The VP811SEUS/T with SOT143-4 is a RoHS compliant electronic part manufactured by VP. It is a dual monitor reset device used in a variety of applications, such as port protection, over-voltage and inrush control, hot swapping, serial port protection, and network reset. It features an adjustable voltage threshold and wide input voltage range, plus dual green LEDs that indicate when the voltage is above or below the specified threshold. The chip is housed in a small 4-pin SOT143 package and is designed to be quick to trigger and have a fast response time.
