Integrated Silicon Pressure Sensor

for Manifold Absolute Pressure

Applications

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The Motorola 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 Motorola 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.

Figure 1 shows a block diagram of the internal circuitry integrated on a pressure

sensor chip.

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

Application Examples

• Manifold Sensing for Automotive Systems

• Ideally Suited for Microprocessor or Microcontroller–Based Systems

• Also Ideal for Non–Automotive Applications
