DESCRIPTION
ETR0209-009
Voltage Detector with Watchdog Function and ON/OFF Control (V
DF
=1.6V~5.0V)
The XC6121/XC6122/XC6123/XC6124 series are groups of high-precision, low current consumption voltage detectors with
watchdog functions incorporating CMOS process technology. The series consist of a reference voltage source, delay circuit,
comparator, and output driver. With the built-in delay circuit, the XC6121/XC6122/XC6123/XC6124 series’ ICs do not require
any external components to output signals with release delay time. The output type is V
DFL
low when detected. With the
XC6121/XC6122/XC6123/XC6124 series’ ICs, the EN/ENB pin can control ON and OFF of the watchdog functions. By setting
the EN/ENB pin to low or high level, the watchdog function can be OFF while the voltage detector remains operation. Since
the EN/ENB pin of the XC6122 and XC6124 series is internally pulled up to the V
IN
pin or pulled down to the V
SS
pin, the ICs
can be used with the EN/ENB pin left open, when the watchdog functions is used. The detect voltages are internally fixed
1.6V ~ 5.0V in increments of 100mV, using laser trimming technology. Six watchdog timeout period settings are available in a
range from 50ms to 1.6s. Five release delay time settings are available in a range from 3.13ms to 400ms.

Output Configuration
: N-channel open drain
Watchdog Pin
: Watchdog input
If watchdog input maintains ‘H’
or ‘L’ within the watchdog
timeout period, a reset signal is
output from the RESETB pin.
EN/ENB Pin
: When the EN/ENB pin voltage is
set to low or high level, the
watchdog function is forced off.
Release Delay Time
: 400ms, 200ms, 100ms, 50ms,
3.13ms (TYP.)
Watchdog Timeout Period
: 1.6s, 800ms, 400ms, 200ms,
100ms, 50ms (TYP.)
