MAX6304CUA+T

Supervisors Overview

The MAX6304CUA+T is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage supply and provides a reset signal with an adjustable watchdog timer. The device operates within a supply voltage range of 2.9V to 5.5V and features a fixed threshold voltage of 4.63V for the supervisor channel. It includes a manual reset input and offers a push-pull output configuration. The component is housed in an 8-uMAX package and is designed for operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a voltage supervisor with an adjustable watchdog timer for comprehensive system protection
• Features a manual reset input allowing for user-initiated system resets
• Provides a push-pull active-low output for direct interfacing with digital logic

Supervisors Applications

• Portable equipment requiring low-power voltage monitoring
• Battery-powered systems needing reliable reset generation
• Microcontroller-based designs requiring watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix 'UA' confirms the 8-uMAX package type when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as '+T' indicates tape-and-reel packaging which may affect handling requirements. Ensure the single-supervisor configuration meets your design needs, as other variants in the series may offer multiple channels or different thresholds.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog is required. The fixed 4.63V threshold suits 5V systems. Consider the 8-uMAX package size for space-constrained PCB layouts. Verify that the adjustable watchdog timeout aligns with your microcontroller's clock speed and operational requirements compared to fixed-timeout alternatives.

Supervisors Part Context

This part belongs to the MAX6303/MAX6304 family of supervisory circuits from Maxim Integrated. These devices are designed for low-voltage applications, offering both voltage supervision and watchdog timer functions in compact packages. The MAX6304 variant specifically includes the adjustable watchdog feature, distinguishing it from the simpler MAX6303 model.

Supervisors Replacement Considerations

Check for MAX6303CUA+T if watchdog functionality is not needed. Verify pin compatibility with MAX6305/6306 series if additional channels are required. Ensure substitute parts support the same 8-uMAX package and operating temperature range.
