It is driven by the SN6505B from a 3.3 V or 5.0 V power supply and provides high isolation at 2500 Vrms across the isolation barrier for interfaces such as CAN, RS-485, RS-422, RS-232, SPI, I2C , and low-power LAN in industrial and automotive applications.

The UA825x is AEC Grade 1 qualified, making it an ideal solution for DC-DC converters in EV/HEV applications.

Features

  • Developed for Texas Instruments SN6501 and SN6505B Push-Pull driver
  • Low profile and center-tapped push-pull transformers for isolated power supply
  • 2500 Vrms, one minute high isolation (hipot) winding to winding
  • AEC-Q200 Grade 1 (–40°C to +125°C)
  • Core material Ferrite
  • Terminations RoHS tin-silver-copper over tin over nickel over phosphor bronze.
  • Weight 0.3 – 0.4 g
  • Ambient temperature –40°C to +125°C
  • Maximum part temperature +165°C (ambient + temp rise)
