KP215F1701
Analog Absolute Pressure Sensor
Product Description
KP215F1701
1
Product Description
The KP215F1701 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 10 kPa to 115 kPa into
a voltage range of 0.4 V to 4.65 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.

KP215F1701
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 selfconducting. 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 KP215F1701 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 KP215F1701 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.
VOUT(@VDD) - V OUT(@5V) x
ERAT (%) =
5V
VDD
5V
x 100%
The output voltage VOUT is ratiometric to VDD. VDD must be in the operating range provided in Table 7.

Power-up Time
The power-up time tUP is defined as the maximum time between the supply voltage reaching its operating range
and the output voltage reaching 90% of its final value (assuming pin VOUT open and constant input pressure).

Response Time and Stabilization Time
The response time tR is defined as the time required by the output to change from 10% to 90% of its final value
after a specified pressure step (assuming pin VOUT open).
The stabilization time tS is defined as the time required by the output to meet the specified accuracy after the
pressure has been stabilized (assuming pin VOUT open).

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).

Application circuit example
Note: It is recommended to leave the digital pins CLOCK/VPROG, DATA IN and DATA OUT floating (in case of an
open GND connection, the floating pins prevent from a cross grounding through the corresponding ESD
diodes).

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.

2) More details in section “Timing Properties” on Page 16
3) The maximum response time considers a maximal value of 100nF for the output blocking capacitor C2 and a maximum
pressure pulse equivalent 4.0V output change
4) In the event of a broken wire (broken VDD line or broken GND line), the output changes to certain voltage levels within the
broken wire response time. The OBD ranges are determined by the application circuitry
