MAX6303CPA+

Supervisors Overview

The MAX6303CPA+ is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.7V to 5.5V and features an adjustable threshold voltage starting at 1.24V. The device provides an active-low, push-pull output with a reset delay time of 4ms and a minimum timeout of 2.8ms. It integrates a watchdog timer function and consumes only 4µA of operating current. Packaged in an 8-PDIP through-hole housing, it supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring alongside standard voltage supervision.
• Features an adjustable selectable threshold voltage to accommodate various power rail requirements.
• Provides an active-low push-pull output compatible with standard digital logic interfaces.

Supervisors Applications

• Microprocessor power supply monitoring
• Watchdog timer implementation in embedded systems
• Battery-powered device supervision

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity as units may be surplus stock. Check RoHS compliance documentation for specific manufacturing lot dates. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when adjustable reset thresholds and integrated watchdog functionality are required. Consider the low quiescent current for battery-operated applications. Verify that the through-hole PDIP-8 package fits the design constraints. Compare against fixed-threshold alternatives if programmability is not needed.

Supervisors Part Context

Part of the MAX6301-04 series of low-power supervisory circuits. Designed for general-purpose microprocessor reset generation. Shares family characteristics such as low power consumption and compact packaging. Differentiated by its specific adjustable threshold and watchdog integration capabilities.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX630x series. Verify equivalent threshold adjustability and watchdog timing specifications. Ensure replacement parts maintain the same active-low output polarity and push-pull drive capability.

Supervisors FAQ

Does the MAX6303CPA+ include a manual reset input?

No, the MAX6303CPA+ does not support manual reset inputs; it relies on automatic power-on reset and watchdog triggering.

What is the typical operating current of the MAX6303CPA+?
