MAX702ESA+T

Supervisors Overview

The MAX702ESA+T is a power-supply monitor and reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.5 V to 15 V, featuring a threshold voltage of 4.65 V and an overvoltage threshold of 4.75 V. The device provides a manual reset input and delivers an active-low, push-pull output with a reset delay time of 350 ms. It consumes 200 uA of operating current and has a maximum power dissipation of 380 mW. The component is housed in an SOIC-8 package and supports surface-mount installation. It functions without a watchdog timer or battery backup switch, ensuring accurate voltage supervision with 2.5% accuracy across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise power-supply monitoring with dedicated reset signal generation for system protection.
• Features a manual reset input allowing external control over the reset state activation.
• Delivers an active-low, push-pull output compatible with standard digital logic interfaces.

Supervisors Applications

• Embedded systems requiring reliable power-fail detection and automatic microcontroller reset.
• Battery-powered devices needing voltage supervision to prevent erratic operation during low-power states.
• Industrial control circuits utilizing supervisory logic to maintain data integrity during power transitions.

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected supplier provides valid traceability for the Analog Devices/Maxim Integrated brand. Cross-reference the exact part number against current availability lists as distribution channels may vary.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for standard voltage rails. Consider the 350 ms reset delay duration relative to system startup requirements. Evaluate the 200 uA quiescent current against total power budget constraints. Verify that the SOIC-8 package dimensions fit the target PCB layout and thermal management strategy.

Supervisors Part Context

The MAX702ESA+T belongs to the MAX702 series of supervisory circuits designed for voltage monitoring applications. It serves as a critical interface between power sources and digital logic, ensuring stable operation by detecting under-voltage conditions.
