Maxim Integrated MAX6305EUK00D3 - Microprocessor Reset Circuit

The MAX6305EUK00D3 is a highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system integrity by ensuring that the µP and its associated circuitry reset cleanly during power-up, power-down, and brown-out conditions. This essential component is particularly well-suited for use in portable, battery-operated devices due to its low power consumption and compact SOT-23 packaging.

Key Features

• Precision Monitoring: The device features a precision factory-set V<sub>CC reset threshold voltage, ensuring reliable monitoring and system protection.
• Low Power Consumption: With its low 1.2µA supply current, the MAX6305EUK00D3 is designed for power-sensitive applications, extending battery life in portable devices.
• Manual Reset Input: It includes a manual reset input that allows for a system reset to be triggered with an external switch or logic signal.
• Debounced Reset Output: The reset output is debounced, eliminating any glitches during transition, and remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold level to ensure a proper system reset.
• Immunity to Short V<sub>CC Transients: The device is immune to short duration V<sub>CC transients, providing stable operation under noisy conditions.

Applications

The MAX6305EUK00D3 is versatile and can be used in a wide array of applications that require reliable system reset functionality. Common applications include:

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

This device from Maxim Integrated is a crucial component in ensuring the correct operation and longevity of digital systems. Its precise monitoring capabilities and low power consumption make the MAX6305EUK00D3 an excellent choice for designers looking to enhance system reliability and efficiency.
