Delay capacitor adjustable voltage detectors with sense pin isolation
New Product Leaflet
XC6132/XC6133/XC6134 Series
The XC6132/XC6133/XC6134 series are voltage detectors of the sense pin isolation type with capacitor-
delay function. The sense pin and power input pin are isolated to enable monitoring of the voltage of another
power supply. The output can be maintained in the detect state even if the power voltage drops to 0V. The
sense pin is also suitable for detecting high voltage, and the detection and release voltage can be set to any
value using an external resistance.
The XC6132/XC6134 series has a HYS external adjustment pin that allows the hysteresis to be set as
desired using a single resistor. These voltage detectors are ideal for monitoring the voltage of a vehicle
battery during cranking, and for power supplies with large voltage fluctuations such as an electric double
layer.The XC6132 series also has an internal surge voltage protection circuit. This protects the IC even
when overvoltage is applied to the input.

Set any hysteresis with a single resistor
Any hysteresis can be set by connecting a resistor
(R3) between the VSEN and HYS pins.
Any release and detection delay time can be set with an external
capacitor Accuracy and temperature characteristics are even
better than previous products

RESETB
The detection voltage and release voltage can be
adjusted to any value by resistance dividing. Furthermore, the hysteresis voltage can be adjusted with a
single resistor, enabling control by means of a simple
circuit that does not cause false detection even when
the voltage drops significantly during cranking.
L level (RESETB) at detection or H level (RESET) at
detection can be selected, allowing you to choose the
output type that suits your specifications.
