MAX690SESA

Supervisors Overview

The MAX690SESA is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.65 V with an overvoltage threshold of 4.75 V. The device provides active low, push-pull output and includes a watchdog timer and battery backup switch functionality. It has a reset delay time of 70 ms and draws 10 mA of operating current. The component is housed in an SOIC-8 package and supports surface mount installation. It functions without manual reset or chip enable signals.

Supervisors Feature Summary

• Integrates power supply monitoring with watchdog timing and battery backup switching for comprehensive system supervision.
• Provides active low push-pull reset output to ensure reliable microprocessor initialization during power events.
• Includes dedicated power failure detection capabilities to alert systems of voltage anomalies.

Supervisors Applications

• Microprocessor system reset circuits
• Battery backup management systems
• CMOS RAM write protection applications

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special order conditions. Confirm RoHS compliance details through official documentation before procurement. Ensure the specific suffix matches required packaging options such as reel or cut tape. Check for any regional sales restrictions that may affect acquisition channels.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for standard logic families. Consider the 10 mA operating current against lower-power alternatives if energy efficiency is critical. Verify that the SOIC-8 package fits the board layout constraints. Ensure the absence of manual reset input aligns with the design requirements.

Supervisors Part Context

This part belongs to the MAX690S series of supervisory circuits designed for microprocessor applications. It shares functional similarities with other parts in the family but is distinguished by its specific threshold voltages and package type. The series focuses on providing complete power supply monitoring and battery control functions for embedded systems.
