MAX6304ESA+T

Supervisors Overview

The MAX6304ESA+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features an adjustable overvoltage threshold ranging from 1.31 V to 5.5 V and a fixed 1.24 V undervoltage threshold. The device provides a 4 ms reset delay with an active-high, push-pull output. Operating on a single supply between 1.31 V and 5.5 V, it consumes only 4 uA of supply current. It includes a watchdog timer and is housed in an 8-pin NSOIC package, suitable for industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates adjustable overvoltage detection with a fixed undervoltage threshold for comprehensive power monitoring
• Includes a built-in watchdog timer to prevent software lockups in microprocessor systems
• Delivers an active-high, push-pull reset signal with a defined 4 ms delay time

Supervisors Applications

• Microprocessor power supervision
• Watchdog timer circuits
• Portable instrumentation power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer status as this component family may be subject to obsolescence notices. Ensure the adjustable threshold configuration matches the external resistor network requirements for the target application voltage.

Supervisors Selection Notes

Select this part when adjustable overvoltage protection is required alongside standard undervoltage supervision. The low quiescent current makes it suitable for battery-operated devices. Verify that the 4 ms delay meets the system's startup timing constraints. Ensure the SOIC-8 package fits the PCB layout constraints.

Supervisors Part Context

This component belongs to the MAX6304 series of low-power supervisors. It is functionally similar to the MAX6304EPA+ but utilizes surface-mount technology. The series is designed for applications requiring reliable power management with minimal standby current consumption.
