MAX793RCSE+T

Supervisors Overview

The MAX793RCSE+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for microprocessor supervision. It operates within a supply voltage range up to 5.5 V and features an adjustable overvoltage threshold with fixed thresholds at 3.0 V and 3.3 V. The device includes a manual reset input, a watchdog timer, and a battery backup switch. It provides active high, active low, and open drain outputs with a reset delay time of 280 ms. The IC consumes 62 uA of quiescent current and functions in temperatures from -40 C to +85 C. It is housed in a SOIC-Narrow-16 package.

Supervisors Feature Summary

• Integrates manual reset functionality alongside automatic voltage monitoring for comprehensive system control.
• Includes a built-in watchdog timer and battery backup switch to ensure processor reliability during power anomalies.
• Offers configurable output states including active high, active low, and open drain configurations.

Supervisors Applications

• Microprocessor power supply supervision
• Battery backup switching systems
• Watchdog timer implementation in embedded controllers

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as distribution listings may vary. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the SOIC-Narrow-16 package matches your PCB footprint requirements. Check for obsolescence notices or limited availability statuses before finalizing procurement plans.

Supervisors Selection Notes

Select this component when adjustable overvoltage detection is required alongside standard 3.0 V and 3.3 V supervision. The 62 uA quiescent current makes it suitable for power-sensitive applications. Verify that the 280 ms reset delay meets your system startup timing constraints. Ensure the operating temperature range of -40 C to +85 C aligns with your environmental specifications.
