Product Overview: MAX800MESE+T from Maxim Integrated

The MAX800MESE+T is a high-performance microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a single 5V power supply.

This supervisory circuit ensures that the µP is only operational when the power supply is within acceptable limits. It keeps the µP in reset mode during power-up, power-down, and brownout conditions. The reset signal remains asserted until the system voltage reaches the reset threshold level and maintains for a specified period, ensuring a proper system reset. The reset threshold voltage for the MAX800MESE+T is preset at the factory and is available in several options to accommodate different system requirements.

An additional feature of the MAX800MESE+T is the watchdog timer, which monitors the µP or microcontroller activity. If the µP does not provide a periodic signal to the watchdog input within a preset timeout period, the MAX800MESE+T will assert a system reset. This feature is crucial for systems that require high reliability and fail-safe operation.

The MAX800MESE+T comes in a 16-pin narrow SO package, making it suitable for space-constrained applications. It operates over a wide temperature range, making it versatile for use in various environments. The device also includes a manual reset input, allowing for an external trigger of the reset signal when needed.

With its combination of reset logic, watchdog capability, and manual reset input, the MAX800MESE+T is a robust solution for system management in complex digital systems such as computers, controllers, and intelligent instruments. Maxim Integrated's commitment to quality ensures that this supervisory circuit will enhance the reliability of any system it's integrated into.
