XC6108
Series
Voltage Detector with Separated Sense Pin & Delay Capacitor Pin
ETR0205_008
■GENERAL
DESCRIPTION
The XC6108 series is highly precise, low power consumption voltage detector, manufactured using CMOS and laser trimming
technologies.
Since the sense pin is separated from power supply, it allows the IC to monitor added power supply.
Using the IC with the sense pin separated from power supply enables output to maintain the state of detection even when
voltage of the monitored power supply drops to 0V.
Moreover, with the built-in delay circuit, connecting the delay capacitance pin to the capacitor enables the IC to provide an
arbitrary release delay time.
Both CMOS and N-channel open drain output configurations are available.

* In the XC6108xxxA/B series, the dissipation pad should
not be short-circuited with other pins.
* In the XC6108xxxC/D series, when the dissipation pad
is short-circuited with other pins, connect it to the NC
pin (No.2) pin before use.
