NXP Semiconductors MPXM2202GST1

Overview

MPXM2202GST1 from NXP Semiconductors (formerly Freescale) is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation, delivering a ratiometric 40 mV full-scale output at 10 V supply across 0–200 kPa range. It features ±0.4%VFSS linearity, ±0.1%VFSS pressure hysteresis, and operates from −40°C to +125°C. Used in medical diagnostics, level indicators, and pump/motor controllers where stable analog pressure feedback is required.

For engineers reviewing the MPXM2202GST1 datasheet, MPXM2202GST1 pinout, MPXM2202GST1 application, or MPXM2202GST1 equivalent, this page provides verified technical context, package mapping to CASE 1320A-02, confirmed pin assignments, real-world use scenarios, and two validated alternative parts for gauge-pressure sensing in industrial and medical systems.

Technical Context

The MPXM2202GST1 integrates a monolithic silicon diaphragm with laser-trimmed piezoresistive strain gauges and thin-film resistor networks for precision calibration. Its output voltage is directly proportional to applied differential pressure (P1 > P2), with offset and span calibrated over temperature using on-chip compensation circuitry.

It operates ratiometrically - output scales linearly with supply voltage (10 V typical, 16 V max) - and exhibits 1.0 ms response time (10%–90%), 6.0 mA supply current, and input/output impedances of 1–2.5 kΩ and 1.4–3.0 kΩ respectively. Designed for dry air media only.

Key Specifications

Pinout & Package

FAQ

What is the pressure type and range supported by MPXM2202GST1?

The MPXM2202GST1 is a gauge-pressure sensor with a specified range of 0–200 kPa (0–29 psi). It measures pressure relative to ambient atmospheric pressure via its ported P1 side, with P2 vented to atmosphere. This makes it appropriate for applications like liquid level sensing and HVAC duct monitoring where differential-to-ambient measurement is required. The device is not rated for vacuum or absolute pressure operation.

Does MPXM2202GST1 require external signal conditioning?

No, MPXM2202GST1 does not require external amplification or signal conditioning for basic operation. It delivers a ratiometric 40 mV full-scale differential output at 10 V supply, compatible with 12-bit or higher-resolution ADCs. However, designers may add an instrumentation amplifier if higher gain or single-ended conversion is needed. The sensor's built-in temperature compensation and laser-trimmed calibration eliminate the need for external trim components in most industrial implementations.

What is the correct pinout configuration for MPXM2202GST1?

MPXM2202GST1 follows Style 3 pinout per Freescale documentation: Pin 1 = GND, Pin 2 = −VOUT, Pin 3 = VS, Pin 4 = +VOUT. This matches the CASE 1320A-02 MPAK package layout. The pressure port is located on the side marked "P1", identified as the side with the port attached (per Table 3 in the datasheet). Proper orientation ensures accurate pressure coupling and avoids reversed differential polarity.

Can MPXM2202GST1 be used with supply voltages other than 10 V?

Yes, MPXM2202GST1 operates with supply voltages from 10 V to 16 V DC. Its output is ratiometric - meaning full-scale voltage scales linearly with supply voltage - so at 12 V supply, full-scale output becomes ~48 mV. Operating outside the 10–16 V range risks self-heating-induced errors or damage. For systems using 3.3 V or 5 V rails, an external regulator or charge pump is required; the device is not designed for low-voltage operation.

Is MPXM2202GST1 compatible with non-air pressure media?

No, MPXM2202GST1 is qualified and characterized exclusively for dry air as the pressure medium. Exposure to liquids, oils, corrosive gases, or high-humidity environments may degrade the silicone gel encapsulation or corrode internal metallization, leading to long-term drift or failure. For aggressive media, NXP recommends evaluating chemically resistant alternatives such as the MPX5050 series with stainless steel isolation or custom OEM packaging - MPXM2202GST1 itself is not rated for such use.
