MAX6303ESA+

Supervisors Overview

The MAX6303ESA+ is a supervisory circuit designed for +5V systems, featuring low-power operation and adjustable reset thresholds. It integrates a watchdog timer and manual reset functionality within an SOIC-8 surface-mount package. The device monitors a single input voltage with an active-low push-pull output. It operates within a supply voltage range of 1.2V to 5.5V and supports a reset delay time of 5.2 ms. The component functions across commercial temperatures from 0°C to +70°C.

Supervisors Feature Summary

• Integrates adjustable power-supply monitoring with manual reset capability
• Includes built-in watchdog timer for system reliability
• Provides active-low push-pull output for direct logic interfacing

Supervisors Applications

• Critical microprocessor monitoring in embedded controllers
• Battery-powered computers and intelligent instruments
• Safety-critical automotive applications requiring robust supervision

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current manufacturer datasheets. Check for obsolescence or lifecycle changes directly with authorized distributors. Ensure the ordering part number matches the required temperature grade and packaging format for your production needs.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with integrated watchdog functionality is required. It is suitable for designs needing adjustable reset thresholds and manual reset inputs. Consider the SOIC-8 package constraints and the 0°C to +70°C operating temperature range during thermal design. Verify that the 4µA quiescent current meets the low-power requirements of the target application.

Supervisors Part Context

The MAX6303 belongs to the Maxim Integrated line of low-power supervisory circuits. It is part of a family designed for monitoring voltage levels in portable and industrial electronics. The device complements other reset controllers by offering combined watchdog and power-on reset features in a compact footprint.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully before replacing.
