Si8752AB-IS

Si875x Isolated FET Driver

Si8752AB-IS drivers offer a simple way for customers to replace solid-state relays (SSRs) or electromechanical relays (EMRs), combining robust CMOS isolation technology with a 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 self-contained product generates its own gate drive output voltage, reducing cost, size, and complexity. Si8752AB-IS devices eliminate the need for bulky mechanical relays which can be difficult to assemble onto PCBs and add switching noise to the system. Si8752AB-IS drivers support full industrial and automotive temperature ranges with increased stability and longer life-time. Input side voltages are flexible from 2.25 V to 5.5 V supporting seamless connection to low-power controllers. Si8752AB-IS devices provide a clamping device to prevent unintended turn on of the external FET when a high dV/dt is present on the FET’s drain, and its 2.5 kVrms isolation rating forms the basis for full certification to UL, CSA, VDE, and CQC.
