XC6134 Series
ETR02029-001
Delay capacitor adjustable voltage detectors with sense pin isolation and HYS
external adjustment
■GENERAL
DESCRIPTION
The XC6134 series are ultra-small delay capacitor adjustable type voltage detectors that have high accuracy and sense pin
isolation. High accuracy and a low supply current are achieved by means of a CMOS process, a highly accurate reference
power supply, and laser trimming technology.
The sense pin is isolated from the power input pin to enable monitoring of the voltage of another power supply. Output can be
maintained in the detection state even if the voltage of the power supply that is monitored drops to 0V. The sense pin is also
suitable for detecting high voltages, and the detection and release voltage can be set as desired using external resistors. An
internal delay circuit is also provided. By connecting a capacitor to the Cd/MRB pin, any release delay time and detect delay
time can be set, and the pin can also be used as a manual reset pin. The HYS external adjustment pin can be used to
establish a sufficient hysteresis width.
