Maxim Integrated MAX6717AUKTGD3+T Microprocessor Supervisory Circuit

The MAX6717AUKTGD3+T is a compact, high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. This device ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6717AUKTGD3+T is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and portable/battery-powered equipment.

This supervisory circuit provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 3.3V power supply. The MAX6717AUKTGD3+T features a manual reset input, which provides a robust level of system control as it allows the system to be reset from an external switch or a microcontroller (µC) pin. Additionally, the device has an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring the system microprocessor starts up correctly every time.

The MAX6717AUKTGD3+T comes in a tiny SOT23-5 package, making it highly suitable for space-constrained applications. Its low supply current of 9µA (typical) is particularly attractive for portable and battery-powered applications, where power conservation is crucial. The device operates over a wide temperature range of -40°C to +85°C, catering to industrial and commercial environments.

Key features of the MAX6717AUKTGD3+T include:

• Factory-trimmed VCC reset threshold voltages (2.63V, 2.93V)
• Manual reset input
• 140ms (min) reset timeout period
• Low supply current of 9µA (typical)
• Wide operating temperature range (-40°C to +85°C)
• Compact SOT23-5 packaging

With its precision monitoring capabilities and compact form factor, the Maxim Integrated MAX6717AUKTGD3+T is a reliable solution for ensuring system stability and integrity across various electronic applications.
