The HX7039A with Microprocessor & Microcontroller Supervisors TO-92 RoHS is an integrated circuit (IC) manufactured by Hengjiaxing. Its purpose is to detect low voltage and take certain corrective measures, such as removing power from the device, restarting the device, etc. This IC is designed for use in applications with low voltage power supplies, such as automotive, industrial and consumer products. It offers three voltage monitor thresholds: low-voltage reset (LVRS), low-voltage detect (LVD) and reset input (RESIN). The LVRS and LVD thresholds are 1.2 V, and the RESIN is 2.25 V. It provides four-level protection against inappropriate operation due to abnormal power, and features current-limited reset sourcing. This IC is RoHS-compliant and comes in a TO-92 package.
