■General Description
■Features
The XC612 series consist of 2 voltage detectors, in 1 mini-molded, SOT-
25 package.
Highly accurate
: Set-up voltage accuracy 2ꢀ
Low-power consumption
Detect voltage
: Typ.2.0µA (VIN1=VIN2=2.0V, quiescent state)
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.
: 1.5V ~ 5.0V programmable in
0.1V steps. Detector’s voltages
can be set-up independently
Conditionaly,
The input (VIN1) for voltage detector 1 (VD1) dually functions as the power
supply pin for both detector 1 (VD1) and detector 2 (VD2).
