Si8751 Datasheet (Skyworks) - Isolated FET Driver

Si8751, Isolated FET Driver

Si8751/52 Data Sheet Isolated FET Driver with Pin Control or Diode Emulator Inputs The Si875x enables new pathways to the creation of custom Solid State Relay (SSR) configurations.

The Si875x integrates robust isolation technology with an SSR FET driver.

A floating secondary side dc power supply is unnecessary as the product generates its own self-contained gate drive output voltage.

When combined with a customer-selected external FET, a complete Solid State Relay is formed, allowing customers
