XC6118
Series
Voltage Detector with Separated Sense Pin & Delay Capacitor Pin
ETR02013-005
■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 V
OUT
pin is available in both CMOS and N-channel open drain output configurations.
■APPLICATIONS

* 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.
