MAX6303EPA+

Supervisors Overview

The MAX6303EPA+ is a low-power, precision voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.24 V to 5.5 V and features an adjustable reset threshold voltage with 2% accuracy. The device provides a push-pull active-low output and includes a built-in watchdog timer for system reliability. It offers a fast reset delay time of 4 ms and consumes only 4 µA of quiescent current. Designed for through-hole mounting in an 8-PDIP package, it supports an industrial temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery without manual intervention
• Features adjustable reset threshold voltage with high precision accuracy
• Provides active-low push-pull output for direct logic interface compatibility
• Operates with ultra-low quiescent current consumption for power efficiency

Supervisors Applications

• Portable battery-powered instrumentation requiring extended battery life
• Embedded microprocessor systems needing reliable power supervision
• Industrial control units operating within standard temperature ranges
• Communication equipment requiring watchdog functionality for fault recovery

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance documentation matches specific revision requirements. Check for obsolescence notices as this part may be subject to discontinuation. Ensure packaging integrity upon receipt to prevent damage to the PDIP-8 leads during installation.

Supervisors Selection Notes

Select this component when adjustable reset thresholds are required alongside watchdog protection. Compare against fixed-threshold variants if precise voltage monitoring is not necessary. Consider the 4 µA current draw for strict power budget applications. Verify that the 0°C to +70°C temperature range meets environmental specifications for the target deployment scenario.

Supervisors Part Context

This supervisory circuit belongs to the MAX6303 series, designed for cost-effective power management solutions. It complements other Maxim Integrated PMIC offerings by providing essential reset generation and watchdog capabilities in a compact form factor. The series targets applications where system stability and low power consumption are critical design constraints.
