GENERAL DESCRIPTIONS

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.
