NXP Semiconductors MP3V5100GP

Overview

MP3V5100GP from Freescale Semiconductor is a fully signal-conditioned, temperature-compensated, and factory-calibrated silicon piezoresistive pressure sensor in a thermoplastic (PPS) surface-mount package. It delivers a ratiometric 0.1–3.1 V analog output over a 0–100 kPa (0–14.5 psi) gauge pressure range, with ±2.5% full-scale accuracy across 0°C to 85°C, and is designed for direct interface to microcontroller A/D inputs in medical and industrial sensing systems.

For engineers reviewing the MP3V5100GP datasheet, MP3V5100GP pinout, MP3V5100GP application, or MP3V5100GP equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios, and confirmed alternative options for pressure-sensing designs requiring stable analog output, low warm-up time (≤20 ms), and minimal offset drift (±0.5% VFSS after 1000-hour stress).

Technical Context

The MP3V5100GP integrates a patented silicon shear-stress strain gauge with on-chip bipolar signal conditioning, including two-stage gain amplification and ground-reference shift circuitry. Its ratiometric transfer function - Vout = VS × (0.009 × P + 0.06) - ensures output scaling directly proportional to supply voltage (2.7–3.3 Vdc), enabling robust performance without external reference components.

It operates as a gauge-pressure transducer with P1 (pressure side) and P2 (vacuum/reference side) ports physically isolated by fluorosilicone gel; pins 1, 5, 6, 7, and 8 are no-connects in the Case 1369-01 small-outline package. The device requires the decoupling network shown in Figure 3 (1.0 μF / 0.01 μF / 470 pF) to meet specified accuracy and response time (1.0 ms typical).

Key Specifications

FAQ

What is the pressure type supported by the MP3V5100GP?

The MP3V5100GP is a gauge-pressure sensor: it measures pressure relative to ambient atmospheric pressure using a dedicated reference port (P2). Its datasheet confirms single-port gauge configuration with P1 as the pressure side and P2 as the vacuum/reference side, sealed via fluorosilicone gel. This makes MP3V5100GP appropriate for applications like HVAC static pressure monitoring and respiratory airway sensing where atmospheric reference is inherent.

Does the MP3V5100GP require external calibration after soldering?

No, the MP3V5100GP does not require external calibration after soldering. It is factory-calibrated across temperature and pressure ranges, with on-chip temperature compensation and signal conditioning ensuring ±2.5% VFSS accuracy from 0°C to 85°C. The MP3V5100GP's offset and full-scale span are trimmed during manufacturing, and its ratiometric output eliminates dependency on external voltage references - enabling plug-and-play integration into MCU-based systems.

What is the maximum pressure the MP3V5100GP can withstand without damage?

The MP3V5100GP has a maximum pressure rating of 400 kPa (58 psi) for P1 > P2, as specified in Table 2 of its datasheet. Exceeding this value may cause permanent damage or degradation. While its operational range is 0–100 kPa, the device includes mechanical overpressure margin for transient spikes - critical in pump control and compressor monitoring where pressure surges occur. Always maintain P1 > P2 to preserve sensor integrity.

Can the MP3V5100GP operate from a 5 V supply?

No, the MP3V5100GP cannot operate from a 5 V supply. Its absolute maximum supply voltage is 3.3 Vdc, and recommended operation is strictly 2.7–3.3 Vdc per Table 1. Applying 5 V will exceed the maximum ratings and likely cause irreversible damage. For 5 V systems, an LDO or DC-DC converter must step down to 3.0 V before powering the MP3V5100GP - which also preserves its ratiometric accuracy and avoids violating the 10 mA max supply current limit.

Is the MP3V5100GP compatible with wet or corrosive media?

The MP3V5100GP is qualified for use with dry air as the pressure medium; Freescale explicitly states that other media may adversely affect performance and long-term reliability. Its fluorosilicone gel protects the die, but compatibility with liquids, oils, or aggressive gases is not guaranteed. For MP3V5100GP deployments involving non-dry-air media, consult NXP's application engineering team for media-specific validation - especially in medical fluid sensing or chemical processing applications.
