Si8752AB-IS Isolated FET Driver
The new Si8752AB-IS driver offers a simple way for customers to replace solid-state relays (SSRs) or electromechanical relays (EMRs). The Si8752AB-IS combines 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. The Si8752AB-IS eliminates the need for bulky mechanical relays which can be difficult to assemble onto PCBs and add switching noise to the system. The Si8752AB-IS supports 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. The 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. Further, its 2.5 kVrms isolation rating forms the basis for full certification to UL, CSA, VDE, and CQC.
