Technical Specifications

The RP102N251D-TR-F has a detection voltage of 2.5V. It boasts an ultra-low current consumption, typically in the microampere range, which is critical for battery-powered applications. The SOT-23 package allows for easy surface mounting and integration into compact electronic designs. The built-in hysteresis prevents unstable output signals during voltage transitions. The open-drain output provides flexibility in connecting to different logic levels and allows for wired-OR configurations. The device is designed to operate over a wide temperature range, ensuring reliability in various environmental conditions. The reset signal is asserted (low) when the input voltage drops below the detection threshold and de-asserted (high) when the input voltage rises above the threshold plus the hysteresis voltage.

The device's high accuracy and low power consumption make it an excellent choice for monitoring voltage levels in sensitive electronic circuits and ensuring proper system operation.
