MAX6303CUA+T

Supervisors Overview

The MAX6303CUA+T is a low-power supervisory circuit designed for +5V systems, housed in an 8-pin uMAX package. It features an adjustable reset threshold and includes a watchdog timer with a minimum timeout of 2.8 ms. The device operates within a supply voltage range up to 5.5 V and consumes only 4 µA of quiescent current. It provides an active-low, push-pull output and supports manual reset functionality. The component functions reliably across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer with adjustable reset thresholds for system monitoring
• Operates with ultra-low power consumption suitable for battery-backed applications
• Provides active-low push-pull output with manual reset input capability

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Microprocessor-based systems needing watchdog protection
• Battery-operated equipment with +5V logic levels

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'C' grade corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with the required reset delay and watchdog timeout specifications for your design. Check for RoHS compliance status as indicated by the '+' suffix in the part number.

Supervisors Selection Notes

Select this component when a single-supervisor IC with integrated watchdog functionality is required. It is suitable for designs where low quiescent current is critical. Consider the adjustable reset threshold if standard fixed thresholds do not match the target voltage. Verify that the uMAX package fits the available PCB space constraints.

Supervisors Part Context

This part belongs to the MAX6303 series of supervisory circuits from Maxim Integrated. It is specifically engineered for +5V applications, distinguishing it from lower-voltage variants in the broader portfolio. The uMAX package offers a compact solution for space-constrained designs compared to larger SOIC or DIP options.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6303 family, such as the MAX6303CSA+T, which uses an SOIC-8 package. Verify that any substitute maintains the same adjustable threshold and watchdog timing characteristics.
