SBT3000

Silicon Brite

The SBT3000 is a patented, autonomous high voltage AC switch controller device, which monitors incoming line voltage to ensure that the downstream load only operates within its safe maximum continuous voltage ratings. In the event of over-voltage line conditions, the SBT3000 will automatically disable the AC switch to protect and isolate the load and minimize the potential of catastrophic failure modes. The SBT3000 Evaluation Module (EVB), is an engineering circuit board designed for testing the operation of the SBT3000 integrated circuit. The SBT3000 EVB contains an SO8 IC socket and all the necessary support components to be able to apply an input voltage and a moderate load in order to evaluate the overvoltage protection features of the device.

Simplified circuit diagram for SBT3000 application.

The SBT3000 IC detects an overvoltage condition and turns off the downline load for the duration of the overvoltage condition. The SBT3000 can be used in conjunction with a varistor to provide superior unmatched line voltage protection. Customers will appreciate the additional reliability of the SBT3000 solution, which will ensure robust and uninterrupted long-term reliable operation of their product.
