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.
