Automotive Resistive Bridge Pressure Sensor Reference Design
Overview
| Topology | Other Topology |
| Input voltage | 5-20 V |
| Output 1 | 20 V |
| IC revision | A |
Description
The TIDA-00793 reference design provides a simple, robust, and accurate sensor signal conditioning solution using the PGA301-Q1 for resistive bridge type pressure sensors. The protection strategies implemented in this design protect the pressure sensor against wiring harness faults, EMI, and automotive electrical transients. Theory, operation, and challenges involved in the design are systematically explained in the design guide.
Features
- Accuracy of 0.17% Over Temperature(–40°C to 125°C)
- Second Order Temperature and LinearityCompensation Algorithm
- Form Factor Design of 23 × 23 mm
- Protection Against Harness Faults (Overvoltageand Reverse Polarity Protection), Broken WireDetection
- Meets ISO 7637-3 Requirements for TransientPulses
- Tested for Bulk Current Injection (BCI)ISO 11452-4
Typical applications
- Pedal Force
- Engine Oil Pressure
- In-Cylinder Pressure
- Occupant Weight
- HVAC Compressor Pressure
- EGR Pressure
- Transmission Oil Pressure
- Manifold Absolute Pressure
