Maxim Integrated MAX6717UKSDD3+T - Dual/Triple-Voltage µP Supervisory Circuits

The Maxim Integrated MAX6717UKSDD3+T is a highly reliable dual/triple-voltage microprocessor (µP) supervisory circuit designed to maintain system integrity by monitoring power supply voltages in digital systems. It is perfect for applications that require precise voltage monitoring to safeguard critical data and ensure proper system functionality during power-up, power-down, and brown-out conditions. With its compact SOT23-5 package, this device is ideal for space-constrained applications in various electronic devices.

This supervisory circuit monitors two or three system power-supply voltages simultaneously, making it versatile for different configurations. The MAX6717UKSDD3+T asserts a reset signal whenever any of the monitored voltages fall below their factory-set thresholds, ensuring that the µP and other critical components start in a known state. The reset signal remains asserted for a minimum timeout period after all voltages rise above their respective thresholds, providing a stable system reset.

Key features of the MAX6717UKSDD3+T include:

• Factory-set reset threshold voltages for precise monitoring.
• Low supply current, making it suitable for power-sensitive applications.
• Manual reset input for added system flexibility and control.
• Independent watchdog timer to monitor system operation.
• Immune to short VCC transients, enhancing system reliability.

The device operates over a wide voltage range, catering to various power requirements, and is characterized for operation over the full industrial temperature range. Its robust design includes features such as overtemperature protection and a wide operating temperature range, making it suitable for harsh environments.

Applications for the MAX6717UKSDD3+T are diverse and include portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP and µC power monitoring. Its small size and powerful features make it an excellent choice for designers looking to enhance the reliability and performance of their systems.

By integrating the MAX6717UKSDD3+T into your design, you can ensure that your system is protected from the dangers of undervoltage conditions, providing peace of mind and a higher level of product reliability.
