Maxim Integrated MAX6306EUK46D3+T Microprocessor Reset Circuit

The MAX6306EUK46D3+T is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. Manufactured by Maxim Integrated, this essential component is specifically engineered to monitor the power supply voltage in digital systems, providing a robust solution for managing system resets and power-on reset functionality.

This supervisory circuit comes in a compact SOT-23 package, making it suitable for space-constrained applications. Its precision voltage monitoring capability ensures that the connected microprocessor and other critical system components are protected from erratic behavior caused by unstable power conditions. The MAX6306EUK46D3+T features an active-low reset output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold level, providing ample time for the system to stabilize before the microprocessor starts its operation.

The device operates over a wide voltage range and offers a factory-trimmed reset threshold voltage of 4.63V, which is ideal for systems that require a higher level of voltage precision to maintain proper function. Moreover, the MAX6306EUK46D3+T supports a low supply current, making it an energy-efficient choice for battery-powered devices where power conservation is critical.

Key features of the MAX6306EUK46D3+T include:

• Factory-trimmed V_CC reset threshold voltage
• Minimum 140ms reset timeout period
• Low supply current for energy efficiency
• Wide operating voltage range
• Compact SOT-23 package suitable for space-constrained applications
• Immune to short V_CC transients

With its robust design and precise voltage monitoring, the MAX6306EUK46D3+T is a reliable and essential component for safeguarding microprocessor systems. Its integration into a system helps ensure a stable and reliable start-up and operation, even in the face of power supply irregularities, making it a preferred choice for designers looking to enhance system resilience and longevity.
