The MD7020 with SOT-23-3L is a RoHS compliant surface mount IC manufactured by Mingda. It is a highly versatile and compact device designed for monitoring and resetting circuits. It has three pins (S/R, IN, and GND) and the S/R pin can be programmed with a voltage range of 1.6 to 5.5V or set to open-drain reset. Additionally, it features a built-in hysteresis, adjustable timeout delay, and low-voltage reset, making it well-suited for a wide variety of applications. The MD7020 is also compatible with common logic families such as TTL, CMOS, and LVTTL.
