Product details
Overview
MPXH6300AC6T1 from Freescale Semiconductor is an absolute pressure sensor with 20–300 kPa range, integrated signal conditioning, on-chip temperature compensation (–40 °C to +125 °C), and ratiometric analog output (0.241–4.977 V at 5.1 V supply). It delivers ±1.5% full-scale span accuracy over 0–85 °C and is used in fuel-injected engine manifolds for precise air mass calculation.
For engineers reviewing the MPXH6300AC6T1 datasheet, MPXH6300AC6T1 pinout, MPXH6300AC6T1 application, or MPXH6300AC6T1 equivalent, key selection criteria include absolute pressure sensing capability, SSOP-8 thermoplastic package compatibility, calibrated analog voltage output, and LPG/CNG system suitability per OEM design requirements.
Technical Context
The MPXH6300AC6T1 implements a monolithic silicon piezoresistive sensing element with thin-film resistor networks and bipolar op amp circuitry for signal amplification and offset correction. Its transfer function is VOUT = VS × (0.00318 × P − 0.00353), where P is absolute pressure in kPa and VS is supply voltage.
On-chip temperature compensation corrects both offset and full-scale span across –40 °C to +125 °C using dedicated thin-film networks; error bands are bounded by ±4.0 kPa pressure error and ±1.5% VFSS accuracy over 0–85 °C, with response time ≤1.0 ms and warm-up time ≤20 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–304 kPa absolute; enables manifold pressure measurement in gasoline and LPG engines up to 3× atmospheric pressure. |
| Output Voltage Range | 0.241–4.977 V at VS = 5.1 V; provides 4.606 V full-scale span compatible with 12-bit ADCs without external gain. |
| Accuracy | ±1.5% of full-scale span over 0–85 °C; eliminates need for system-level calibration in automotive ECU designs. |
| Temperature Compensation | –40 °C to +125 °C; ensures stable offset and sensitivity in under-hood environments with thermal cycling. |
| Response Time | ≤1.0 ms (10–90%); supports real-time transient pressure tracking during rapid throttle transitions. |
| Supply Voltage | 4.74–5.46 VDC; ratiometric operation maintains output proportionality even with ±3% rail variation. |
| Sensitivity | 16.2 mV/kPa nominal; yields ~4.9 V output at 300 kPa, enabling high-resolution pressure digitization. |
Pinout & Package
MPXH6300AC6T1 uses Case 98ARH99089A: super small outline package (SSOP-8), surface-mount, thermoplastic body with ported top-side pressure inlet. Pin 1 identified by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect; internal device connection only - floating or grounded causes calibration drift. |
| 2 | VS | 5.1 V ±0.36 V supply input; ratiometric reference for output scaling and internal biasing. |
| 3 | GND | Analog ground return; must be low-impedance path shared with ADC reference ground. |
| 4 | VOUT | Analog voltage output (0.241–4.977 V); requires 100 nF decoupling and optional RC filter per Figure 4. |
| 5–8 | DNC | All unconnected; pins 5, 6, 7, 8 are internal die connections - no external routing permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Fully calibrated & compensated | Factory-trimmed offset, span, and temperature coefficients eliminate field calibration in production ECUs. |
| Fluorosilicone gel isolation | Protects wire bonds and die from moisture/chemical exposure while transmitting pressure to diaphragm - validated for LPG media. |
| Dual-port mounting options | Case 98ARH99089A supports tube attachment for remote sensing in confined engine bays or sealed enclosures. |
| High reliability micromachined silicon | Monolithic construction with stainless steel cap ensures >1 million pressure cycles and long-term stability (±0.25% VFSS offset shift). |
| Low power consumption | 6–10 mA supply current enables integration into always-on engine control modules without thermal derating. |
Applications
| Fuel-Injected Engine Manifold | Liquefied Petroleum Gas (LPG) Systems |

Use Value: 1 ms response time and –40 °C to +125 °C operation support cold-start performance and sustained high-load duty cycles. | Use Scenario: Monitoring compressed air or inert gas pressure in factory automation pneumatic circuits and HVAC ducts. IC Role / Device Role / Timing Role: Signal-conditioned analog pressure interface for PLC analog input modules requiring minimal external components. Use Value: Ratiometric 0.24–4.98 V output maps linearly to 20–300 kPa range, eliminating need for external voltage references or gain stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6T1 | 15–115 kPa range, same SSOP-8 package and pinout, ±1.5% VFSS accuracy, but lower max pressure rating. | Optimized for low-pressure turbocharged engines and HVAC static pressure sensing - insufficient for 300 kPa manifold peaks. | Select MPXH6115A6T1 only when pressure range ≤115 kPa is sufficient and cost reduction is prioritized. |
| MPX5700AP | 70–700 kPa range, SO-8 package, ±2.0% VFSS accuracy, no integrated temperature compensation beyond 0–85 °C. | Requires external compensation circuitry for operation above 85 °C; larger footprint limits PCB space-constrained engine control units. | Choose MPX5700AP only if extended high-pressure range is mandatory and thermal derating above 85 °C is acceptable. |
Compared with MPXH6115A6T1 and MPX5700AP, the MPXH6300AC6T1 uniquely balances 20–300 kPa coverage, factory-calibrated ±1.5% accuracy across 0–85 °C, and SSOP-8 form factor - making it optimal for mid-range automotive and industrial absolute pressure monitoring where size, precision, and media compatibility are jointly critical.

This range covers typical intake manifold pressures in naturally aspirated and moderately boosted gasoline and LPG engines, with full-scale output defined at 304 kPa and minimum rated pressure at 20 kPa.
Is the MPXH6300AC6T1 pin-compatible with other MPXH6300A variants?
Yes, the MPXH6300AC6T1 shares identical pinout and Case 98ARH99089A package with MPXH6300AC6U, as confirmed in the "Ordering Information" table and Figure 2 of the datasheet. Pins 1, 5–8 are DNC; VS (Pin 2), GND (Pin 3), and VOUT (Pin 4) retain identical functions and electrical specifications across all C6T1/C6U variants.
Does the MPXH6300AC6T1 require external temperature compensation?
No, the MPXH6300AC6T1 features fully integrated on-chip temperature compensation for both offset and full-scale span across –40 °C to +125 °C, as stated in the Features section and Section 3 of the datasheet. No external circuitry or software correction is needed to meet its ±1.5% VFSS accuracy specification over 0–85 °C.
What is the supply voltage requirement for stable operation of the MPXH6300AC6T1?
The MPXH6300AC6T1 operates with a supply voltage of 4.74–5.46 VDC at 25 °C, per Table 3. It is ratiometric: output voltage scales linearly with VS, so regulation within this window ensures compliance with its 0.241–4.977 V output range and ±1.5% VFSS accuracy - no additional voltage reference is required.
Can the MPXH6300AC6T1 be used with liquefied petroleum gas (LPG)?
Yes, the MPXH6300AC6T1 is explicitly validated for LPG applications per the "Typical applications" list and package porting description.
