Si8751/52 Data Sheet
Isolated FET Driver with Pin Control or Diode Emulator Inputs
The Si875x enables new pathways to creating custom solid state relay (SSR) configurations. Supporting customer-selected external FETs, the Si875x combines robust isolation technology with an SSR FET driver to form a complete, isolated switch. Versatile inputs provide digital CMOS pin control (Si8751) or diode emulation (Si8752) to best suit the application, plus flexible outputs to support driving ac or dc load configurations. A floating secondary side dc voltage source is unnecessary as the product generates its own self-contained gate drive output voltage, reducing cost, size, and complexity.
