Product details
Overview
MPXH6300AC6U from Freescale Semiconductor is a monolithic, signal-conditioned, absolute pressure sensor with 20–300 kPa range, ratiometric analog output (0.306 V to 4.912 V at 5.1 V supply), ±1.5% full-scale span accuracy over 0 °C to 85 °C, and on-chip temperature compensation from –40 °C to +125 °C. It is used in fuel-injected automotive engines and LPG/CNG vehicle systems for precise manifold or tank pressure monitoring.
For engineers reviewing the MPXH6300AC6U datasheet, MPXH6300AC6U pinout, MPXH6300AC6U application, or MPXH6300AC6U equivalent, key selection criteria include absolute pressure range, ratiometric output behavior, thermoplastic SSOP package compatibility, and integrated temperature compensation without external circuitry.
Technical Context
The MPXH6300AC6U integrates a piezoresistive silicon sensing element with bipolar op-amp gain stages, thin-film resistor networks for calibration, and on-die temperature compensation circuitry. Its transfer function is VOUT = VS × (0.00318 × P − 0.00353), with temperature-dependent error multipliers applied across –40 °C to +125 °C.
It operates as a ratiometric device: output voltage scales linearly with supply voltage (4.74–5.46 V), enabling direct interface with microcontroller ADCs without separate reference. The sealed vacuum reference cavity enables true absolute pressure measurement, and fluorosilicone gel encapsulation protects wire bonds while transmitting pressure to the diaphragm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–304 kPa absolute; supports engine manifold and LPG tank monitoring without overpressure risk up to 1200 kPa max rating. |
| Output Voltage | 0.306 V (min offset) to 4.912 V (typical full-scale) at 5.1 V supply; ratiometric scaling simplifies ADC reference design. |
| Accuracy | ±1.5% of full-scale span over 0–85 °C; includes linearity, temp hysteresis, pressure hysteresis, and TcSpan/TcOffset errors. |
| Supply Voltage | 4.74–5.46 V DC; operation within this range ensures specified output linearity and temperature compensation integrity. |
| Response Time | 1.0 ms (10–90%); suitable for dynamic combustion cycle pressure tracking in internal combustion engines. |
| Operating Temp | –40 °C to +125 °C; fully compensated output enables under-hood automotive deployment without external thermal management. |
| Sensitivity | 16.2 mV/kPa; provides high-resolution analog output for 12-bit ADCs with >1 kPa effective resolution. |
Pinout & Package
MPXH6300AC6U uses Case 98ARH99089A - a surface-mount super small outline package (SSOP) with 8 leads, chamfered corner marking Pin 1. Pins 1, 5, 6, 7, and 8 are internal connections and must remain unconnected. Only three pins are functional: VS (supply), GND (ground), and VOUT (ratiometric analog output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 (VS) | Voltage supply input | Accepts 4.74–5.46 V DC; powers internal op-amps and sensing element; output scales ratiometrically with this rail. |
| Pin 3 (GND) | Analog ground reference | Common return for supply and output; must be low-impedance path to avoid offset drift or noise coupling. |
| Pin 4 (VOUT) | Analog output signal | 0.306–4.912 V DC output proportional to absolute pressure; directly interfaces with MCU ADC inputs. |
| Pins 1,5–8 (DNC) | Do-not-connect terminals | Internal die connections only; floating or grounded connections will degrade performance or cause failure. |
Key Features
| Feature | Design Value |
|---|---|
| Fully calibrated & compensated | Factory-trimmed thin-film resistors deliver ±1.5% accuracy over 0–85 °C without external calibration circuitry. |
| On-chip temperature compensation | Integrated circuitry corrects offset and span drift across –40 °C to +125 °C, eliminating need for software lookup tables. |
| Ratiometric output | VOUT scales linearly with VS, enabling use of same supply for sensor and ADC-removing reference voltage error sources. |
| Dual-port mounting options | Package porting supports tube attachment for remote sensing in LPG/CNG tanks or engine manifolds with physical separation. |
| Fluorosilicone gel isolation | Protects bond wires and die surface from moisture/chemical exposure while maintaining pressure transmission fidelity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A | 15–115 kPa range, same SSOP package (98ARH99066A), ±1.5% accuracy, but lower pressure ceiling. | Optimized for low-pressure applications like HVAC or medical devices-not suitable for LPG/CNG tank monitoring. | Select MPXH6115A only when system pressure remains below 115 kPa and cost sensitivity outweighs range flexibility. |
| MPX5700AP | 70–700 kPa range, different SO-8 package (98ARH99071A), ±2.0% accuracy, no factory calibration trim. | Requires external compensation circuitry; better suited for high-pressure industrial hydraulics than automotive fuel systems. | Choose MPX5700AP only if pressure range exceeds 304 kPa and board layout accommodates larger SO-8 footprint. |
Compared with MPXH6115A and MPX5700AP, the MPXH6300AC6U uniquely balances 20–304 kPa range, ±1.5% accuracy, factory calibration, and SSOP packaging-making it optimal for automotive LPG/CNG and engine MAP where mid-range precision and compact size are critical.

FAQ
What is the absolute pressure range supported by the MPXH6300AC6U?
The MPXH6300AC6U supports an absolute pressure range of 20 kPa to 304 kPa, with a maximum rated pressure of 1200 kPa. Its sealed vacuum reference enables accurate measurement relative to absolute zero pressure, making it suitable for engine manifold and LPG tank applications where ambient barometric variation must not affect readings. The MPXH6300AC6U maintains specified accuracy across its full 20–304 kPa operating band.
Does the MPXH6300AC6U require external calibration or compensation components?
No, the MPXH6300AC6U does not require external calibration or compensation components. It integrates on-chip thin-film resistor networks, bipolar op-amp circuitry, and temperature compensation logic that deliver ±1.5% full-scale span accuracy over 0 °C to 85 °C. The MPXH6300AC6U is fully calibrated at the factory and operates as a self-contained analog pressure transducer with only VS, GND, and VOUT connections needed.
What package type and pin configuration does the MPXH6300AC6U use?
The MPXH6300AC6U uses Case 98ARH99089A - a surface-mount super small outline package (SSOP) with 8 leads and a chamfered corner marking Pin 1. Only three pins are functional: Pin 2 (VS), Pin 3 (GND), and Pin 4 (VOUT). Pins 1 and 5–8 are do-not-connect (DNC) internal terminals and must remain unconnected in the PCB layout to ensure proper operation of the MPXH6300AC6U.
How does the ratiometric output of the MPXH6300AC6U benefit system design?
The MPXH6300AC6U features a ratiometric output where VOUT scales linearly with supply voltage (VS), enabling direct connection to an MCU's ADC using the same 5 V supply for both sensor and reference. This eliminates errors caused by independent voltage references and simplifies power architecture. For example, if VS drifts ±3%, VOUT drifts identically-preserving measurement ratio integrity. This behavior is intrinsic to the MPXH6300AC6U's internal gain-stage design and requires no firmware compensation.
Is the MPXH6300AC6U compatible with liquefied petroleum gas (LPG) or compressed natural gas (CNG) environments?
Yes, the MPXH6300AC6U is explicitly designed for LPG and CNG vehicle applications. Its thermoplastic SSOP package and fluorosilicone gel encapsulation provide chemical resistance and environmental isolation, while package porting allows tube-based remote mounting to separate the sensor electronics from direct fuel exposure. The MPXH6300AC6U datasheet cites "vehicles powered by green gases (for example LPG and CNG)" as a typical application, confirming its suitability when installed per recommended mechanical interface guidelines.
