NXP Semiconductors MPXV5100DP

Overview

MPXV5100DP from NXP Semiconductors is a monolithic silicon differential pressure sensor in an 8-lead small outline package, delivering ratiometric analog output (0.2–4.8 V) over 0–100 kPa range at 5 V supply, with ±2.5% full-scale accuracy across 0–85 °C and 1 ms response time - used in medical patient monitoring, industrial pump control, and white goods pressure switching.

For engineers reviewing the MPXV5100DP datasheet, MPXV5100DP pinout, MPXV5100DP application, or MPXV5100DP equivalent, key selection criteria include its dual-port differential configuration, on-chip temperature compensation, 45 mV/kPa sensitivity, and compatibility with microcontroller A/D inputs without external signal conditioning.

Technical Context

The MPXV5100DP integrates a piezoresistive sensing element with thin-film metallization and bipolar processing to generate a linear, temperature-compensated analog voltage output proportional to applied differential pressure. Its internal architecture includes two gain stages and ground-reference shift circuitry, enabling stable operation from -40 to +125 °C.

It operates ratiometrically with supply voltage (4.75–5.25 V), exhibits 7 mA typical supply current, and features fluorosilicone gel isolation of the die for environmental protection while transmitting pressure to the diaphragm - designed specifically for dry air media applications.

FAQ

What is the pressure port configuration of the MPXV5100DP?

The MPXV5100DP features a dual-port differential configuration with separate pressure inlets labeled P1 and P2. Per NXP documentation, the P1 side is identified by the part marking on the package, and P1 > P2 defines positive differential pressure operation. The ports are located on opposite sides of the 8-lead small outline package (case 98ASA99255D), enabling true differential measurement without external manifolds. This arrangement is confirmed in the package identification table and cross-sectional diagrams of the MPXV5100DP datasheet.

Does the MPXV5100DP require external calibration or signal conditioning?

No, the MPXV5100DP does not require external calibration or signal conditioning. It integrates on-chip temperature compensation and factory calibration for offset and full-scale span across 0–85 °C, delivering a ratiometric analog output (0.2–4.8 V) that directly interfaces with standard 5 V microcontroller ADCs. The datasheet specifies ±2.5% VFSS accuracy without additional components, and Figure 7 shows only passive decoupling (0.01 µF + 1.0 µF capacitors) is needed at VS and VOUT.

What is the maximum pressure rating and overpressure tolerance of the MPXV5100DP?

The MPXV5100DP has a rated pressure range of 0–100 kPa differential, with a maximum pressure rating of 400 kPa as specified in Table 3 of the MPX5100 datasheet. Exceeding 400 kPa may cause permanent damage or degradation. The sensor is qualified for long-term reliability under pulsed pressure testing and exhibits ±0.5% VFSS offset stability after 1000 hours of such stress - confirming robustness well beyond its operational range.

Can the MPXV5100DP be used with supply voltages other than 5 V?

Yes, the MPXV5100DP operates ratiometrically within a supply voltage range of 4.75–5.25 V DC, as defined in Table 4 of the datasheet. Its output voltage scales linearly with VS, so deviations within this window maintain accuracy without recalibration. Operation outside this range is not characterized and may compromise performance or reliability; the device is not rated for 3.3 V operation, and using voltages below 4.75 V risks violating minimum operating specifications.

Is the MPXV5100DP compatible with media other than dry air?

No - the MPXV5100DP is qualified and characterized exclusively for use with dry air as the pressure medium. NXP explicitly states that other media "may have adverse effects on sensor performance and long-term reliability." Fluorosilicone gel isolates the die, but chemical compatibility is not guaranteed for liquids, oils, or humid gases. For non-dry-air applications, users must contact NXP directly for media compatibility testing data before deployment.
