MAX6302CUA+

Supervisors Overview

The MAX6302CUA+ is a single-channel supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5 V to 5.5 V and features an adjustable threshold for monitoring power rails. The device provides a reset output with a minimum timeout of 2.8 ms, available in active high or open drain/open collector configurations. It is housed in an 8-uMAX/uSOP surface-mount package and supports an operating temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for microprocessors and memory systems
• Features an adjustable voltage threshold to accommodate various system supply voltages
• Offers flexible output configuration with options for active high, open drain, or open collector signals

Supervisors Applications

• Microprocessor reset circuits
• Memory protection systems
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix 'CUA+' against the official Maxim Integrated datasheet to confirm the package type and temperature grade. Ensure the design requires the 0°C to 70°C industrial range rather than extended variants. Cross-reference the adjustable threshold requirements with the specific resistor network intended for the application to guarantee compliance with the component's electrical specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an adjustable threshold is required for low-power applications. The 8-uMAX package suits space-constrained designs. Consider the 2.8 ms minimum reset timeout when designing for fast-startup systems. Verify that the open drain or active high output option aligns with the downstream logic interface requirements of the target microcontroller or processor.

Supervisors Part Context

This part belongs to the MAX6301-04 series of low-power microprocessor supervisory circuits. These devices are designed to monitor voltage levels and generate reset signals to ensure reliable system operation. The MAX6302 variant specifically offers adjustable thresholds, providing flexibility for different supply rail requirements compared to fixed-voltage counterparts in the same family.

Supervisors Replacement Considerations

Publicly confirmed direct substitutes include other MAX6302 variants with compatible packages such as MAX6302ESA+. Verify pin compatibility and electrical parameters before substitution.
