Product details
Overview
MPXH6300A6T1 from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with monolithic silicon piezoresistive sensing element, on-chip bipolar op-amp signal conditioning, and thin-film temperature compensation. It delivers 4.912 V typical full-scale output at 5.1 V supply across 20–304 kPa range, ±1.5% accuracy over 0 °C to 85 °C, and operates from −40 °C to +125 °C - used in LPG/CNG fuel systems for precise manifold pressure feedback.
For engineers reviewing the MPXH6300A6T1 datasheet, MPXH6300A6T1 pinout, MPXH6300A6T1 application, or MPXH6300A6T1 equivalent, key selection criteria include absolute pressure range (20–304 kPa), ratiometric 5.1 V ±0.36 V excitation, 1.0 ms response time, 16.2 mV/kPa sensitivity, and SSOP-8 package compatibility with surface-mount reflow assembly.
Technical Context
The MPXH6300A6T1 integrates a micromachined silicon diaphragm with piezoresistive elements, thin-film resistor networks for gain/offset trimming, and two-stage bipolar op-amp circuitry. Its sealed vacuum reference enables true absolute pressure measurement, and fluorosilicone gel encapsulation protects wire bonds while transmitting pressure to the die.
On-chip temperature compensation corrects offset and span drift across −40 °C to +125 °C using analog circuitry - not digital calibration - with a linear temperature multiplier (1× from 0–85 °C, 3× at −40 °C and 125 °C). The transfer function is VOUT = VS × (0.00318 × P − 0.00353), where P is pressure in kPa and VS is supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–304 kPa absolute - supports engine manifold pressure monitoring up to ~3 bar gauge-equivalent in LPG/CNG applications. |
| Supply Voltage | 4.74–5.46 VDC - ratiometric operation ensures output scaling tracks supply variation, simplifying ADC reference design. |
| Full-Scale Output | 4.847–4.977 VDC at 5.1 V supply - high-level analog output eliminates need for external amplification before 12-bit+ ADC. |
| Accuracy | ±1.5% of full-scale span over 0–85 °C - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset errors. |
| Response Time | 1.0 ms (10% to 90%) - enables real-time closed-loop fuel control in internal combustion engines with <100 Hz dynamics. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive environments without external thermal shielding. |
| Sensitivity | 16.2 mV/kPa - provides >4.9 V swing over full range, improving SNR and reducing quantization error in 5 V ADC systems. |
Pinout & Package
MPXH6300A6T1 uses the super small outline package (SSOP-8), case number 98ARH99066A, with 1.27 mm pitch, surface-mount footprint, and chamfered corner marking Pin 1. The package is thermoplastic, hermetically sealed with stainless steel cap and fluorosilicone gel isolation for media compatibility with dry air and LPG.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect - internal device connection; chamfered corner identifies this pin for orientation. |
| Pin 2 | VS | Voltage supply input - accepts 4.74–5.46 VDC; requires local 1 μF decoupling per datasheet Figure 4. |
| Pin 3 | GND | Analog ground reference - must be low-impedance return path shared with ADC ground to minimize offset error. |
| Pin 4 | VOUT | Analog output voltage - ratiometric, 0.306 V min to 4.912 V typ over pressure range; drives 10 kΩ+ loads. |
| Pins 5–8 | DNC | Do not connect - internal connections only; floating or grounded pins cause calibration drift or damage. |
Key Features
| Feature | Design Value |
|---|---|
| Fully calibrated & compensated | Factory-trimmed offset, span, and temperature coefficients - no system-level calibration required for ±1.5% accuracy. |
| Temperature-compensated | Analog compensation from −40 °C to +125 °C - maintains accuracy without microcontroller-based correction algorithms. |
| High-output analog signal | 4.912 V typical full-scale output - directly interfaces with 5 V ADCs without gain stages or level-shifting. |
| Media-compatible packaging | Fluorosilicone gel + stainless steel cap - validated for dry air and compatible with liquefied petroleum gas (LPG) in remote-sensing configurations. |
| SSOP-8 surface-mount form factor | Compact 3.81 mm × 4.83 mm footprint - enables high-density placement in engine control units and portable gas analyzers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV7025GP | 25 kPa full-scale range, 0.5–4.5 V ratiometric output, SO-8 package; lower pressure range and different transfer function slope. | Designed for low-pressure medical devices and HVAC differential sensing - not suitable for 300 kPa engine manifolds. | Select MPXV7025GP only if measuring sub-atmospheric or low-gauge pressures; MPXH6300A6T1 remains optimal for 20–304 kPa absolute. |
| SPX3010AT | 300 kPa absolute range, 0.5–4.5 V output, SO-8, integrated digital I²C interface; requires MCU firmware support and external power regulation. | Targets smart sensors with digital output and self-diagnostics - adds complexity but enables multi-drop bus architecture. | Choose SPX3010AT when digital communication, built-in diagnostics, or multi-sensor synchronization are required; MPXH6300A6T1 excels in cost-sensitive analog-only systems. |
Compared with MPXV7025GP and SPX3010AT, the MPXH6300A6T1 offers the only combination of 300 kPa absolute range, high-level analog output (>4.8 V), and factory-calibrated ±1.5% accuracy in a thermoplastic SSOP-8 package - making it uniquely suited for automotive LPG/CNG and industrial MAP applications without digital overhead.

FAQ
What is the pressure range and reference type of the MPXH6300A6T1?
The MPXH6300A6T1 is an absolute pressure sensor with a specified range of 20–304 kPa. It uses a sealed vacuum reference cavity, meaning its output reflects pressure relative to absolute zero (vacuum), not ambient atmospheric pressure. This makes it suitable for applications like engine manifold pressure sensing where true absolute pressure is required for accurate air mass calculation. The MPXH6300A6T1 does not support gauge or differential modes.
Does the MPXH6300A6T1 require external calibration or trimming?
No, the MPXH6300A6T1 is fully calibrated and temperature-compensated at the factory. Its on-chip thin-film resistor networks and bipolar op-amp circuitry provide trimmed offset, full-scale span, and temperature coefficients across −40 °C to +125 °C. System-level calibration is not required to achieve the specified ±1.5% accuracy over 0–85 °C. The MPXH6300A6T1 delivers plug-and-play analog output performance without microcontroller-based compensation routines.
What are the supply voltage requirements and current draw for the MPXH6300A6T1?
The MPXH6300A6T1 operates from 4.74 V to 5.46 V DC, with a typical supply current of 6.0 mA and maximum of 10 mA at 25 °C. It is ratiometric: output voltage scales linearly with supply voltage, so using the same supply for both the MPXH6300A6T1 and the ADC reference improves measurement stability. A 1 μF ceramic capacitor is required between VS and GND, placed as close as possible to the device pins, per the recommended layout in the MPXH6300A6T1 datasheet.
Can the MPXH6300A6T1 be used with LPG or other fuel gases?
Yes - the MPXH6300A6T1 is validated for use with liquefied petroleum gas (LPG) in remote-sensing configurations. Its fluorosilicone gel encapsulation and stainless steel cap provide chemical compatibility and mechanical protection against fuel vapors. However, the datasheet specifies that qualification testing used dry air as the pressure medium; for non-air media, consult NXP's application engineering team to confirm long-term reliability in your specific LPG composition, pressure cycling profile, and temperature conditions. The MPXH6300A6T1 itself is not rated for direct immersion in liquid fuel.
What is the pin configuration and which pins must remain unconnected on the MPXH6300A6T1?
The MPXH6300A6T1 uses an 8-pin SSOP package (case 98ARH99066A) with Pin 1 identified by a chamfered corner. Only Pins 2 (VS), 3 (GND), and 4 (VOUT) are functional. Pins 1 and 5–8 are marked DNC (Do Not Connect) - they are internal device connections and must remain floating (not tied to GND, VS, or any other node), as connecting them may cause calibration drift, output instability, or permanent damage. The MPXH6300A6T1 has no user-accessible trim or configuration pins.
