product brief application the manifold air pressure (map) is an important parameter to compute the air- fuel ratio provided to the engine for lower emission due to better combustion and increased effciency. for cost sensitive engine systems a map sensor show the potential to complement or even substitute mass air fow (maf) sensors. in addition manifold pressure data can be used to compute diagnostics of leakages and malfunctions of the exhaust gas recirculation valve. in automotive applications where high production volumes are common there is substantial interest in precision, low-cost and fully integrated sensors. in this context products of the developed map sensor family KP21X are the optimum solution for aspirated or turbo diesel and gasoline engines management systems. features absolute air pressure measurement excellent accuracy of up to 1.0 kpa over a large temperature range ratiometric analog output output signal fully compensated pressure range from 15 to 150 kpa temperature range (ambient) from -40 to +140c smd package (pg-dsof-8-16) output clamping (optional for kp216) complete product family (kp214, kp215, kp216) application circuit for the pressure sensor system ? ? ? ? ? ? ? ? ? w w w . i n f i n e o n . c o m / s e n s o r s typical application engine control/map applications industrial controls ? ? sensors KP21X/map integrated pressure sensor ic for manifold air pressure measurement applications 1 5 2 t est v dd c 1 r 1 *) 7 v out 6 gnd *) r 1 and r 2 only alternatively 8 gnd cl ock/ v prog KP21X re f gnd a/d in microc ontrolle r adc 3 da ta in 4 da ta out c 3 c 2 5 v r 2 *) r 3 map module electr onic c ontr ol unit (e cu ) a/d in t- sensor
