AnaSem VDD331MCTA

The VDD series are delay circuit built-in voltage detectors with low voltage, low power consumption and high accuracy. The accuracy of the detection voltage is detected based on a voltage reference of high accuracy that the temperature coefficient is controlled. The detection voltage is made in high accuracy by using the laser trimming technology. Because the delay circuit is built-in, delay time can be set without any external components.
