MAX698EWE+

Supervisors Overview

The MAX698EWE+ is a supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated), housed in a 16-SOIC package. It monitors a single voltage input with a threshold range of 3.3 V to 5.5 V and supports active high, active low, open drain, and push-pull outputs. The device features a watchdog timer, lacks manual reset or battery backup switches, and has a reset delay time of 500 ms. Operating at a maximum supply voltage of 5.5 V, it functions within a temperature range of -40°C to +85°C with an accuracy of 2.5% and a typical operating current of 5 mA.

Supervisors Feature Summary

• Integrates power-on reset functionality with a built-in watchdog timer for system reliability.
• Provides flexible output configurations including active high, active low, open drain, and push-pull modes.
• Supports wide input voltage thresholds ranging from 3.3 V to 5.5 V for versatile monitoring applications.

Supervisors Applications

• Microprocessor power supply monitoring
• Watchdog timer implementation in embedded systems
• Power-on reset generation for digital circuits

Supervisors Procurement Notes

Verify the specific suffix 'EWE+' against the official Maxim Integrated datasheet to confirm the SOIC-Wide-16 package and industrial temperature grade (-40°C to +85°C). Ensure the required output configuration matches the available options: active high, active low, open drain, or push-pull. Confirm that the application does not require manual reset or battery backup switching, as these features are absent in this part number.

Supervisors Selection Notes

Select the MAX698EWE+ when a combined power-on reset and watchdog timer solution is required for a single voltage rail. This component is suitable for designs needing flexible output drive types without manual intervention capabilities. Consider the 5 mA operating current and 500 ms reset delay during timing analysis. Verify that the monitored voltage falls within the 3.3 V to 5.5 V threshold range for proper supervision.

Supervisors Part Context

The MAX698 belongs to the Maxim Integrated supervisory circuit family, designed for cost-effective system protection. It serves as a fundamental component for ensuring microprocessor stability by detecting power anomalies and managing system resets through integrated watchdog mechanisms.
