The MAX6730UTSD2+T from Maxim Integrated is a highly reliable, single/dual low-voltage microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a single 2.5V to 5.5V supply.

This component ensures that the µP and its peripherals are reset properly during a power-up, power-down, or brown-out condition. Its key features include a factory-trimmed reset threshold voltage, a 140ms min reset active time, and a low supply current of only 5.5µA (typical), which makes it ideal for power-conscious applications. The MAX6730UTSD2+T operates over an extended temperature range of -40°C to +85°C, catering to industrial requirements.
