Automotive Capacitive Pressure Sensor Reference Design
Description
The TIDA-00985 reference design provides a simple: robust: and accurate sensor signal conditioning solution using the PGA400-Q1 for capacitive type pressure sensors. The protection strategies implemented in this design protect the pressure sensor against wiring harness faults: EMI: and automotive electrical transients. Additionally: this design guide systematically explains the theory: operation: and challenges involved in the design.
Features
- Accuracy of 0.25% over temperature (-40 °C to 125 °C)Second order temperature and linearity compensation algorithmForm factor design of 18.6mm diameterProtection against harness faults (over voltage and reverse polarity protection): broken wire detectionMeets ISO7637-3 requirements for transient pulses: tested for bulk current injection (BCI)-ISO11452-4
