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.
