Renesas RAA2S4251 | Demoboard RAA2S425X Evaluation Board
Automotive Sensor Signal Conditioner with Analog Output
Overview
| Topology | Sensors |
| IC revision | 6 |
Description
The RAA2S4251B is a member of Renesas’ family of CMOS integrated circuits for highly accurate amplification and sensor-specific correction of differential bridge sensor signals. Featuring a maximum analog pre-amplification of 900 with analog sensor offset correction (XSOC), the RAA2S4251B is adjustable to nearly all resistive bridges.Conditioning calculation is accomplished via a 16-bit RISC microcontroller. Calibration coefficients and configuration data are stored in the nonvolatile memory (NVM), which is reliable in automotive applications.
Features
- Capable of measuring one full resistive bridge sensor signals
- Temperature measurement using external diode/PTC/TCR or internal (PTAT) sensor
- Large sensor offset correction using analog offset compensation and digital zooming with up to 18-bit resolution
- Higher digital resolution, fast OUR output update rate by ADC & sharp roll-off by digital LPF
- Ability to cover large sensor span & high accuracy (0.35% - 1.0%) over the entire temp. range (-40°C to 150°C)
- Qualified according to AEC-Q100 Grade 0
- Optimized for harsh automotive environment
- Over-voltage and reverse polarity protection ±40V, robust EMC performance, and multiple diagnostic features
- Minimal EOL (end-of-line) production costs during mass production
- QFN-24 as package option
- Analog output
Typical applications
- Plug-in hybrid electric vehicle (PHEV) Battery electric vehicle (BEV) Fuel-cell electric vehicle (FCEV)
- Pressure sensing in braking, transmission and HVAC applications xEV
