Compensated and Calibrated

The Freescale MPX4101A/MPXA4101A/MPXH6101A series Manifold

Absolute Pressure (MAP) sensor for 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 small form factor

and high reliability of on-chip integration makes the Freescale MAP sensor a

logical and economical choice for automotive system designers.

The MPX4101A/MPXA4101A/MPXH6101A series piezoresistive transducer

is a state-of-the-art, monolithic, signal conditioned, silicon pressure sensor. This

sensor combines advanced micromachining techniques, thin film metallization,

and bipolar semiconductor processing to provide an accurate, high level analog

output signal that is proportional to applied pressure.

Features

• 1.72% Maximum Error Over 0° to 85°C

• Specifically Designed for Intake Manifold Absolute Pressure Sensing in

Engine Control Systems

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

• Durable Epoxy Unibody Element or Thermoplastic (PPS) Surface Mount Package

Typical Applications

• Manifold Sensing for Automotive Systems

• Ideally Suited for Microprocessor or Microcontroller-Based Systems

• Also Ideal for Non-Automotive Applications

ON-CHIP TEMPERATURE COMPENSATION AND CALIBRATION Figure 2 illustrates an absolute sensing chip in the super small outline package (Case 1317). Figure 4 shows the sensor output signal relative to pressure input. Typical, minimum, and maximum output curves are shown for operation over a temperature range of 0° to 85°C. The output will saturate outside of the specified pressure range.

INFORMATION FOR USING THE SMALL OUTLINE PACKAGES MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS Surface mount board layout is a critical portion of the total footprint, the packages will self align when subjected to a design. The footprint for the surface mount packages must be solder reflow process. It is always recommended to design the correct size to ensure proper solder connection interface boards with a solder mask layer to avoid bridging and between the board and the package.
