Voltage Detector with Watchdog Function and ON/OFF Control (VDF=1.6V~5.0V)
■GENERAL DESCRIPTION
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 VDFL 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 VIN pin or pulled down to the VSS 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.

■OPERATIONAL EXPLANATION
The XC6121/6122/6123/6124 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, 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.
<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. 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.
<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 width, as shown by the
following calculations:
VDFL (detect voltage) = (R1+R2+R3) x Vref / (R2+R3)
VDR (release voltage) = (R1+R2) x Vref / (R2)
VHYS (hysteresis width) =VDR-VDFL (V)
VDR > VDFL
* Please refer to the block diagrams for R1, R2, R3 and Vref.
* Hysteresis width is selectable from VDFL x 0.05V (TYP.).
<Watchdog (WD) Pin>
The 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 pin output maintains the detection state
for the release delay time (TDR), and thereafter the RESETB pin outputs low to high signal. The watchdog pin is pulled down
to the VSS internally. When the watchdog pin is not connected, A reset signal comes out after the watchdog timeout period.
Six watchdog timeout period settings (TWD) are available in 1.6s, 800ms, 400ms, 200ms, 100ms, and 50ms.
<EN Pin>
In case where the watchdog function is not used, When the EN pin input driven to low level, only the watchdog function is
forced off while the detect voltage circuit remains operation. For using the watchdog function, the EN pin should be used in
high level. Even after the input voltage and the EN pin voltage are driven back high, the RESETB pin output maintains the
detection state for the release delay time (TDR). (Refer to the TIMING CHART 1-①.) The watchdog function recovers
immediately when the input voltage becomes higher than the release voltage and the EN pin voltage driven from low to high
level. (Refer to the TIMING CHART 1-②.) A diode, which is an input protection element, is connected between the EN pin
and VIN pin. Therefore, if the EN pin is applied voltage that exceeds VIN, the current will flow to VIN through the diode. For
avoiding any damage to the IC, please use this IC within the stated maximum ratings (VSS -0.3 ~ VIN +0.3) on the EN pin.
<ENB Pin>
In case where the watchdog function is not used, when the ENB pin input driven to high level, only the watchdog function is
forced off while the detect voltage circuit remains operation. For using the watchdog function, the ENB pin should be used in
low level. Even after the input voltage and the ENB pin voltage are driven back low, the RESETB pin output maintains the
detection state for the release delay time (TDR). (Refer to the TIMING CHART 2-①.) The watchdog function recovers
immediately when the input voltage becomes higher than the release voltage and the ENB pin voltage driven from high to low
level. (Refer to the TIMING CHART 2-②.) A diode, which is an input protection element, is connected between the ENB pin
and VIN pin. Therefore, if the ENB pin is applied voltage that exceeds VIN, the current will flow to VIN through the diode. For
avoiding any damage to the IC, please use this IC within the stated maximum ratings (VSS -0.3 ~ VIN +0.3) on the ENB 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 RESETB pin output is released from the detection
state. Five release delay time (TDR) watchdog timeout period settings are available in 400ms, 200ms, 100ms, 50ms, and
3.13ms.
<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 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.
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 s/V.
4. Noise at the power supply may cause a malfunction of the watchdog operation or the voltage detector. 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 900μs at maximum.
6. The EN pin of the XC6121 series is not internally pulled up. When using the watchdog function, please drive the EN pin in
high level. The EN pin of the XC6122 series is internally pulled up. The watchdog function can be used even the EN pin
left open. The ENB pin of the XC6123 series is not internally pulled down. When using the watchdog function, please
drive the ENB pin in low level. The ENB pin of the XC6124 series is internally pulled up. The watchdog function can be
used even the ENB pin left open.
