The MAX6419UK29 is a compact, high-precision microprocessor (μP) supervisory circuit designed by Maxim Integrated 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 2.9V power supply voltage.

Key Features

• Voltage Monitoring: This device ensures that the system microprocessor is reset to a known state during power-up, power-down, and brownout conditions by precisely monitoring the 2.9V power supply voltage.
• Compact Design: Housed in an ultra-small SOT23 package, the MAX6419UK29 is ideal for space-constrained applications.
• Low Power Consumption: It features a low quiescent current of only 1.2µA, making it suitable for battery-operated and portable devices.
• Manual Reset: An active-low manual reset input allows for a manual system reset, providing additional system control.
• Reset Timeout: The device offers an internally fixed reset timeout period, ensuring that the system microprocessor is held in the reset state for a sufficient amount of time to allow for proper stabilization.
