MAX807MCWE+

Supervisors Overview

The MAX807MCWE+ is a full-featured supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 4.575 V and an overvoltage threshold of 4.65 V. The device operates within a supply voltage range up to 5.5 V and features active high/low reset outputs with a minimum reset delay of 140 ms. It includes manual reset, watchdog timer, battery backup switch, and chip enable functions. Operating current is 70 uA, with power dissipation at 533 mW. It is housed in a 16-SOIC package and functions between 0°C and +70°C.

Supervisors Feature Summary

• Integrates manual reset, watchdog timer, battery backup switch, and chip enable for comprehensive system management
• Provides dual active high and active low reset output configurations
• Detects power failures and supports manual intervention via dedicated reset input

Supervisors Applications

• Portable equipment requiring low-power supervision
• Battery-powered systems needing backup switching
• Microprocessor-based designs requiring watchdog protection

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer declarations. Check availability as distribution may vary. Ensure the selected variant matches the required threshold voltage and operating conditions for the target application design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset capabilities is required. Verify that the 4.575 V threshold aligns with the monitored rail. Consider the 16-SOIC package constraints and the 0°C to +70°C industrial temperature range suitability for the intended environment.

Supervisors Part Context

This part belongs to the MAX807M series of supervisory circuits from Maxim Integrated. It is designed for applications requiring reliable power monitoring with minimal quiescent current. The series typically offers various threshold options and package styles to accommodate different system architectures and space requirements.

Supervisors Replacement Considerations

Consult official substitution guides for verified equivalents. Cross-reference pinouts and electrical parameters before implementation.
