kp229e3111 analog absolute pressure sensor functional description data sheet 9 revision 1.0, 2012-07-27 2 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 algorit hm ? such as offset, gain, temperature coefficients of offset and gain, and linearization parameters ? are deter mined after assembly. the parameters are stored in an integrated e2prom. the e2prom content is protected wit h forward error correction (a one bit error is detected and corrected, errors of more than on e 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 si mplified and improved. open bond detection the open bond detection, in conjunction with the cl amping 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 trans istors of the broken wire detection stage are self- conducting. for example, if the gnd connection is interrup ted, the output is drawn strongly to vdd. similarly, if the vdd connection is broken, th e output is drawn to gnd.

kp229e3111 analog absolute pressure sensor functional description data sheet 13 revision 1.0, 2012-07-27 2.5 accuracy the accuracy of the kp229e3111 sensor is influenced by the supply voltage (ratiometric error) as well as by pressure, temperature and aging effects. the specified valu e, 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 (v out ) scales by the same ratio that v dd increases or decreases. the ratiometric error is defined as the difference between the ratio that v dd changed and the ratio that v out changed, expressed as a percentage. the output voltage v out is ratiometric to v dd . v dd must be in the operating range provided in table 7 . figure 4 ratiometric error 2.5.2 overall accuracy overall accuracy covers the entire pressure and temperat ure range from different sources of error including the following: ? pressure: output deviation from target transfer fu nction over the specified pressure range ? temperature: output deviation over the temperature range ? aging: parameter drift over life time table 3 ratiometric error supply voltage (v) max. ratiometric error ( e rat in % of v dd, typ ) v dd,min 0.5 v dd,typ 0 v dd,max 0.5 e rat (%) = v out (@v dd ) - v out (@5v) x 5v v dd 5v x 100% -0.5 0 v dd, min v dd 0.5 v dd, max v dd ,typ e rat (%)
