Isolation Transformer

for Texas Instruments SN6501 and SN6505B Push-Pull driver

RoHS準拠 ハロゲンフリー AEC-Q flag
Coilcraft's UA825x miniature, low-profile transformers are designed for use with SN6501 and SN6505B transformer drivers from Texas Instruments. The center-tapped push-pull transformer features high isolation voltage and high efficiency for isolated power supplies. 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.
  • 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 qualified

メモ
  1. Inductance is for primary windings measured between pin 1 and 3 at 10 kHz, 0.05 Vrms, 0 Adc.
  2. Leakage inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms with secondary pins shorted.
  3. Volt-time product is for the primary, between pin 1 and 3.
  4. One minute isolation (hipot) primary windings to secondary windings.
