XC612
Series
2-Channel Voltage Detectors
ETR0204_001
■GENERAL
DESCRIPTION
The XC612 series consist of 2 voltage detectors, in 1 mini-molded, SOT-25 package.
The series provides accuracy and low power consumption through CMOS processing and laser trimming and consists of a
highly accurate voltage reference source, 2 comparators, hysteresis and output driver circuits.
The input (V
IN1
) for voltage detector 1 (V
D1
) dually functions as the power supply pin for both detector 1 (V
D1
) and detector 2
(V
D2
).
