Integrated Silicon Pressure Sensor

Manifold Absolute Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The Motorola MPX4250 series Manifold Absolute Pressure (MAP) sensor for turbo

boost engine control is designed to sense absolute air pressure within the intake

manifold. This measurement can be used to compute the amount of fuel required for

each cylinder.

The MPX4250 series sensor integrates on–chip, bipolar op amp circuitry and thin film

resistor networks to provide a high level analog output signal and temperature

compensation. The small form factor and reliability of on–chip integration make the

Motorola MAP sensor a logical and economical choice for automotive system designers.

Features

• 1.5% Maximum Error Over 0° to 85°C

• Specifically Designed for Intake Manifold Absolute Pressure Sensing in Engine

Control Systems

• Ideally Suited for Direct Microprocessor Interfacing

• Patented Silicon Shear Stress Strain Gauge

• Temperature Compensated Over – 40° to +125°C

• Offers Reduction in Weight and Volume Compared to Existing Hybrid Modules

• Durable Epoxy Unibody Element

• Ideal for Non–Automotive Applications

Application Examples

• Manifold Sensing for Automotive Systems
