MAX800MCSE+

Supervisors Overview

The MAX800MCSE+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin SOIC package. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.4 V with an overvoltage threshold of 4.45 V. The device includes a watchdog timer, battery backup switch, and chip enable signal, while lacking manual reset functionality. It provides active high, active low, and open drain outputs with a reset delay time of 200 ms. Operating currents are specified at 100 uA, and the unit supports power failure detection across a temperature range of 0 C to +70 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside a battery backup switch capability.
• Offers flexible output configurations including active high, active low, and open drain options.
• Includes a chip enable signal for controlled operation without manual reset inputs.

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded systems
• Power management IC applications

Supervisors Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete or limited supply. Confirm RoHS compliance details and check regional sales restrictions before ordering. Ensure the specific suffix matches required package and electrical specifications. Cross-reference datasheet revisions to confirm current manufacturing status and availability constraints.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated watchdog protection is required. Consider the 16-pin SOIC package for surface mount applications. Evaluate the 4.4 V threshold against system rail requirements. Verify that the absence of manual reset aligns with design needs. Check operating current consumption against power budget constraints.

Supervisors Part Context

This part belongs to the MAX800M series of supervisory circuits designed for microprocessor applications. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its specific package type and electrical parameters. The series typically offers reliable voltage monitoring with additional features like watchdog timers.
