Maxim Integrated MAX6717UKSDD3+ Triple/Quad Voltage μP Supervisory Circuits

The MAX6717UKSDD3+ is a high-quality microprocessor (μP) supervisory circuit developed by Maxim Integrated, designed to monitor triple or quad voltage levels. This component is vital for systems that require precise voltage regulation and monitoring to ensure reliable operation. Its compact SOT23 package makes it an ideal choice for space-constrained applications.

Key features of the MAX6717UKSDD3+ include the ability to monitor three or four system power-supply voltages simultaneously. This is crucial for systems that operate with different voltage rails and need to maintain proper functionality even under varying power conditions. The device asserts a reset signal if any of the monitored voltages fall below their factory-programmed thresholds, ensuring the system responds appropriately to power anomalies.

The reset output from the MAX6717UKSDD3+ is available in either an active-low push-pull or an active-low open-drain configuration. This flexibility allows designers to choose the appropriate reset signal type based on the specific requirements of their system. The reset signal is guaranteed to remain asserted for a minimum of 140ms after all voltages have returned to acceptable levels, providing a reliable reset duration for proper system recovery.

Another significant advantage of the MAX6717UKSDD3+ is its low supply current, which is particularly beneficial for battery-powered devices where power conservation is critical. The device operates over a wide voltage range and has a low quiescent current, making it suitable for various applications, including portable devices, computers, controllers, and intelligent instruments.

Furthermore, this supervisory circuit offers an adjustable reset threshold and hysteresis, which allows for fine-tuning the voltage monitoring according to specific system requirements. The MAX6717UKSDD3+ also features a manual reset input, providing an additional layer of system control, enabling users to trigger a reset manually when necessary.

In summary, the Maxim Integrated MAX6717UKSDD3+ is a versatile and reliable solution for systems requiring multiple voltage monitoring and precise control over their power supply conditions. Its small form factor, low power consumption, and customizable features make it an excellent choice for a wide range of applications.
