Product Information

SI8751AB-IS Silicon Labs, Gate Driver Capacitive Coupling 2500Vrms 1 Channel 8-SOIC

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. 

The Si875x eliminates the need for bulky mechanical relays which can be difficult to assemble onto PCBs and add switching noise to the system. Further, with the customer selecting their own flexible FET switch, the design can be completely optimized for the application's power, cost, and performance requirements. Traditional SSRs also integrate optocouplerstyle LED inputs, which limit the operating temperature range of the solution, but the Si875x, with its input diode emulator or digital input control, experiences no such limitation and can support full industrial and automotive temperature ranges with increased stability and longer life.
