XC6118 Series
www.DataSheet4U.com
ETR0213-004
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.

NOTE:
*1: VDF (T): Nominal detect voltage
*2: Current to the sense resistor is not included.
*3: IOUT2 is applied only to the XC6118C series (CMOS output).
*4: It is calculated from the voltage value and the current value of the VSEN.
*5: It is calculated from the voltage value of the VIN and the current value of the Cd.
*6: Maximum VOUT voltage when VIN is changed from 0V to 1.0V under connecting the VIN pin to the VSEN pin.
This value is effective only to the XC6118C series (CMOS output).
*7: Delay time from the time of VSEN=VDF to the time of VOUT= 0.6V when the VSEN falls.
*8: Delay time from the time of VIN= VDF +VHYS to the time of VOUT = 5.4V when the VSEN rises.

Sense Pin Voltage: VSEN(MIN.:0V MAX.:6.0V)
Release Voltage: VDF+VHYS
Detect Voltage: VDF
Delay Capacitance Pin Voltage: VCD(MIN.:VSS, MAX.:VIN)
Delay Capacitance Pin Threshold Voltage: VTCD
Output Voltage Pin Voltage: VOUT (MIN.:VSS MAX:VIN)
Figure 2: The timing chart of Figure 1
① 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.
② 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).
③ 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).
