Silicon Labs SI8751AB-IS

容性耦合12500Vrms

Overview

Silicon Labs Si8751/52 Isolated FET Driver with Pin Control or Diode Emulator Inputs presents a simple way to create custom solid state relay (SSRs) configurations. The device combines robust isolation technology with an SSR FET driver. This forms a complete isolated switch with very efficient FET gate drive capability and robust isolation. Flexible outputs support driving AC or DC load configurations. Inputs provide digital CMOS pin control (Si8751) or diode emulation (Si8752) to appropriately suit the application. The drivers generate their own self-contained gate drive output voltage. This reduces the size, cost, and complexity. The Si8751/52 cancels the need for bulky mechanical relays. The design can be effectively optimized for the application, with the customer selecting their own flexible FET switch. The Si8751/52 drives FET gates with a nominal 10V, using a minimum 1mA input current.
