Maxim Integrated MAX6337US23D3 Microprocessor (μP) Supervisory Circuit

The Maxim Integrated MAX6337US23D3 is a highly reliable microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a significant level of system reliability and accuracy needed for controlling system reset and monitoring functions across various applications.

Key Features

• Precision Monitoring: This device features a precision factory-set V<sub>CC reset threshold at 2.3V, ensuring accurate monitoring of the power supply.
• Low Power Consumption: With its low supply current of only 5μA (typical), it is ideal for power-sensitive applications, extending the 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 button or logic signal.
• Reset Timeout: The MAX6337US23D3 offers a 140ms (min) reset timeout delay, providing a sufficient window to ensure system stability during power-up or when coming out of a reset state.
• Operating Temperature Range: It is designed to operate over the extended industrial temperature range of -40°C to +85°C, making it suitable for harsh environment applications.
• Compact Package: The device is available in a space-saving SOT-143 package, which is ideal for space-constrained applications.

Applications

Due to its robust feature set, the MAX6337US23D3 is well-suited for a wide range of applications, including:

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

Reliability and Safety

The device enhances system reliability by providing active-low RESET output guaranteed to be in the correct state for V<sub>CC down to 1V. This feature ensures that the μP resets properly during power-up, power-down, or brown-out conditions. The MAX6337US23D3's robust design and manufacturing under Maxim Integrated's stringent quality standards make it a trusted component for mission-critical applications.
