The XC6101~XC6107, XC6111~XC6117 series are
groups of high-precision, low current consumption voltage
detectors with manual reset input function and 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 XC6101 ~ XC6107,
XC6111 ~ XC6117 series’ ICs do not require any external
components to output signals with release delay time.
Moreover, with the manual reset function, reset can be
asserted at any time. The ICs produce two types of
output; V
DFL
(low when detected) and V
DFH
(high when
detected).
With the XC6101 ~ XC6105, XC6111 ~ XC6115 series’
ICs, the WD pin can be left open if the watchdog function
is not used.
Whenever the watchdog pin is opened, the internal
counter clears before the watchdog timeout occurs.
Since the manual reset pin is internally pulled up to the V
IN
pin voltage level, the ICs can be used with the manual
reset pin left unconnected if the pin is unused.
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 6.25msec to 1.6sec.
Seven release delay time 1 are available in a range from
3.13msec to 1.6sec.

: Watchdog input
If watchdog input maintains
‘H’ or ‘L’ within the watchdog

is output to the RESET
output pin
Manual Reset Pin
: When driven ‘H’ to ‘L’ level
signal, the MRB pin voltage
asserts forced reset on the
output pin.
Release Delay Time
: 1.6sec, 400msec, 200msec,
