Analog Semiconductor IC
Low voltage, Low power, ±1% High detect accuracy CMOS Voltage Detector
VDA Series
GENERAL DESCRIPTIONS
The VDA series are 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.
