XC6138NASYMR-G

XC6138NASYMR-G is a XC6138 series multi-function, high accuracy voltage detector that can be detected high voltage with sense pin separation and external delay capacitor adjustable type. Since there is no need to divide the voltage by resistance as before, it contributes to higher accuracy of detect/release voltage and lower consumption current of the divider resistor. The delay time also can be adjusted externally with an external capacitor, and the ratio of detect/release time can be selected. The detect/release time can be set according to the application. The sense pin is separated from the power input pin, which can maintain the output in the detection state even if the monitoring voltage drops to 0V. Application includes battery voltage monitoring, system power-on reset, microcontroller reset and malfunction monitoring, power failure detection.
