HX7030A is a SOT-89 RoHS-compliant microprocessor and microcontroller supervisor manufactured by Hengjiaxing. It provides low-power, low-voltage operation, with a wide operating voltage range of 1.8 V to 6.0 V. This component offers a high-performance, low-power reset solution for microcontroller and microprocessor applications. Its reset output is held down during reset, reducing power consumption and providing for a reliable reset in power-sensitive applications. The HX7030A features a watchdog timer for generating system resets, and also offers the option of an extended watchdog timeout. This device incorporates a manual reset button, designed for easy system debugging and home automation applications. In addition, it includes an active-high enable signal to prevent inadvertent reset and allow the system to enter sleep mode for power savings.
