NXP Semiconductors MP3V5004GP

Overview

MP3V5004GP from Freescale Semiconductor is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.6–3.0 V analog output proportional to applied gauge pressure (0–3.92 kPa), operates from 2.7–3.3 V supply, draws ≤10 mA, and targets microcontroller-based water level sensing in appliances.

For engineers reviewing the MP3V5004GP datasheet, MP3V5004GP pinout, MP3V5004GP application, or MP3V5004GP equivalent, key selection criteria include its 0–400 mm H₂O range, ±1.5% VFSS accuracy at low pressure (0–100 mm H₂O), thermoplastic PPS package (Case 1369), and differential port configuration requiring correct P1/P2 side orientation during PCB layout.

Technical Context

The MP3V5004GP integrates a shear-stress strain gauge, thin-film temperature compensation network, and two-stage gain/offset circuitry onto a single die. Its transfer function is V_OUT = V_S × [(0.2 × P) + 0.2] ±2.5% VFSS, where P is pressure in kPa and V_S is supply voltage (3.0 V ±0.3 V).

It is ratiometric, meaning output scale and offset track supply voltage variation; operates over 0–85°C ambient but achieves specified accuracy only from 10–60°C; and requires dry air as pressure medium to maintain long-term reliability and calibrated performance.

Key Specifications

Pinout & Package

MP3V5004GP uses a thermoplastic PPS small-outline package (Case 1369), surface-mountable with 8 leads. Pins 1, 5, 6, 7, and 8 are No Connects; active terminals are Pin 2 (V_OUT), Pin 3 (GND), and Pin 4 (V_S). The pressure port is located on the side marked "Side with Port Attached" per Freescale's identification table.

FAQ

What is the pressure port configuration of the MP3V5004GP?

The MP3V5004GP features a differential pressure port configuration with designated Pressure (P1) and Vacuum (P2) sides. Per Freescale documentation, the P1 side is identified as "Side with Port Attached" for Case 1369. Correct orientation is essential: P1 must face the pressurized medium and P2 the reference (typically ambient or vacuum). Mounting with reversed sides causes inverted or saturated output.

Does the MP3V5004GP require external calibration or zeroing?

The MP3V5004GP is factory-calibrated and temperature-compensated, eliminating need for end-user calibration. However, Freescale recommends auto-zeroing in-system to cancel mounting-induced offset - storing the zero-pressure output at installation and subtracting it from subsequent readings. This step is critical for achieving ±1.5% VFSS accuracy in the 0–100 mm H₂O range, as specified in AN1636.

What is the recommended power supply decoupling for the MP3V5004GP?

Freescale specifies a decoupling network consisting of a 1.0 μF bulk capacitor, a 0.01 μF ceramic capacitor, and a 470 pF filter capacitor between V_S and GND, placed as close as possible to Pins 4 and 3. This configuration suppresses supply noise and prevents output ripple, especially important when interfacing with high-resolution ADCs. Failure to implement this network may degrade effective resolution and introduce measurement drift.

Can the MP3V5004GP be used with media other than dry air?

Freescale explicitly qualifies the MP3V5004GP for dry air only. Exposure to moisture, oils, solvents, or corrosive gases may degrade fluorosilicone gel integrity, cause wire bond corrosion, or shift calibration. For non-air media, users must contact NXP (ex-Freescale) for media compatibility testing data; no performance or reliability guarantees apply outside dry air operation.

What is the maximum operating pressure before damage occurs for the MP3V5004GP?

The MP3V5004GP has an absolute maximum pressure rating of 16 kPa (16000 mm H₂O) as defined in its Maximum Ratings table. Exceeding this value risks permanent mechanical deformation of the silicon diaphragm or bond wire failure. While the sensor operates linearly up to 3.92 kPa, transient spikes above 16 kPa - even briefly - may cause irreversible damage or calibration shift. System design must include overpressure protection.
