Maxim Integrated MAX6467US29D3 Voltage Supervisor

The MAX6467US29D3 is a precision, low-power voltage supervisor designed by Maxim Integrated to ensure reliable operation of microprocessors (µPs), microcontrollers (MCUs), and other digital systems. This compact and efficient component is a crucial part of any system that requires accurate monitoring of its power supply to safeguard against undervoltage conditions.

Featuring a fixed-sense threshold voltage of 2.93V, the MAX6467US29D3 provides a robust solution for 3.3V-powered systems. When the monitored voltage falls below the threshold, the device asserts a reset signal, which remains active until the voltage recovers and stabilizes above the threshold. This reset signal ensures that the connected digital system restarts in a known, safe state, preventing potential data corruption or erratic behavior.

The device comes in a compact SOT-143 package, making it suitable for space-constrained applications. Its low 1.2µA supply current makes it an excellent choice for battery-powered and portable devices where power efficiency is paramount.

Key features of the MAX6467US29D3 include:

• Fixed 2.93V threshold voltage for monitoring 3.3V power supplies
• Low 1.2µA supply current, ideal for power-sensitive applications
• Guaranteed reset valid to VCC = 1V for low-voltage operation
• 140ms (min) reset timeout period that provides system stability
• Immunity to short VCC transients to prevent false triggering
• Compact SOT-143 package suitable for space-saving designs

Applications that can benefit from the MAX6467US29D3 include:

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

The MAX6467US29D3 voltage supervisor by Maxim Integrated is a reliable and efficient solution for any application that requires precise voltage monitoring to protect the integrity and reliability of the system. With its low power consumption and compact size, it is an excellent choice for a wide range of applications across various industries.
