MAX693MLP

Supervisors Overview

The MAX693MLP is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4.5 V to 5.5 V and monitors a single input. Key electrical parameters include an undervoltage threshold of 4.25 V, an overvoltage threshold of 4.5 V, and a reset delay time of 50 ms. The device features active high, active low, and push-pull output types. It integrates a watchdog timer and battery backup switch functionality without manual reset capability. The component is housed in an LCC-20 package and supports chip enable signals.

Supervisors Feature Summary

• Integrates watchdog timer and battery backup switch for comprehensive power system management
• Provides configurable output states including active high, active low, and push-pull configurations
• Includes chip enable signal support for power optimization and control

Supervisors Applications

• Microprocessor power supply monitoring

Supervisors Procurement Notes

Verify the specific suffix /883B when sourcing, as it denotes military-grade qualification distinct from standard commercial variants. Confirm current availability status as the component may be discontinued or subject to limited supply constraints. Ensure compatibility with existing LCC-20 footprints during procurement planning.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision with integrated watchdog and backup functions. Consider the LCC-20 package size and operating temperature range of -55°C to +125°C for environmental suitability. Evaluate the need for specific output polarity options against system logic requirements.

Supervisors Part Context

The MAX693 belongs to the Maxim Integrated supervisory circuit family designed for reliable power management in digital systems. This series typically offers fixed thresholds for common voltage rails, simplifying design implementation. The MLP variant specifically utilizes the LCC-20 surface-mount package format.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and threshold compatibility if considering alternative supervisory circuits from other manufacturers.
