Pressure Freescale Semiconductor + MPX4100A Rev 9, 1/2009 Integrated Silicon Pressure Sensor for Manifold Absolute Pressure Applications On-Chip Signal Conditioned, Temperature Compensated and Calibrated The MPX4100A 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 MAP sensor a logical and economical choice for automotive system designers. The MPX4100A 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.

Device is ratiometric within this specified excitation range. 3. Offset (Voff) is defined as the output voltage at the minimum rated pressure. 4. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure. 5. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the minimum rated pressure. 6. Accuracy (error budget) consists of the following: Linearity: Temperature Hysteresis: Pressure Hysteresis: TcSpan: TcOffset: Variation from Nominal: Output deviation from a straight line relationship with pressure over the specified pressure range. Output deviation at any temperature within the operating temperature range, after the temperature is cycled to and from the minimum or maximum operating temperature points, with zero differential pressure applied. Output deviation at any pressure within the specified range, when this pressure is cycled to and from the minimum or maximum rated pressure, at 25C. Output deviation over the temperature range of 0 to 85C, relative to 25C. Output deviation with minimum rated pressure applied, over the temperature range of 0 to 85C, relative to 25C. The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS, at 25C. 7. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to a specified step change in pressure. 8. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized. 9. Offset Stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

A fluorosilicone gel isolates the die surface and wire bonds from the environment, while allowing the pressure signal to be transmitted to the sensor diaphragm. The MPX4100A series pressure sensor operating characteristics, and internal reliability and qualification tests are based on use of dry air as the pressure media. Media, other than dry air, may have adverse effects on sensor performance and long-term reliability. Contact the factory for information regarding media compatibility in your application. Figure 3 shows the recommended decoupling circuit for interfacing the output of the integrated sensor to the A/D input of a microprocessor or microcontroller. Proper decoupling of the power supply is recommended. 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 85C using the decoupling circuit shown in Figure 3. (The output will saturate outside of the specified pressure range.)

The Pressure (P1) side is the side containing fluorosilicone gel, which protects the die from harsh media. The MPX pressure Part Number sensor is designed to operate with positive differential pressure applied, P1 > P2. The Pressure (P1) side may be identified by using the following table: Case Type MPX4100A 867 Pressure (P1) Side Identifier Stainless Steel Cap MPX4100AP 867B Side with Part Marking MPX4100AS 867E Side with Port Attached MPXAZ4100A6U, MPXA4100A6U/TI 482 Side with Part Marking MPXAZ4100AC6U, MPXA4100AC6U 482A Side with Port Attached INFORMATION FOR USING THE SMALL OUTLINE PACKAGE (CASE 482) MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS Surface mount board layout is a critical portion of the total design. The footprint for the surface mount packages must be the correct size to ensure proper solder connection interface between the board and the package. With the correct footprint, the packages will self align when subjected to a solder reflow process. It is always recommended to design boards with a solder mask layer to avoid bridging and shorting between solder pads. 0.100 TYP 8X 2.54 0.660 16.76 0.060 TYP 8X 1.52 0.300 7.62 0.100 TYP 8X 2.54 inch mm SCALE 2:1 Figure 5.
