Voltage Detector with Separated Sense Pin & Delay Capacitor Pin
■GENERAL DESCRIPTION
The XC6118 series is a low power consumption voltage detector with high accuracy detection, manufactured using CMOS
process and laser trimming technologies.
Since the sense pin is separated from the power supply pin, it allows the IC to monitor the other power supply.
The XC6118 can maintain the state of detection even when voltage of the monitored power supply drops to 0V.
Moreover, a release delay time can be adjusted by the external capacitor connected to the Cd pin.
The VOUT pin is available in both CMOS and N-channel open drain output configurations.

* In the XC6118xxxA/B series, the dissipation pad
should not be short-circuited with other pins.
* In the XC6118xxxC/D series, when the dissipation
pad is short-circuited with other pins, connect it to
the NC pin (No.2) pin before use.

Figre 2: Te mig chart of Fiure 1
①
②
③
As an early state, the sense pin is applied sufficiently high voltage (6.0V MAX.) and the delay capacitance (Cd) is charged
to the power supply input voltage, (VIN: 1.0V MIN., 6.0V MAX.). While the sense pin voltage (VSEN) starts dropping to
reach the detect voltage (VDF) (VSEN>VDF), the output voltage (VOUT) keeps the “High” level (=VIN).
* If a pull-up resistor of the XC6118N series (N-ch open drain) is connected to added power supply different from the input
voltage pin, the “High” level will be a voltage value where the pull-up resistor is connected.
When the sense pin voltage keeps dropping and becomes equal to the detect voltage (VSEN =VDF), an N-ch transistor (M1)
for the delay capacitance (Cd) discharge is turned ON, and starts to discharge the delay capacitance (Cd). An inverter
(Inv.1) operates as a comparator of the reference voltage VIN, and the output voltage changes into the “Low” level (=VSS).
The detect delay time [tDF] is defined as time which ranges from VSEN=VDF to the VOUT of “Low” level (especially, when the
Cd pin is not connected: tDF0).
While the sense pin voltage keeps below the detect voltage, the delay capacitance (Cd) is discharged to the ground voltage
(=VSS) level. Then, the output voltage maintains the “Low” level while the sense pin voltage increases again to reach the
release voltage (VSEN< VDF +VHYS).
11/20
XC6118 Series
■OPERATIONAL EXPLANATION (Continued)
④
When the sense pin voltage continues to increase up to the release voltage level (VDF+VHYS), the N-ch transistor (M1) for
the delay capacitance (Cd) discharge will be turned OFF, and the delay capacitance (Cd) will start discharging via a delay
resistor (RDELAY). The inverter (Inv.1) will operate as a comparator (Rise Logic Threshold: VTLH=VTCD, Fall Logic
Threshold: VTHL=VSS) while the sense pin voltage keeps higher than the detect voltage (VSEN > VDF).
⑤
While the delay capacitance pin voltage (VCD) rises to reach the delay capacitance pin threshold voltage (VTCD) with the
sense pin voltage equal to the release voltage or higher, the sense pin will be charged by the time constant of the RC series
circuit. Assuming the time to the release delay time (tDR), it can be given by the formula (1).
tDR=-RDELAY×Cd×ln(1-VTCD/VIN) …(1)
The release delay time can also be briefly calculated with the formula (2) because the delay resistance is 2.0MΩ(TYP.) and
the delay capacitance pin threshold voltage is VIN /2 (TYP.)
tDR=RDELAY×Cd×0.69 …(2)
*：RDELAY is 2.0MΩ（TYP.）
As an example, presuming that the delay capacitance is 0.68μF, tDR is :
2.0×106×0.68×10-6×0.69=938(ms)
* Note that the release delay time may remarkably be short when the delay capacitance (Cd) is not discharged to the ground
(=VSS) level because time described in ③ is short.
⑥
⑦
When the delay capacitance pin voltage reaches to the delay capacitance pin threshold voltage (VCD=VTCD), the inverter
(Inv.1) will be inverted. As a result, the output voltage changes into the “High” (=VIN) level. tDR0 is defined as time which
ranges from VSEN=VDF+VHYS to the VOUT of “High” level without connecting to the Cd.
While the sense voltage is higher than the detect voltage (VSEN > VDF), the delay capacitance pin is charged until the delay
capacitance pin voltage becomes the input voltage level. Therefore, the output voltage maintains the “High”(=VIN) level.

■NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising
phenomenon, the IC is liable to malfunction should the ratings be exceeded.
2. The power supply input pin voltage drops by the resistance between power supply and the VIN pin, and by through current at
operation of the IC. At this time, the operation may be wrong if the power supply input pin voltage falls below the minimum
operating voltage range. In CMOS output, for output current, drops in the power supply input pin voltage similarly occur.
Moreover, in CMOS output, when the VIN pin and the sense pin are short-circuited and used, oscillation of the circuit may
occur if the drops in voltage, which caused by through current at operation of the IC, exceed the hysteresis voltage. Note it
especially when you use the IC with the VIN pin connected to a resistor.
3. When the setting voltage is less than 1.0V, be sure to separate the VIN pin and the sense pin, and to apply the voltage over
1.0V to the VIN pin.
4. Note that a rapid and high fluctuation of the power supply input pin voltage may cause a wrong operation.
5. Power supply noise may cause operational function errors, Care must be taken to put the capacitor between VIN-GND and
test on the board carefully.
6. When there is a possibility of which the power supply input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release operation
with the delay capacitance pin (Cd) connected to a capacitor, use a Schottky barrier diode connected between the VIN pin
and the Cd pin as the Figure 3 shown below.
7. In N channel open drain output, VOUT voltage at detect and release is determined by resistance of a pull up resistor
connected at the VOUT pin. Please choose proper resistance values with refer to Figure 4;
During detection: VOUT = VPULL / (1+RPULL / RON
PULL: Pull up voltage
ON(※1)：On resistance of N channel driver M3 can be calculated as VDS / IOUT1 from electrical characteristics,
For example, when (※2) RON = 0.5 / 0.8×10-3 = 625Ω（MAX.）at VIN=2.0V, VPULL = 3.0V and VOUT ≦0.1V at detect,
PULL= (VPULL /VOUT-1)×RON= (3 / 0.1-1)×625≒18ｋΩ
)
V
R
R
In this case, RPULL should be selected higher or equal to 18kΩ in order to keep the output voltage less than 0.1V during
detection.
(※1) RON is bigger when VIN is smaller, be noted.
(※2) For calculation, Minimum VIN should be chosen among the input voltage range.
During releasing：VOUT = VPULL / (1 + RPULL / ROFF
)
VPULL：Pull up voltage
ROFF：On resistance of N channel driver M3 is 15MΩ（MIN.） when the driver is off (as to VOUT / ILEAK
For example：when VPULL = 6.0V and VOUT ≧ 5.99V,
)
R
PULL = (VPULL / VOUT-1)×ROFF = (6/5.99-1)×15×106 ≒25 kΩ
In this case, RPULL should be selected smaller or equal to 25 kΩ in order to obtain output voltage higher than 5.99V during
releasing.
