MAX704CSA+

Supervisors Overview

The MAX704CSA+ is a low-cost 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 4.4 V with an overvoltage threshold of 4.5 V. The device provides a manual reset input, a battery backup switch, and power-fail detection capabilities. It utilizes an SOIC-8 surface-mount package and maintains a typical operating supply current of 350 uA. The reset delay time is specified at 200 ms, and the component supports an active low push-pull output configuration.

Supervisors Feature Summary

• Integrates manual reset functionality for user-initiated system control alongside automatic voltage supervision.
• Includes a dedicated battery backup switch pin to manage power transitions between primary and secondary sources.
• Provides power-fail detection to monitor supply voltage integrity and trigger appropriate system responses.

Supervisors Applications

• Microprocessor system monitoring
• Battery-powered equipment power management
• Portable electronic devices requiring voltage supervision

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited supply or discontinuation. Confirm RoHS compliance details through official documentation before integration. Ensure the specific suffix matches design requirements for package and temperature grade. Cross-reference datasheet specifications against application constraints to validate performance suitability.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with manual reset capability is required. The 4.4 V threshold suits standard 5 V logic systems. Consider the 350 uA quiescent current for power budget calculations. Verify that the SOIC-8 package fits the PCB layout constraints and thermal requirements of the target enclosure.

Supervisors Part Context
