MAX6303ESA+T

Supervisors Overview

The MAX6303ESA+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features an adjustable reset threshold voltage and includes a built-in watchdog timer with a manual reset input for enhanced system reliability. The device operates within a supply voltage range of 1V to 5.5V, consuming only 4µA of quiescent current. It provides an active-low push-pull output and offers a reset timeout of 5.2ms minimum. The component is housed in an 8-SOIC surface-mount package and supports operation across commercial temperature ranges.

Supervisors Feature Summary

• Integrates a watchdog timer with manual reset capability to prevent software lockups
• Features adjustable reset threshold voltage for flexible power monitoring applications
• Delivers active-low push-pull output signal for direct interface with logic circuits

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Watchdog timer implementation in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'ESA+T' against official Analog Devices documentation to confirm the SOIC-8 tape-and-reel packaging configuration. Ensure the part number matches the exact manufacturer designation, as suffixes define critical physical attributes. Cross-reference the datasheet revision history for any recent manufacturing changes or obsolescence notices prior to procurement planning.

Supervisors Selection Notes

Select this component when a low-quiescent current supervisory circuit with integrated watchdog functionality is required. The adjustable threshold allows customization for various supply rail voltages. Consider the 8-SOIC package constraints for PCB layout. Verify that the 5.2ms reset timeout meets the system's timing requirements compared to other fixed-timer alternatives.

Supervisors Part Context

This part belongs to the MAX6303 series of low-power supervisory circuits designed for microprocessor applications. The series typically combines voltage monitoring with watchdog timers to ensure system stability. The 'ESA' variant specifically denotes the surface-mount SOIC-8 package format, distinguishing it from through-hole DIP versions like the CPA.
