure events in internal combustion engine cycles up to 500 Hz. |
| Operating Temp | –40 to +125 °C: qualified for under-hood automotive placement with no derating required. |
| Package | Case 98ARH99066A, SSOP-8: surface-mount thermoplastic package with ported top-side pressure inlet for LPG tube attachment. |
Pinout & Package
MPXH6300A6U uses Freescale's super small outline package (SSOP-8), case number 98ARH99066A, with a top-side pressure port and chamfered corner marking Pin 1. Pins 1, 5–8 are internally connected and must remain unconnected in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect - internal connection; chamfered corner identifies orientation. |
| Pin 2 | VS | Voltage supply input (4.74–5.46 V); requires 1 μF decoupling capacitor per datasheet Figure 4. |
| Pin 3 | GND | Analog ground reference; must be tied to clean system ground plane with minimal impedance. |
| Pin 4 | VOUT | Ratiometric analog output (0.306–4.912 V); connects directly to ADC input with optional 47 pF filter. |
| Pins 5–8 | DNC | All unconnected - internal die connections; floating or grounded traces cause measurement drift. |
Key Features
| Feature | Design Value |
|---|---|
| Fully calibrated & compensated | Factory-trimmed offset, span, and temperature coefficients eliminate post-mount calibration effort in production. |
| Fluorosilicone gel isolation | Protects wire bonds and die from moisture and chemical exposure while transmitting pressure to diaphragm - validated for LPG media. |
| Sealed vacuum reference | Enables true absolute pressure measurement critical for barometric correction in engine air mass calculation. |
| Thermoplastic SSOP-8 package | Enables automated SMT assembly and withstands reflow profiles up to 260 °C peak; porting allows flexible hose/tube mounting. |
| 1.0 ms response time | Supports closed-loop fuel injection timing where pressure transients occur within single engine cycle (e.g., 6000 RPM = 100 Hz). |
Applications
| Fuel-Injected Engine Control | Liquefied Petroleum Gas (LPG) Vehicle Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6U | 15–115 kPa range, 0.2–4.8 V output, ±2.0% VFSS accuracy over 0–85 °C; same SSOP-8 package and pinout. | Lower pressure ceiling limits use in turbocharged engines or high-altitude barometric sensing. | Select when system max pressure stays below 115 kPa and cost sensitivity outweighs extended range needs. |
| MPX5700AP | 15–700 kPa range, 0.2–4.8 V output, ±2.5% VFSS accuracy, 8-pin DIP package with dual ports. | Dual-port differential capability and wider range suit HVAC refrigerant monitoring but require different PCB footprint. | Choose for higher-pressure industrial applications where SSOP-8 mounting is not required and differential sensing adds value. |
Compared with MPXH6300A6U, MPXH6115A6U offers identical form factor and integration but trades 304 kPa upper limit for lower cost, while MPX5700AP sacrifices SSOP-8 surface-mount compatibility for broader pressure coverage and differential mode - neither is pin-compatible, but both serve adjacent design requirements.

FAQ
What is the absolute pressure range supported by the MPXH6300A6U?
The MPXH6300A6U supports an absolute pressure range of 20 to 304 kPa, with full-scale output defined at 304 kPa. This range covers atmospheric pressure (≈101 kPa) through boosted intake manifolds and low-pressure LPG vapor lines. The device uses a sealed vacuum reference cavity, ensuring accurate absolute measurements independent of ambient barometric variation - a key requirement for MPXH6300A6U deployment in engine control and alternative fuel systems.
Does the MPXH6300A6U require external calibration after soldering?
No, the MPXH6300A6U is fully calibrated and temperature-compensated at the factory. Its on-chip thin-film resistor networks and bipolar op-amp circuitry provide stable offset, span, and thermal coefficients across –40 to +125 °C. Users do not need system-level calibration for MPXH6300A6U in standard applications; only basic power supply decoupling (1 μF) and optional output filtering (47 pF) are required per the datasheet.
What is the correct PCB footprint for the MPXH6300A6U package?
The MPXH6300A6U uses Case 98ARH99066A - a super small outline package (SSOP-8) with 0.050 inch (1.27 mm) lead pitch. The recommended footprint matches Freescale's Figure 9: 0.150 inch (3.81 mm) body width, 0.387 inch (9.83 mm) length, and 0.027 inch (0.69 mm) pad width. Pins 1, 5–8 must remain unconnected; only Pins 2 (VS), 3 (GND), and 4 (VOUT) are active in the MPXH6300A6U layout.
Can the MPXH6300A6U be used with media other than dry air?
The MPXH6300A6U is qualified for dry air per Freescale's reliability testing, but its fluorosilicone gel isolation and stainless steel cap enable proven compatibility with liquefied petroleum gas (LPG). For other media - including CNG, solvents, or corrosive gases - contact NXP (ex-Freescale) for media compatibility validation. Unqualified media may degrade MPXH6300A6U long-term performance or cause irreversible sensor drift.
What is the supply current consumption of the MPXH6300A6U at nominal conditions?
The MPXH6300A6U draws 6.0 mA typical and up to 10 mA maximum supply current at VS = 5.1 V and TA = 25 °C. This quiescent current remains stable across the operating temperature range and supports continuous operation in battery-backed automotive modules. The low 6 mA typical draw makes MPXH6300A6U suitable for always-on engine control subsystems without excessive thermal loading.
