Product details
Overview
MPXH6101A6T1 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 intake manifold pressure for fuel calculation in engine control systems.
For engineers reviewing the MPXH6101A6T1 datasheet, MPXH6101A6T1 pinout, MPXH6101A6T1 application, or MPXH6101A6T1 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 MPXH6101A6T1 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-enabling direct analog voltage output without external amplification. Its sealed vacuum reference and fluorosilicone gel isolation ensure stable absolute pressure measurement using dry air as the media.
It operates ratiometrically with a 4.75–5.25 V supply, draws ≤10 mA, and exhibits ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling. The transfer function VOUT = VS × (0.01059×P − 0.10941) is calibrated over 0–85 °C, with output saturation outside 15–102 kPa.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–102 kPa absolute; covers typical automotive intake manifold vacuum-to-boost conditions. |
| Accuracy | ±1.72% VFSS over 0–85 °C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, TcOffset, and nominal variation. |
| Supply Voltage | 4.75–5.25 Vdc; ratiometric operation ensures output scaling with supply, simplifying ADC reference design. |
| Output Voltage | 0.168–4.933 Vdc at min/max pressure (25 °C); provides >4.4 V full-scale span for high SNR ADC digitization. |
| Response Time | 15 ms (10%–90%); enables real-time cylinder-by-cylinder fuel mapping in gasoline engines up to ~8000 RPM. |
| Operating Temp | −40 to +125 °C ambient; supports under-hood deployment with on-chip compensation active from −40 to +125 °C. |
| Sensitivity | 52.95 mV/kPa; linear analog output slope allows direct pressure computation without lookup tables. |
Pinout & Package
MPXH6101A6T1 uses an 8-lead Super Small Outline Package (SSOP), case 98ARH99066A, with thermoplastic (PPS) body and stainless steel cap identifying the pressure (P1) side. Pins 1, 5–8 are internal DNC terminals; only pins 2 (VS), 3 (GND), and 4 (VOUT) are externally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect; chamfered corner identifies pin 1; internal connection only. |
| Pin 2 | VS | Voltage supply input (4.75–5.25 Vdc); requires 100 nF decoupling per datasheet Figure 4. |
| Pin 3 | GND | Analog ground reference; must be low-impedance return path shared with microcontroller ADC ground. |
| Pin 4 | VOUT | Analog output (0.168–4.933 V); connects directly to ADC input with optional 47 pF filter per Figure 4. |
| Pins 5–8 | DNC | Do not connect; internal device connections with no external functionality. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated over −40 to +125 °C operating range; eliminates need for external calibration circuitry in engine bay environments. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture and contaminants while transmitting pressure; qualified for dry air media only. |
| Ratiometric output | Output scales linearly with supply voltage; enables use of same 5 V rail for sensor and ADC reference, reducing BOM count. |
| Monolithic silicon construction | Integrates sensing element, signal conditioning, and compensation on single die; improves long-term stability vs hybrid assemblies. |
| SSOP-8 surface-mount package | 0.387″ × 0.150″ footprint (9.83 mm × 3.81 mm); compatible with standard reflow processes and automated assembly. |

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 | Wider 15–115 kPa range; identical SSOP-8 package, pinout, and signal conditioning architecture. | Better suited for turbocharged engines requiring higher boost pressure headroom. | Select MPXH6115A6T1 if system max pressure exceeds 102 kPa; otherwise MPXH6101A6T1 offers tighter error budget at lower cost. |
| MPX5700AP | 70 kPa absolute range; SO-8 package with different pinout (VS/VOUT/GND on pins 1/2/3); no PPS thermoplastic body. | Designed for industrial pressure monitoring rather than automotive MAP; lacks extended temp compensation beyond 85 °C. | Use MPX5700AP only if footprint and temperature range requirements align; MPXH6101A6T1 provides superior under-hood reliability. |
Compared with MPXH6115A6T1 and MPX5700AP, the MPXH6101A6T1 delivers optimal balance of automotive-grade temperature robustness (−40 to +125 °C), tight 15–102 kPa range coverage, and SSOP-8 manufacturability-making it the preferred choice for cost-sensitive, high-volume engine control modules.

FAQ
What is the pressure media compatibility of the MPXH6101A6T1?
The MPXH6101A6T1 is qualified for use with dry air as the pressure media only. Its fluorosilicone gel isolation protects the die but does not guarantee compatibility with fuels, oils, or corrosive gases. Using non-dry-air media may degrade long-term performance or cause irreversible damage. For alternative media, consult NXP's factory application engineering team before deployment.
Does the MPXH6101A6T1 require external signal conditioning?
No, the MPXH6101A6T1 integrates full signal conditioning-including temperature compensation, gain stages, and offset correction-delivering a ratiometric analog voltage output directly usable by a microcontroller ADC. Only a 100 nF supply decoupling capacitor and optional 47 pF output filter (per Figure 4 of the datasheet) are required for stable operation.
What is the meaning of "DNC" on pins 1 and 5–8 of the MPXH6101A6T1?
"DNC" stands for "Do Not Connect." Pins 1, 5, 6, 7, and 8 are internal device connections with no external electrical function. Pin 1 is marked by a chamfered corner for orientation; connecting any DNC pin to ground, supply, or signal traces violates the device specification and may impair accuracy or cause failure.
How does the MPXH6101A6T1 handle temperature variations across its full operating range?
The MPXH6101A6T1 features on-chip temperature compensation active from −40 °C to +125 °C, ensuring specified accuracy (±1.72% VFSS) over 0–85 °C and functional operation across the full range. Offset stability remains within ±0.5%VFSS after 1000-hour thermal cycling, making it suitable for under-hood automotive placement without external thermal management.
Is the MPXH6101A6T1 pin-compatible with other Freescale MAP sensors like the MPXH6115A6T1?
Yes, the MPXH6101A6T1 and MPXH6115A6T1 share identical SSOP-8 package (case 98ARH99066A), pinout, and terminal functions-making them drop-in replacements where pressure range requirements allow. Both use pins 2 (VS), 3 (GND), and 4 (VOUT) identically; no PCB layout changes are needed for substitution within their respective pressure limits.
