■APPLICATIONS
■GENERAL DESCRIPTION
■FEATURES
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; VDFL (low when detected) and VDFH (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 VIN
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 Pin
: Watchdog input
If watchdog input maintains
‘H’ or ‘L’ within the watchdog
timeout period, a reset signal
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,
100msec, 50msec, 25msec,
3.13msec (TYP.) can be
selectable.
Watchdog Timeout Period : 1.6sec, 400msec, 200msec,
100msec, 50msec,
6.25msec (TYP.) can be
selectable.

XC6101~XC6107, XC6111~XC6117 Series
■OPERATIONAL EXPLANATION
The XC6101~XC6107, XC6111~XC6117 series compare, using the error amplifier, the voltage of the internal voltage
reference source with the voltage divided by R1, R2 and R3 connected to the VIN pin. The resulting output signal from the
error 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 VDFH type ICs.
<RESETB / RESET Pin Output Signal>
* VDFL (RESETB) type - output signal: Low when detected.
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 (TDR), and thereafter the RESET pin outputs high level signal.
* VDFH (RESET) type – output signal: High when detected.
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,
the VOUT pin output remains high for the release delay time (TDR), and thereafter the RESET pin outputs low level signal.
<Hysteresis>
When the internal comparator output is high, the NMOS transistor connected in parallel to R3 is turned ON, activating the
hysteresis circuit. The difference between the release and detect voltages represents the hysteresis range, as shown by the
following calculations:
VDF (detect voltage) = (R1+R2+R3) x Vref(R2+R3)
VDR (release voltage) = (R1+R2) x Vref(R2)
VHYS (hysteresis range)=VDR-VDF (V)
VDR > VDF
* Detect voltage (VDF) includes conditions of both VDFL (low when detected) and VDFH (high when detected).
* Please refer to the block diagrams for R1, R2, R3 and Vref.
Hysteresis range is selectable from VDF x 0.05V (XC6101~XC6107) or VDF x 0.001V (XC6111~XC6117).
<Watchdog (WD) Pin>
The XC6101~XC6107, 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 (TDR), and thereafter the
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 1.6sec, 400msec, 200msec, 100msec, 50msec,
6.25msec.
<MRB Pin>
Using the MRB 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 in the case of the VDFL type ICs, and the RESET pin output
goes from low to high in the case of the VDFH type. Even after the MRB pin is driven back high, the RESET/RESETB pin
output maintains the detection state for the release delay time (TDR). Since the MRB pin is internally pulled up to the VIN pin
voltage level, leave the MRB pin open if unused (Please refer to the FUNCTION CHART). A diode, which is an input
protection element, is connected between the MRB pin and VIN pin. Therefore, if the MRB pin is applied voltage that exceeds
VIN, the current will flow to VIN through the diode. Please use this IC within the stated maximum ratings (VSS -0.3 ~ VIN +0.3)
on the MRB pin.
<Release Delay Time>
Release delay time (TDR) is the time that elapses from when the VIN pin reaches the release voltage, or when the watchdog
timeout period expires with no rising signal applied to the WD pin, until the RESET/RESETB pin output is released from the
detection state. Seven release delay time (TDR) watchdog timeout period settings are available in 1.6sec, 400msec,
200msec, 100msec, 50msec, 25msec, 3.13msec.
<Detect Delay Time>
Detect Delay Time (TDF) is the time that elapses from when the VIN pin voltage falls to the detect voltage until the RESET/
RESETB pin output goes into the detection state.

■NOTES ON USE
1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent
damage to the device.
2. When a resistor is connected between the VIN pin and the input, the VIN voltage drops while the IC is operating and a
malfunction may occur as a result of the IC’s through current. For the CMOS output products, the VIN voltage drops while
the IC is operating and malfunction may occur as a result of the IC’s output current. Please be careful with using the
XC6111~XC6117 series (without hysteresis).
3. In order to stabilize the IC’s operations, please ensure that the VIN pin’s input frequency’s rise and fall times are more than
1 µ sec/V.
4. Noise at the power supply may cause a malfunction of the watchdog operation or the circuit. In such case, please
strength the line between VIN and the GND pin and connect about 0.22µF of a capacitor between the VIN pin and the GND
pin.
5. Protecting against a malfunction while the watchdog time out period, an ignoring time (no reaction time) occurs to the rise
and fall times. Referring to the figure below, the ignoring time (no reaction time) lasts for 900µsec at maximum.
