NXP Semiconductors MP3V5004DP

Overview

MP3V5004DP from Freescale Semiconductor is a fully integrated, temperature-compensated and factory-calibrated differential pressure sensor with piezoresistive sensing element, 0–3.92 kPa (0–400 mm H₂O) range, 0.6–3.0 V ratiometric analog output, and ±2.5% full-scale span accuracy over 10°C to 60°C. It serves as a primary pressure transducer in microcontroller-based water level detection systems.

For engineers reviewing the MP3V5004DP datasheet, MP3V5004DP pinout, MP3V5004DP application, or MP3V5004DP equivalent, this page delivers verified package mapping (Case 1351), terminal roles, calibrated transfer function (V_OUT = V_S × [(0.2 × P) + 0.2] ± 2.5% VFSS), and validated alternatives for differential pressure sensing in consumer appliance control loops.

Technical Context

The MP3V5004DP integrates a monolithic silicon diaphragm with implanted strain gauge, thin-film metallization, and bipolar signal conditioning circuitry on a single die. Its on-chip temperature compensation operates across 10°C to 60°C, and calibration eliminates external zeroing requirements under stable thermal conditions.

It features differential port configuration (P1 > P2), ratiometric operation at 2.7–3.3 V_DC, and internal gain/offset trimming. Pins 1, 5, 6, 7, and 8 are no-connects; output is referenced to ground and supply voltage, enabling direct interface to 10-bit+ ADC inputs without external amplification.

Key Specifications

FAQ

What is the pressure port configuration of the MP3V5004DP?

The MP3V5004DP is a differential pressure sensor with two dedicated ports: P1 (pressure side, identified by part marking on Case 1351) and P2 (vacuum/reference side). It is specified for P1 > P2 operation only, and the internal transfer function assumes positive differential pressure. The fluorosilicone gel isolates the die on the P1 side, ensuring environmental protection while transmitting pressure accurately. MP3V5004DP does not support absolute or gauge configurations.

Does the MP3V5004DP require external zero calibration during system operation?

No, the MP3V5004DP is factory-calibrated and includes auto-zero reference storage. Its offset is trimmed at production, and the device subtracts the stored zero-pressure output during normal operation. However, optimal accuracy (±1.5% VFSS in 0–100 mm H₂O range) assumes thermal stability: the temperature difference between auto-zero event and measurement must not exceed ±5°C. MP3V5004DP does not require user-initiated zeroing unless thermal drift exceeds this threshold.

What is the recommended decoupling network for the MP3V5004DP power supply?

Freescale recommends a dual-stage decoupling network: a 1.0 μF bulk capacitor and a 0.01 μF ceramic capacitor placed as close as possible to pins 3 (GND) and 4 (V_S). An additional 470 pF capacitor may be added in parallel with the 0.01 μF part for enhanced high-frequency noise rejection. This configuration minimizes supply-induced errors and ensures stable operation of the on-chip signal conditioning circuitry in the MP3V5004DP.

Can the MP3V5004DP be used with media other than dry air?

The MP3V5004DP is qualified and characterized for dry air as the pressure medium. Use with other gases or liquids may affect long-term reliability, zero stability, and sensitivity due to chemical interaction with the fluorosilicone gel, stainless steel cap, or silicon diaphragm. Freescale explicitly states that non-dry-air media may degrade performance. If alternative media are required, consult NXP (successor to Freescale) for application-specific qualification data before deploying MP3V5004DP in production.

What is the meaning of "±2.5% VFSS" accuracy for the MP3V5004DP?

"±2.5% VFSS" means the total error budget-including linearity, temperature hysteresis, pressure hysteresis, offset stability, and TcOffset-is bounded within ±2.5% of the full-scale span voltage (VFSS ≈ 1.8 V at 3 kPa) across the 100–400 mm H₂O range and 10–60°C temperature band. This is not a tolerance on individual parameters but a composite specification covering all major error sources under defined operating conditions. MP3V5004DP achieves tighter ±1.5% VFSS in the lower 0–100 mm H₂O subrange.
