Maxim Integrated MAX6719UTZGD3+T Microprocessor Supervisory Circuits

The MAX6719UTZGD3+T from Maxim Integrated is a quintuple microprocessor (µP) supervisory circuit engineered to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 1.8V to 5V. This supervisory circuit is ideal for use in a wide range of applications including computers, controllers, portable/battery-powered equipment, and intelligent instruments.

One of the key features of the MAX6719UTZGD3+T is its ability to monitor up to five different voltages, making it incredibly versatile for complex systems that require multiple voltage checks. The device includes a manual reset input and an adjustable power-on reset (POR) timer, which gives designers the flexibility to set the reset assertion time according to their system requirements.

The MAX6719UTZGD3+T comes in a compact, 6-pin SOT23 package, suitable for space-constrained applications. Its small size, combined with its extended temperature range of -40°C to +125°C, makes it a robust choice for various environmental conditions.

Additional features of the MAX6719UTZGD3+T include:

• Low supply current of 7µA (typical), which is essential for power-sensitive applications.
• Factory-trimmed reset thresholds for accurate monitoring.
• Debounced manual reset input, allowing for a clean system reset without noise interference.
• Power-fail comparator for monitoring undervoltage conditions.
• Active-low reset output, which ensures compatibility with a variety of microprocessors and other digital systems.

The MAX6719UTZGD3+T is a tape-and-reel packaged product, indicated by the '+T' suffix, making it suitable for automated assembly processes and high-volume production. Maxim Integrated's commitment to quality and reliability is evident in this product, which is designed to improve system stability and reduce the risk of system failure due to improper voltage levels or processor malfunctions.

Overall, the Maxim Integrated MAX6719UTZGD3+T is a powerful solution for designers looking to enhance the safety and reliability of their digital systems through precise voltage monitoring and reset functions.
