Maxim Integrated MAX6354LSEUK Microprocessor Supervisory Circuit

The Maxim Integrated MAX6354LSEUK is a highly reliable microprocessor (µP) supervisory circuit designed 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 used with 5V-powered circuits.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6354LSEUK features a manual reset input that allows for a very low supply current of only 1.5µA, making it an ideal choice for portable and battery-powered applications where power conservation is crucial.

The reset output of the MAX6354LSEUK is guaranteed to be in the correct state for VCC down to 1V. It can significantly improve system reliability and accuracy compared to other solutions. The device comes in a compact and surface-mountable SOT-23 package, which is suitable for space-constrained applications.

Key features of the MAX6354LSEUK include:

• Precision monitoring of 5V power-supply voltages.
• Fully specified over temperature.
• Low power consumption with 1.5µA supply current.
• Manual reset input with a debounce feature.
• Reset output valid to VCC = 1V.
• Compact SOT-23 packaging.

Applications for the MAX6354LSEUK are diverse and include portable/battery-powered equipment, embedded systems, computers and controllers, automotive environments, and any system that requires a reliable reset signal to ensure proper operation after power disturbances.

Overall, the Maxim Integrated MAX6354LSEUK is a robust and efficient solution for maintaining system integrity through power fluctuations and manual reset events. Its integration into a system design can help to ensure that digital systems operate reliably without the need for external reset control components, saving on both space and cost.
