Maxim Integrated MAX6305UK00D1+T Microprocessor Reset Circuit

The MAX6305UK00D1+T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. Manufactured by Maxim Integrated, a company renowned for its high-quality integrated circuits, this component provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

This supervisory circuit is specifically engineered to keep a system's microprocessor running smoothly by resetting it during power-up, power-down, and brown-out conditions. The MAX6305UK00D1+T ensures that the µP starts up in a known state every time the system is powered on and helps in preventing code execution errors during low voltage conditions.

The device comes in a compact SOT-23 package, making it suitable for space-constrained applications. It operates over a wide voltage range and features a factory-trimmed reset threshold voltage, which is preset to 3V, suitable for operation with a variety of supply voltages. The reset output is guaranteed to be in the correct state for V_CC down to 1V, making it reliable for low voltage operations.

Key features of the MAX6305UK00D1+T include:

• Factory-trimmed V_CC reset threshold voltage for high accuracy
• Immune to short V_CC transients
• Low power consumption with only 20µA supply current
• 150ms min power-on reset pulse width to ensure reliable startup
• Active-low, push-pull reset output which directly interfaces with microprocessors

Its applications are diverse, ranging from embedded systems, computers, controllers, intelligent instruments, to portable/battery-powered equipment. By providing a precise monitoring solution for V_CC, the MAX6305UK00D1+T from Maxim Integrated is an essential component for system reliability and robustness, ensuring that devices operate correctly and safely under varying power conditions.

In summary, the MAX6305UK00D1+T is a vital component for any system requiring a reliable reset mechanism for their microprocessors, ensuring that devices start correctly and operate as intended, regardless of the instability of the power supply.
