Overview

The MPX4250A/MPXA4250A Manifold Absolute Pressure (MAP) sensor for enginecontrol is designed to sense absolute air pressure within the intake manifold. Thismeasurement can be used to compute the amount of fuel required for each cylinder.The MPX4250A/MPXA4250A piezoresistive transducer is a state-of-the-art monolithicsilicon pressure sensor designed for a wide range of applications, particularly thoseemploying a microcontroller or microprocessor with A/D inputs. This transducer combinesadvanced micromachining techniques, thin-film metallization, and bipolar processing toprovide an accurate, high-level analog output signal that is proportional to the appliedpressure. The small form factor and high reliability of on-chip integration make the NXPsensor a logical and economical choice for the automotive system engineer.

Features

  • Up to 1.5% error in the range of 0°C to 85°C
  • Specially designed for intake manifold. absolute pressure detection in engine control systems.
  • Patented silicon shear stress strain gauge.
  • Temperature compensation from -40 °C to 125 °C is possible.
  • Weight and volume can be reduced compared to existing hybrid modules.
  • Durable epoxy resin unibody elements or thermoplastic resin small surface mount packages are used.
  • Ideal for non-automotive applications.
  • Three types of small outline packages and two types of unibody packages are available.

Application

  • Turbo Boost Engine Control
  • It is ideal for microprocessor and microcontroller based systems.
