MAX6303CSA

Supervisors Overview

The MAX6303CSA+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features an adjustable overvoltage threshold. The device provides a manual reset input, a watchdog timer function, and an active-low push-pull output. It includes a reset delay time of 5.2 ms and consumes only 4 uA of operating current. The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside voltage supervision capabilities.
• Features an adjustable overvoltage threshold to accommodate various power rail requirements.
• Includes a manual reset input pin for user-initiated system recovery actions.

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the exact suffix designation, as the source data primarily references the MAX6303CSA+T variant. Confirm RoHS compliance status and lead times with authorized distributors, noting that availability may be restricted or limited for this specific part number. Ensure the selected package matches the required PCB footprint specifications.

Supervisors Selection Notes

Select this component when a low quiescent current of 4 uA is critical for battery-operated or energy-efficient designs. The adjustable threshold allows flexibility for non-standard voltage rails. Consider the SOIC-8 package for surface-mount assembly needs. Verify that the 5.5 V maximum rating aligns with the target system's power supply characteristics.
