MAX6326UR22 - Ultra-Low-Power SC70/SOT Microprocessor Reset Circuits

The MAX6326UR22 is a compact, highly-reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability through its ability to reset a µP during power-up, power-down, and brownout conditions, ensuring that the µP starts up in a known state.

This device is particularly well-suited for portable, battery-powered applications due to its ultra-low power consumption. The MAX6326UR22 operates with a nominal supply voltage of 2.2V, making it an ideal choice for systems that run on low voltage levels. Its low supply current of only 1µA (typical) further enhances its utility in power-sensitive designs.

The reset output of the MAX6326UR22 is guaranteed to be in the logic-low state down to V<sub>CC = 1.0V, which allows for a reliable reset operation even during low voltage conditions. The reset timeout period, which is the minimum interval for which the reset signal is maintained active, is factory-set to a standard value, eliminating the need for external timing components.

Housed in a small SC70 or SOT package, the MAX6326UR22 occupies minimal board space and is an excellent choice for space-constrained applications. The device's open-drain RESET output can sink up to 5.5V, allowing it to interface directly with both 3V and 5V logic.

Maxim Integrated ensures that the MAX6326UR22 meets stringent quality and performance standards. Its temperature range of -40°C to +85°C allows operation in diverse environmental conditions. The combination of low power consumption, small footprint, and high reliability make the MAX6326UR22 a preferred component for designers looking to enhance the stability of their digital systems.
