NXP Semiconductors MP3V5100GC6U

Overview

MP3V5100GC6U from Freescale Semiconductor is a gauge-pressure sensor IC with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.1–3.1 V analog output over 0–100 kPa (0–14.5 psi), operates from 2.7–3.3 V supply, draws ≤10 mA, and achieves ±2.5% full-scale accuracy across –40°C to +125°C. It is used in patient monitoring and pump/motor control systems requiring stable, low-power pressure sensing.

For engineers reviewing the MP3V5100GC6U datasheet, MP3V5100GC6U pinout, MP3V5100GC6U application, or MP3V5100GC6U equivalent, this page provides verified package mapping (Case 482A-01), confirmed gauge configuration, validated transfer function (V_OUT = V_S × (0.009 × P + 0.06)), and real-world application constraints including dry-air media requirement and decoupling circuit necessity.

Technical Context

The MP3V5100GC6U integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing on a monolithic die. Its on-chip circuitry includes two gain stages, temperature compensation, offset calibration, and ground reference shift - all optimized for microcontroller A/D interfacing.

It is strictly a gauge-pressure device (P1 referenced to ambient) with no differential or absolute variants supported in this exact part number. Pins 1, 5, 6, 7, and 8 are NC; only pins 2 (V_OUT), 3 (GND), and 4 (V_S) are functional. The transfer function is linear and ratiometric, with error budget dominated by linearity, T_COffset, and T_CSpan contributions.

Key Specifications

Pinout & Package

FAQ

What pressure type does MP3V5100GC6U measure?

The MP3V5100GC6U measures gauge pressure - meaning it reports pressure relative to ambient atmospheric pressure. Its single port (P1) is exposed to the measured medium, while the internal reference cavity is vented to atmosphere. This configuration is confirmed in the "Pressure (P1)/Vacuum (P2) Side Identification Table" and applies exclusively to the GC6U variant; it does not support differential or absolute modes. The MP3V5100GC6U must be mounted with the port side facing the pressure source and unobstructed airflow around the case.

What is the recommended decoupling network for MP3V5100GC6U?

The MP3V5100GC6U requires a specific decoupling network on its V_S pin to meet published accuracy specifications: a 1.0 μF bulk capacitor, a 0.01 μF ceramic capacitor, and a 470 pF capacitor placed as close as possible to pins 3 (GND) and 4 (V_S). This configuration is shown in Figure 3 of the official datasheet and is mandatory - omitting or substituting these values results in degraded noise immunity and increased error beyond ±2.5% VFSS. The MP3V5100GC6U will operate without it but fails to meet guaranteed performance.

Can MP3V5100GC6U be used with media other than dry air?

No - the MP3V5100GC6U is qualified and characterized exclusively for use with dry air as the pressure medium. Exposure to moisture, oils, solvents, or corrosive gases may degrade the fluorosilicone gel encapsulant, damage wire bonds, or cause long-term drift in offset and span. Freescale explicitly states that "media other than dry air may have adverse effects on sensor performance and long-term reliability." For non-dry-air applications, consult NXP (ex-Freescale) for qualified alternatives; the MP3V5100GC6U must not be deployed in such environments without formal media compatibility validation.

What is the meaning of "C6U" in MP3V5100GC6U?

The "C6U" suffix in MP3V5100GC6U denotes two specific attributes: "C6" indicates the Small Outline Package (Case 482A-01), and "U" specifies tape-and-reel packaging format (as opposed to "T1" for tape-and-reel with different reel specs or "P" for trays). This coding is defined in the Ordering Information table and confirms the device is supplied in 482A outline with standard carrier tape - critical for SMT placement equipment compatibility. The MP3V5100GC6U is not functionally distinct from MP3V5100GC6T1; only packaging differs.

Does MP3V5100GC6U require external calibration during system integration?

No - the MP3V5100GC6U is fully calibrated at the factory for offset, full-scale output, and temperature coefficients across 0–85°C. Its on-chip temperature compensation and signal conditioning eliminate the need for system-level calibration in most applications. However, final system validation is still required: users must verify linearity, warm-up behavior, and long-term stability under actual operating conditions. While the MP3V5100GC6U reduces calibration burden significantly, it does not remove the need for end-of-line functional testing per IEC 60601 or ISO 13485 where applicable.
