■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
).
