The MAX6346UR40+T from Maxim Integrated is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 4.0V power supply voltage.

Key Features

• Precision Monitoring: This device features a precision factory-set V_CC reset threshold at 4.0V, ensuring accurate monitoring of the system voltage.
• Low Power Consumption: With its low supply current of 5.5µA (typical), it is ideal for battery-operated equipment, contributing to extended battery life.
• Manual Reset Input: The manual reset input allows for a system reset to be asserted at any time by the user or another system component, adding an additional layer of system control.
• Reset Timeout: The device offers a 140ms (min) reset timeout period, providing a reliable reset signal for proper system restart and initialization.
• Immune to Short V_CC Transients: The MAX6346UR40+T is designed to ignore short-duration transients on the V_CC line, which prevents false triggering of the reset signal.

Applications

With its robust feature set, the MAX6346UR40+T is suitable for a variety of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
