MAX792MEPE+

Supervisors Overview

The MAX792MEPE+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides comprehensive power-supply and watchdog monitoring for systems without battery backup. The device features manual-reset input, independent watchdog timer, on-board gating of chip-enable signals, memory write-cycle completion, and voltage monitor for overvoltage warning. It operates within a supply voltage range of 3V to 5.5V and is available in a 16-pin SOIC package.

Supervisors Feature Summary

• Provides µP reset assertion during power-up, power-down, and brownout conditions with RESET valid down to 1V
• Includes manual-reset input and two-stage power-fail warning with separate low-line comparator
• Features independent watchdog timer with preset or adjustable timeout and pulsed watchdog output
• Offers memory write-cycle completion and on-board gating of chip-enable signals

Supervisors Applications

• Microprocessor system supervision
• Nonvolatile memory protection
• Power supply monitoring in embedded systems

Supervisors Procurement Notes

Verify the exact suffix against official documentation as legacy Maxim part numbering can vary. Confirm RoHS compliance status and lead times through authorized distributors. Check for obsolescence notices from Analog Devices. Ensure the package type matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when battery backup is not required but robust power monitoring is needed. Consider the MAX820 variant if higher threshold accuracy is specified in the datasheet. Evaluate the need for external programming of thresholds versus fixed internal options based on system design constraints.

Supervisors Part Context

The MAX792 series belongs to Maxim Integrated's line of microprocessor supervisory circuits designed for systems lacking battery backup. These devices integrate multiple functions typically requiring separate components, simplifying board design. The MAX792 specifically targets applications needing reliable reset generation and watchdog functionality.

Supervisors Replacement Considerations

The MAX820 is documented as functionally identical to the MAX792 except for guaranteed higher threshold accuracy in external programming mode. Verify pin compatibility and electrical specifications before substitution.
