MAX6304CSA

Supervisors Overview

The MAX6304CSA+ is a low-power microprocessor supervisory circuit from the MAX6304 series, manufactured by Analog Devices (Maxim Integrated). It provides adjustable reset and watchdog timer functions to monitor system voltage. The device operates within a supply voltage range up to 5.5V and features an active-high, push-pull output. Key electrical parameters include a threshold voltage of 1.24V, a reset delay time of 4ms, and a typical supply current of 4µA. It offers 2% accuracy for the reset threshold and supports an adjustable overvoltage threshold. The component is housed in an SOIC-8 surface-mount package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Provides adjustable reset threshold and timeout periods using external resistors and capacitors
• Integrates a watchdog timer with a selectable 500x timeout multiplier option
• Features immunity to power-supply transients to prevent false resets
• Delivers an active-high, push-pull reset output signal

Supervisors Applications

• Critical microprocessor monitoring in embedded systems
• Portable battery-powered computers and equipment
• Medical equipment requiring reliable power supervision
• Intelligent instruments and set-top boxes

Supervisors Procurement Notes

Verify the specific suffix and manufacturer documentation carefully, as the MAX6304 family includes variants with different output structures. Confirm availability status, as some distributors indicate limited or discontinued stock for this part number. Ensure the selected variant matches the required active-high output configuration and package type before procurement.

Supervisors Selection Notes

Select this component when an adjustable reset threshold above 1.22V is required alongside watchdog functionality. Compare supply current requirements against other supervisory circuits if ultra-low power is critical. Verify that the SOIC-8 package fits the board layout constraints. Consider the 4ms reset delay and 2% accuracy specifications against system timing requirements.

Supervisors Part Context

The MAX6304CSA+ belongs to the MAX6301–MAX6304 family of low-power µP supervisory circuits. These devices are distinguished primarily by their reset output structure; the MAX6304 specifically provides an active-high output. The family shares common features such as adjustable timeouts and transient immunity, offering design flexibility for various microprocessor applications.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers for the MAX6304CSA+ were not identified in the provided source material. Designers should consult official Analog Devices documentation for potential pin-compatible or functionally equivalent alternatives.
