Additional Details

The S-80920ALMP-DAH-T2 features a detection voltage of 2.0V and an operating voltage range of 0.8V to 10V. It consumes very little current, making it suitable for use in battery-powered devices where energy conservation is critical. The built-in hysteresis helps to prevent oscillations in the output signal when the input voltage is near the detection threshold, ensuring a stable and reliable reset signal. The N-channel open drain output requires an external pull-up resistor. The device is available in a small SOT-23-3 package, which allows for easy integration into compact electronic designs. The DAH suffix likely refers to specific tape and reel packaging details or internal production codes. The T2 indicates tape and reel packaging.
