Detailed Specs

The XC61GN1502HRN boasts a highly precise detection voltage, typically within ±1%. Its quiescent current consumption is extremely low, often in the microampere range, making it ideal for applications where power conservation is critical. The integrated hysteresis helps to avoid false reset signals caused by minor voltage fluctuations. It is typically packaged in a small SOT-25 package, which saves valuable PCB space. The device operates over a wide temperature range, usually from -40°C to +85°C. The open-drain output requires an external pull-up resistor. The device's primary function is to hold a reset signal low as long as the input voltage is below 1.5V. Once the input voltage exceeds 1.5V plus the hysteresis voltage, the reset signal will be released (pulled high by the external resistor).

This voltage detector is an essential component in many electronic systems, providing a crucial safety net against voltage drops that could lead to system instability or data corruption.
