Sensor specialist Melexis came to Electronica 2012 to roll out two
new products to make the design for two crucial aspects of the car
much more intelligent and robust.
Peter Riendeau, a longtime sensor-technology observer and now
general manager at Melexis, talked
with EE Times Brand Manager Alexander Wolfe about the
company's new MLX90809 integrated pressure sensor, which targets
power assist braking.
"It's used in a stop-and-go system," Riendeau said. "So (with) the
new cars, you pull up to a stop sign engine shuts down. You still
need to know if there's vacuum pressure the brakes."
Here are some of the product's
MEMS Relative Pressure Sensor
- Pressure and Vacuum
- 1 Bar Full Scale
- Analog output or SENT Protocol
Integrated Signal Processing
- 16-Bit ADC
- 16-Bit MCU EEPROM Configurable
- Temperature Compensation
- Onboard Diagnostics
Riendeau also described an interesting new LIN bus driver for LEDS,
Here's Riendeau describing the products and the challenges of
automotive design in the future as engineers debate moving from
12-volt systems to 48.
