Maxim Integrated MAX6314US26D1+T Microprocessor Reset Circuit

The MAX6314US26D1+T is a high-quality microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides a significant level of system reliability through its precision monitoring of the power supply voltage, ensuring that the system microprocessor and other critical components operate within their specified voltage range.

This supervisory IC is tailored to maintain system integrity by generating a reset signal whenever the VCC supply voltage drops below the factory-set reset threshold level. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, providing a stable system reset to the microprocessor upon power-up, power-down, and brown-out conditions.

The MAX6314US26D1+T is characterized by its low supply current, making it an energy-efficient choice for battery-powered applications. Its reset threshold is set at 2.6V, which is suitable for 3V-powered systems. The device comes in a compact, 4-pin SOT-143 package, which is ideal for space-constrained applications.

Key features of the MAX6314US26D1+T include:

• Factory-set reset threshold voltage of 2.6V
• Low supply current of 1.2μA (typ) ideal for portable equipment
• Guaranteed reset valid to VCC = 1.0V
• ±2.5% Reset threshold accuracy over temperature
• Immune to short VCC transients
• 100ms (min) power-on reset pulse width
• Available in a small SOT143 package

Applications for the MAX6314US26D1+T are diverse and include portable/battery-powered equipment, computers, controllers, intelligent instruments, critical μP and μC power monitoring, and automotive systems where precise voltage monitoring is critical for reliable operation.

Maxim Integrated's commitment to quality ensures that the MAX6314US26D1+T supervisory circuit is a dependable component for maintaining system stability and integrity. By choosing this product, designers can enhance the operational safety and robustness of their electronic systems.
