●High resolution 1D to 3D sensing

2-Tx and 4-Rx integrated antennas supporting TDM-MIMO operation realize 6x2 virtual antenna array

Wide bandwidth (6.8GHz max.) and high-accuracy linear chirp FMCW radar

Example of sensing target: infant lying in the child safety seat or persons sitting on the seat

●Highly integrated device enabling easy hardware design

Integrate radar signal processing unit (Distance/Angle/Presence detection), antennas, RF circuit, ADC, FIFO and SPI interface

Enable to use reasonable PCB, less BOM and easy assembly

Smallest package for all-in-one interior radio sensor (6.0mm x 9.0mm, BGA package)

●Low power consumption reducing battery load

4-level operation states (Shutdown, Deep Sleep, Light Sleep, Sensing)

Intelligent power control sequencer managing flexible duty cycle operation realize <1mW averaging power consumption

Activate other device by integrated presence detection functionality
