XC612 Series
2-Channel Voltage Detectors
ETR0204_002
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 (VIN1) for voltage detector 1 (VD1) dually functions as the power supply pin for both detector 1 (VD1) and detector 2
(VD2).
APPLICATIONS
Microprocessor reset circuitry
Memory battery back-up circuits
Power-on reset circuits
Power failure detection
System battery life and charge voltage monitors

(*1) The Features of output current, temperature characteristics and delay time are common between VDET1 and VDET2
Note:
VDF1(T), VDF2(T) : Nominal detect voltage.
Release voltage (VDR) = VDF +VHYS
N type Input Voltage : please ensure that VIN1 > VIN2
(Input voltage of XC612D and XC612E series : please ensure that VIN1 > VIN2, VIN1 < VIN2.)
VIN1 pin serve both ISS and power supply pin so that VIN2 operates VIN1 as a power supply source. For normal operation of VIN2,
operating voltage higher than the minimum is needed to be applied to power supply pin VIN1.
For CMOS output products, high level output voltage which is generated when the transient response is released becomes input
voltage of VIN.
