Delay capacitor adjustable voltage detectors with sense pin isolation
*AEC-Q100 (Grade1) compliant

The XD6133 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.

*TOREX’s automotive products (XD Series) are AEC-Q100 compliant.
