Product Overview: MAX6804US29D3 from Maxim Integrated

The MAX6804US29D3 is a microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. This high-quality component provides excellent circuit reliability and low cost by eliminating the need for external components and adjustments when monitoring nominal system voltages of 2.93V.

Key Features

• Precision Voltage Monitoring: The device offers a precise factory-set V_CC reset threshold at 2.93V, ensuring accurate monitoring of the system voltage without the need for external resistors.
• Low Power Consumption: With a low supply current of only 1µA, the MAX6804US29D3 is optimized for power-sensitive applications, extending the life of battery-operated devices.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered with an external switch or logic signal.
• Reset Timeout: The device features an internally fixed reset timeout period of 140ms (min), which ensures a proper system reset without the need for external timing components.
• Immune to Short V_CC Transients: The MAX6804US29D3 is designed to ignore short transients on the V_CC line, providing stable operation during momentary voltage dips.
