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.
