Maxim Integrated MAX6719UTSVD3+T Microprocessor Supervisory Circuits

The MAX6719UTSVD3+T is a highly reliable and versatile microprocessor (µP) supervisory circuit, designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This supervisory circuit is engineered to monitor power supplies in µP and digital systems, ensuring proper system operation through monitoring of voltage levels.

This compact device is available in a space-saving, 6-pin SOT23 package, making it an ideal solution for applications where board space is at a premium. Its low supply current of 9µA (typical) makes it suitable for use in portable equipment and other power-sensitive applications.

The MAX6719UTSVD3+T offers a variety of features that enhance system reliability, including:

• Adjustable Reset Threshold: The reset threshold voltage can be externally adjusted, allowing for flexibility in different system designs and the ability to adapt to various processor requirements.
• Manual Reset Input: A manual reset input provides a means to trigger a system reset externally, which can be useful for system maintenance or in response to an unforeseen event.
• Power-On Reset Delay: The device includes a 140ms (min) power-on reset delay, which ensures that the system's microprocessor is held in reset for a sufficient time after power-up, allowing the power supply to stabilize before the processor starts.
• Low Power Consumption: With its low supply current, the device helps to minimize power usage, which is critical for battery-operated devices.
• High Accuracy Monitoring: The device maintains reset output until VCC reaches the reset threshold voltage, and it remains asserted for the reset timeout period after VCC rises above the reset threshold, ensuring stable system operation.

The MAX6719UTSVD3+T operates over a wide voltage range from 1.6V to 5.5V, catering to a broad spectrum of applications, from low-voltage portable devices to higher voltage digital systems. Its operating temperature range of -40°C to +125°C ensures reliable performance across diverse environmental conditions.

With its robust feature set, the MAX6719UTSVD3+T is an excellent choice for designers looking to incorporate an efficient and reliable supervisory circuit into their system designs, particularly in the areas of consumer electronics, telecommunications, and industrial control systems.
