MAX6304CPA

Supervisors Overview

The MAX6304CPA is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.1V to 5.5V and features an adjustable reset threshold with 2% accuracy. The device provides a push-pull, active-high output and includes a built-in watchdog timer. Key electrical parameters include a 4ms reset delay time, 4µA operating current, and operation across a temperature range of -40°C to +85°C. It is housed in an 8-pin PDIP package.

Supervisors Feature Summary

• Provides robust power-system supervision for safety-critical applications
• Features an adjustable factory-set reset threshold for monitoring voltages from 1.1V to 5V
• Integrates a watchdog timer for system reliability

Supervisors Applications

• Safety-critical automotive applications
• Microprocessor system supervision
• Low-power embedded systems requiring voltage monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the presence of obsolete status. Confirm that the specific suffix corresponds to the lead-free and RoHS-compliant variant as indicated by the plus sign in related part numbers. Request original datasheets and test reports to ensure compliance with specified electrical characteristics before integration into production designs.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an adjustable threshold is required for systems operating between 1.1V and 5.5V. Consider the 4µA quiescent current for battery-powered designs. Ensure the application requires a push-pull output and does not need manual reset functionality. Verify that the 8-pin PDIP package fits the available PCB footprint and assembly constraints.

Supervisors Part Context

This part belongs to the MAX6304 series of low-power supervisory circuits designed for microprocessor systems. It serves as a voltage monitor that generates a reset signal when supply voltage drops below a set threshold. The series is characterized by low power consumption and integrated watchdog capabilities, making it suitable for portable and industrial electronics where reliable power management is essential.

Supervisors Replacement Considerations

Check for MAX6304EPA+ as a potential equivalent variant within the same family. Verify pin compatibility and electrical specifications against the target design requirements before substitution.
