Product Overview: MAX6414UK29/V+T from Maxim Integrated

The MAX6414UK29/V+T is a high-quality microprocessor (μP) supervisory circuit produced by Maxim Integrated, designed to monitor power supplies in μP and digital systems. It provides a significant layer of protection by ensuring that the system's voltage levels remain within operational thresholds, thus safeguarding the system from unpredictable behavior that could arise from power supply fluctuations.

This particular model of the MAX6414 series comes in a compact SOT23 package, making it ideal for space-constrained applications. The device operates over a wide voltage range, with a factory preset reset threshold voltage of 2.93V, tailored to monitor 3.3V power supplies. The reset output of the MAX6414UK29/V+T is active low and is guaranteed to be in the correct state for VCC down to 1.0V, which is particularly useful for low-voltage operations.

The MAX6414UK29/V+T features an impressive low supply current of only 1.5μA, making it an energy-efficient choice for portable and battery-operated devices. The device's reset timeout period is 140ms, ensuring that the system has sufficient time to stabilize before the μP starts its operation. This timeout period helps prevent system errors during power-up, power-down, and brownout conditions.

Maxim Integrated has designed this supervisory circuit with a robust feature set, including a manual reset input which allows for a system reset to be triggered with an external signal. This is an invaluable feature for systems that require user-initiated resets or for implementing a remote reset capability.

In summary, the MAX6414UK29/V+T is a reliable and efficient solution for system monitoring, providing essential protection against power supply anomalies. Its small footprint, low power consumption, and precise voltage monitoring capabilities make it a valuable component for maintaining the integrity of microprocessor-based systems.
