The XC6101~XC6105, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with
manual reset input 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 ~ XC6105, XC6111 ~
XC6117 series 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
(high when detected). With the XC6101 ~ XC6105, XC6111 ~ XC6115 series, 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
pin unconnected if the pin is unused. The detect voltages are internally fixed 1.6V ~ 5.0V in increments of 0.1V, using laser
trimming technology. Six watchdog timeout periods are available in a range from 6.25ms to 1.6s. Seven release delay times
are available in a range from 3.13ms to 1.6s.

■OPERATIONAL EXPLANATION
The XC6101~XC6105, XC6111~XC6117 series compare, using the amplifier, the voltage of the internal voltage reference
source with the voltage divided by R1, R2 and R3 connected to the V
amplifier activates the watchdog logic, manual reset logic, delay circuit and the output driver. When the VIN pin voltage
gradually falls and finally reaches the detect voltage, the RESETB pin output goes from high to low in the case of the VDFL type
ICs, and the RESET pin output goes from low to high in the case of the V
<RESETB / RESET Pin Output Signal>
DFL (RESETB) type - output signal: Low when detected.
* V
The RESETB pin output goes from high to low whenever the VIN pin voltage falls below the detect voltage, or whenever the
MRB pin is driven from high to low. The RESETB pin remains low for the release delay time (tDR) after the VIN pin voltage
reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period,
the RESETB pin output remains low for the release delay time (t
DFH (RESET) type – output signal: High when detected.
* V
The RESET pin output goes from low to high whenever the VIN pin voltage falls below the detect voltage, or whenever the
MRB pin is driven from high to low. The RESET pin remains high for the release delay time (tDR) after the VIN pin voltage
reaches the release voltage. If neither rising nor falling signals are applied to the WD pin within the watchdog timeout period,
OUT pin output remains high for the release delay time (tDR), and thereafter the RESET pin outputs low level signal.
the V
<Hysteresis>
When the internal comparator output is high, the N-Channel transistor connected in parallel to R3 is turned ON, activating the
hysteresis circuit. The difference between the release and detect voltages represents the hysteresis width, as shown by the
following calculations:
DF (detect voltage) = (R1+R2+R3) x Vref(R2+R3)
V
VDR (release voltage) = (R1+R2) x Vref(R2)
HYS (hysteresis width)=VDR-VDF (V)
V
VDR > VDF
* Detect voltage (VDF) includes conditions of both VDFL (low when detected) and VDFH (high when detected).
* Please refer to the block diagr ams for R1, R2, R3 and Vref.
Hysteresis width is selectable from V
<Watchdog (WD) Pin>
The XC6101~XC6105, XC6111~XC6117 series use a watchdog timer to detect malfunction or “runaway” of the
microprocessor. If neither rising nor falling signals are applied from the microprocessor within the watchdog timeout period,
the RESETB/RESET pin output maintains the detection state for the release delay time (t
RESET/RESETB pin output returns to the release state (Please refer to the FUNCTION CHART). The timer in the watchdog
is then restarted. Six watchdog timeout period settings are available in 1.6s, 400ms, 200ms, 100ms, 50ms, 6.25ms.
<MRB Pin>
Using the MRB voltage pin input, the RESET/RESETB pin signal can be forced to the detection state. When the MRB pin is
driven from high to low, the RESETB pin output goes from high to low level signal in the case of the V
RESET pin output goes from low to high in the case of the V
