HX7036

The HX70XX series is a three-pin low voltage detector implemented in CMOS technology. This series detects fixed voltages ranging from 2.2V to 7V. The detector consists of four functional blocks: a high-accuracy, low-power reference voltage source, a comparator, a hysteresis circuit, and an output driver. CMOS technology ensures low power consumption. Although the detector is primarily designed for fixed-voltage detection, user-defined threshold voltages can also be detected via external components (NMOS open-drain type only).
