Evaluation Kit : 4 channels, 2MBps Isolated Data link

RHEA is  a high temperature data transmission solution with galvanic isolation of 2.5kV and operating reliably from -55°C to +225°C. 

The RHEA Evaluation Kit includes an Evaluation Board, the complete electrical schematic, the Gerber files, the bill of materials and an Application Note.

The Evaluation Board is built from a 200°C polyimide PCB, and it is populated with two instances of CHT-RHEA integrated circuits in ceramic packages guaranteed for -55°C up to +225C. The board allows short excursions to +200°C~225°C for testing. 

Typical performances:

  • Temperature range: -55°C to +175°C (and short excursion up to 225°C)
  • Power supply: 5V
  • Data rate up to 2 Mbits/sec per channel
  • Transmission delay below 100ns
  • Jitter lower than 21ns
  • Immunity to dV/dt : 50kV/µs.



  • Isolated gate drive for IGBT, MOSFET, JFET and SiC Transistors
  • Isolated sensor interfaces
  • Galvanic isolation of A-D converters
  • Galvanic isolation of standard RS-232 /
  • RS-422 / RS-485 / I2C transmission links
  • Industrial field bus isolation
  • Industrial power inverters
  • Motor drives and battery management in EV / HEV
