The XC6119 series is a highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming
technologies.
The device includes the built-in delay circuit. A release delay time can be set freely by connecting an external delay capacitor to
the Cd pin.
The device using an ultra small package (USPN-4) is suited for high density mounting applications.
Both CMOS and N-channel open drain output configurations are available.

① As an early state, the input voltage pin is a pplied sufficiently high voltage to the releas e voltage and the delay capacitance

IN
② When the input pin voltage keeps dropping and becomes equal to the detect voltage (V
= VDF), an N-ch transistor for the
IN
delay capacitance discharge is turned ON, and starts to discharge the delay capacitance. For the internal circuit, which
uses the delay capacitance pin as power input, the reference voltage operates as a comparator of VIN, and the output
voltage changes into the “Low” level (≦V

of “Low” level (especially, when the Cd pin is not connected: t

③ While the input pin voltage keeps below the detect voltage, and 0.7V or more, the delay capacitance is discharged to the
ground voltage (=V
) level. Then, the output voltage (V
SS
) maintains the “Low” level.
OUT
④ While the input pin voltage drops to less than 0.7V and it increases again to 0.7V or more, the output voltage may not be able
to maintain the “Low” level. Such an operation is called “Unspecified Operation”, and voltage which occurs at the output pin
voltage is defined as unstable operating voltage (V

■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 input pin voltage drops by the resistance between power supply and the V
the IC. At this time, the operation may be wrong if the input pin voltage falls below the minimum operati ng voltage range.
In CMOS output, for output current, drops in the input pin voltage similarly occur. 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 V
3. Note that a rapid and high fluctuation of the input pin voltage may cause a wrong operation.
4. Power supply noise may cause an operational function error. Care must be taken to put an external capacitor between
-GND and test on the board carefully.
V
IN
5. When there is a possibility of which the input pin voltage fall s 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 V
as the Figure 3 shown below.
6. When N-channel o pen drain output is used, output voltages V
pull-up resistor tied to the output pin. A resistance value of the pull-up resistor can be selected with referring to the
followings. (Refer to Figure 4)
