The Maxim Integrated MAX6420EUK29 is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a crucial function by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring proper operation of the µP during power-up, power-down, and brown-out conditions.

Key Features

• Precision Voltage Monitoring: The device features a factory-trimmed reset threshold voltage of 2.93V, suitable for 3V-powered systems, ensuring accurate monitoring of the power supply.
• Compact SOT23 Package: Housed in a tiny 5-pin SOT23 package, the MAX6420EUK29 is ideal for space-constrained applications.
• Low Power Consumption: With a low supply current of only 1.2µA, it is an excellent choice for battery-operated and portable devices, where power efficiency is crucial.
• Manual Reset Input: The inclusion of a manual reset input provides an additional layer of system control, allowing users to trigger a reset independently of the supply voltage.
• Reset Timeout: The device offers a fixed reset timeout period of 140ms (min), ensuring that the µP has sufficient time to initialize properly after a reset event.

Applications

The MAX6420EUK29 is versatile and can be used in a wide range of applications, including:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Data Storage Systems
• Industrial Controllers

Product Summary
