Maxim Integrated MAX6355SYUT+T Voltage Supervisory IC

The MAX6355SYUT+T from Maxim Integrated is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered applications, portable equipment, computers, and controllers.

This supervisory IC ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6355SYUT+T has a factory-trimmed reset threshold voltage, making it suitable for monitoring 3V, 3.3V, and 5V powered circuits. It is available in a compact SOT-23 package, which is ideal for space-constrained applications.

Key features of the MAX6355SYUT+T include:

• Factory-Set Reset Thresholds: It comes with preset threshold voltages for different applications, ensuring compatibility with a variety of power supply voltages.
• Low Power Consumption: With a typical quiescent current of only 1.2µA, this device is optimal for battery-powered applications where power efficiency is critical.
• Manual Reset Input: The device includes a manual reset input that allows for a reset to be triggered with an external push-button or logic signal.
• Reset Output: The open-drain reset output ensures a well-defined reset signal to the µP.
• Immune to Short VCC Transients: The device is designed to ignore fast transients on the VCC line, which helps to prevent false triggering of the reset signal.
• Temperature Range: It operates over an extended temperature range, making it suitable for industrial applications.

The MAX6355SYUT+T supervisory circuit is designed to maintain system integrity and prevent erroneous operations. It is a critical component for ensuring the reliable operation of microprocessor-based systems, particularly in environments where power conditions are unpredictable or where a controlled system reset is necessary. Maxim Integrated's commitment to quality and reliability makes the MAX6355SYUT+T an excellent choice for your supervisory needs.

Whether you're designing complex digital systems or simple microcontroller boards, the MAX6355SYUT+T offers the precision and reliability that engineers expect from Maxim Integrated products.
