The Motorola MPX4101 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 Motorola MAP
sensor a logical and economical choice for automotive system designers.

The MPX4101 series piezoresistive transducer is a state–
of–the–art, monolithic, signal conditioned, silicon pressure
sensor. This sensor, with its patented transducer, 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.
Figure 1 shows a block diagram of the internal circuitry integrated on a pressure sensor chip.

MECHANICAL CHARACTERISTICS
Characteristic
NOTES:
1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. 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:
Output deviation from a straight line relationship with pressure over the specified pressure range.
• Temperature Hysteresis: 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.
• Pressure Hysteresis:
Output deviation at any pressure within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
• TcSpan:
Output deviation over the temperature range of 0 to 85°C, relative to 25°C.
• TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 0 to 85°C, relative
to 25°C.
• Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS, at 25°C.
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 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.
10. Common mode pressures beyond specified may result in leakage at the case–to–lead interface.

Figure 3. Decoupling Filter for Sensor to
Microprocessor Interface
Figure 2 illustrates an absolute sensing chip in the basic
chip carrier (Case 867). 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 MPX4101A 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 a typical decoupling circuit for interfacing
the integrated MAP sensor to the A/D input of a microprocessor. Proper decoupilng 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
85°C. (The output will saturate outside of the specified pressure range.)

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Motorola designates the two sides of the pressure sensor
as the Pressure (P1) side and the Vacuum (P2) side. The
Pressure (P1) side is the side containing fluorosilicone gel
which protects the die from harsh media. The Motorola MPX
Part Number
pressure sensor is designed to operate with positive differential pressure applied, P1 > P2.
