Si8751AB-AS

Isolated FET Drivers

Si8751AB-AS automotive FET drivers offer a simple way to replace solid-state relays (SSRs) or electromechanical relays (EMRs). Combining a robust CMOS isolation technology with a FET driver, the devices 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 self-contained product generates its own gate drive output voltage, reducing cost, size, and complexity. Si8751AB-AS devices eliminate the need for bulky mechanical relays which can be difficult to assemble onto PCBs and add switching noise to the system. Input side voltages are flexible from 2.25 V to 5.5 V supporting seamless connection to low-power controllers. The Si8751AB-AS is fully automotive qualified and its 2.5 kVrms isolation rating forms the basis for full certification to UL, CSA, VDE, and CQC.
