Eingangsspannung5 V
Schaltfrequenz250-620 kHz
Ausgang 16 V
IC-RevisionE1

Beschreibung

This reference design provides a simple means through which to isolate I2C or SPI type communication lines. This is often required in Grid Infrastructure applications such as, protertion relays and circuit breakers, where high voltages are involved. This reference design provides the complete solution in which, both power isolation and signal isolation is handled

Eigenschaften

  • Push-pull driver for small transformers
  • Single 3.3-V or 5-V supply
  • High primary-side current drive:
    • 5-V Supply: 350 mA (Max)
    • 3.3-V Supply: 150 mA (Max)
  • Low ripple on rectified output permits small outputcapacitors
  • Small 5-Pin SOT-23 Package

Typische Anwendungen

  • Isolated interface power supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, Low-Power LAN
  • Industrial automation / Process control
  • Medical equipment
