MAX709SCSA+T

Supervisors Overview

The MAX709SCSA+T is a power-supply monitor and reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low, push-pull output. The device provides a fixed threshold voltage of 2.93 V with 2.5% accuracy. It includes a reset delay time of 280 ms and consumes 65 uA of operating current. The component supports manual reset functionality and detects power failures. It is housed in an 8-SOIC package and functions within a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Provides automatic system reset upon detection of under-voltage conditions
• Includes manual reset input for user-initiated control
• Detects power failure events to support backup battery switching

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microprocessor-based designs needing reset generation
• Battery-powered equipment monitoring voltage levels

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging availability, as standard listings may indicate tube packaging. Confirm RoHS compliance status and lead-free specifications directly with the supplier or manufacturer datasheet before procurement. Ensure the ordering part number matches the required package type and electrical characteristics precisely.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is appropriate for the target logic family. Consider the 280 ms reset delay and 65 uA quiescent current for low-power applications. Verify that the SOIC-8 package fits the board layout constraints. Compare against other MAX709 variants if different thresholds or reset delays are required for the specific design.

Supervisors Part Context

This part belongs to the MAX709S series of supervisory circuits designed for monitoring single power supplies. It integrates voltage monitoring and reset generation in a compact surface-mount package. The series is intended for industrial and commercial applications where stable operation during power transitions is critical for system integrity.
