Analog Absolute Pressure Sensor
1
Product Description
The KP229F3519 is a miniaturized Analog Manifold Air Pressure Sensor
IC based on a capacitive principle. It is surface micromachined with a
monolithic integrated signal conditioning circuit implemented in
BiCMOS technology.
The sensor converts a pressure into an analog output signal. The
calibrated transfer function converts a pressure of 50 kPa to 400 kPa into
a voltage range of 0.51 V to 4.55 V.
The chip is packaged in a “green” SMD housing. The sensor has been
primarily developed for measuring manifold air pressure, but can also be
used in other application fields. The high accuracy and the high
sensitivity of the device makes it a perfect fit for advanced automotive
applications as well as in industrial and consumer applications.

Analog Absolute Pressure Sensor
Functional Description

Functional Description
The pressure is detected by an array of capacitive surface micromachined sensor cells. The sensor cell output is
amplified, temperature compensated and linearized to obtain an output voltage that is proportional to the applied
pressure.
The transfer function for linearization is computed in the digital part of the sensor using a third order polynomial
calculation. The transfer function is created from the following parameters:
•
Minimum and maximum rated pressure
•
Voltage level at minimum and maximum rated pressure
•
Clamping levels
The output is analog and ratiometric with respect to the supply voltage.
All parameters needed for the complete calibration algorithm — such as offset, gain, temperature coefficients of
offset and gain, and linearization parameters — are determined after assembly. The parameters are stored in an
integrated E²PROM. The E²PROM content is protected with forward error correction (a one bit error is detected
and corrected, errors of more than one bit are detected and the output signal is switched to ground potential).
Clamping
The output voltage is limited internally to two clamping threshold levels. Based on this feature, the open bond
detection (OBD) is simplified and improved.
Open Bond Detection
The open bond detection, in conjunction with the clamping levels, eases the implementation of error and
malfunction detection strategies (e.g. for On-Board Diagnosis requirements). The microcontroller can sample the
output of the sensor and compare it with programmed overvoltage and undervoltage limits. When the sensor’s
output voltage exceeds those limits, a broken wire condition is identified.
When the chip is not powered properly, the JFET transistors of the broken wire detection stage are self-conducting.
For example, if the GND connection is interrupted, the output is drawn strongly to VDD. Similarly, if the VDD
connection is broken, the output is drawn to GND.

Transfer Function
The KP229F3519 device is fully calibrated on delivery. The sensor has a linear transfer function between the
applied pressure and the output signal:
V OUT = VDD x (a x P + b)
The output signal is ratiometric. Gain a and offset b are determined during calibration in order to generate the
required transfer function.
Calibrated Transfer Function
The following calibration is adjusted with the parameters a and b:

Accuracy
The accuracy of the KP229F3519 sensor is influenced by the supply voltage (ratiometric error) as well as by
pressure, temperature and aging effects. The specified value, calculated with the transfer function, represents the
theoretical value (see Figure 3). The error equals the deviation between the measured output voltage value and the
specified output voltage value.
2.5.1
Ratiometric Error
Ideally the sensor is ratiometric - the output (VOUT) scales by the same ratio that VDD increases or decreases. The
ratiometric error is defined as the difference between the ratio that VDD changed and the ratio that VOUT changed,
expressed as a percentage.
ERAT (%) =
VOUT(@VDD) - V OUT(@5V) x
5V
VDD

x 100%
The output voltage VOUT is ratiometric to VDD. VDD must be in the operating range provided in Table 7.

Application Circuit Example
It is recommended to protect the pressure sensor IC against overload and electro-magnetic interferences (as shown
in Figure 10.
The output circuit acts as a low-pass decoupling filter between the sensor IC output and the A/D input of the
microcontroller.
The shown application circuit example considers an increased cable length between the sensor and the
microcontroller. A combined location on a PCB with reduced distance between the sensor and the controller
allows a reduction of the numbers of the passive components (e.g. C2, R1 and R2 can be omitted).

Attention: Stresses above the max. values listed in Table 6 may cause permanent damage to the device.
Exposure to absolute maximum rating conditions for extended periods may affect device
reliability. Maximum ratings are absolute ratings; exceeding only one of these values may cause
irreversible damage to the integrated circuit.
