Additional Details

The SG2007-1.8XN5/TR operates by continuously monitoring the input voltage. When the voltage drops below the 1.8V threshold, the open-drain output is asserted. This output requires an external pull-up resistor to define the logic high level. The built-in hysteresis prevents the output from oscillating when the input voltage is near the threshold, ensuring stable operation. The low quiescent current makes it suitable for battery-powered devices, minimizing battery drain. The device is designed to operate over a wide temperature range, making it suitable for various industrial and commercial applications. The small package size allows for easy integration into compact electronic designs. Its primary function is to safeguard electronic circuits from the harmful effects of undervoltage conditions by providing a reliable reset signal.
