MAX6303CSA+

Supervisors Overview

The MAX6303CSA+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single voltage inputs. It features an active low push-pull output and supports manual reset functionality with an integrated watchdog timer. The device operates within a supply voltage range of up to 5.5 V and consumes a typical operating current of 4 uA. It offers adjustable over-voltage thresholds and provides a reset delay time of 5.2 ms. The component is housed in an SOIC-8 surface-mount package and is rated for operation between 0°C and +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides adjustable over-voltage threshold detection capabilities
• Features low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor system supervision
• Battery backup switching circuits
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix and manufacturer documentation for the MAX6303CSA+ variant. Confirm RoHS compliance status and lead times through authorized distributors. Check for obsolescence notices or product change notifications from Analog Devices. Ensure the SOIC-8 package matches PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this component when adjustable over-voltage protection and watchdog functionality are required in a low-power environment. Compare against fixed-threshold supervisors if voltage precision is critical. Consider the SOIC-8 package size constraints relative to available board space. Evaluate the 4 uA quiescent current against total system power budgets.

Supervisors Part Context

This part belongs to the MAX6303 series of low-power microprocessor supervisory circuits. It complements other variants like the MAX6303CPA+ which offers a PDIP package option. The series focuses on providing essential reset and watchdog functions in compact packages for embedded systems requiring reliable voltage monitoring.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6303 family such as MAX6303CSA+T. Verify that any substitute maintains the same SOIC-8 package and electrical characteristics including the 5.2 ms reset delay and 4 uA current consumption.
