XC6132 Series
ETR02032-001
Delay capacitor adjustable voltage detectors with sense pin isolation,
surge voltage protection and HYS external adjustment
■GENERAL
DESCRIPTION
The XC6132 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 surge voltage protection circuit and an internal delay circuit are 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.
