MAX706SEPA+

Supervisors Overview

The MAX706SEPA+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for voltage monitoring applications. It features a threshold voltage of 2.63 V and supports a maximum supply voltage of 5.5 V. The device operates within a temperature range of -40°C to +85°C and consumes 135 µA of working current. It provides power-fail detection with an overvoltage threshold of 2.7 V. The reset delay time is specified at 200 ms, and the accuracy is rated at 2.5%. This component utilizes a PDIP-8 package and offers active high, push-pull output types.

Supervisors Feature Summary

• Integrated manual reset input capability for controlled system recovery
• Built-in watchdog timer functionality for automated fault recovery
• Dedicated power-fail warning output for proactive voltage monitoring

Supervisors Applications

• Desktop computer systems
• Portable battery-powered equipment
• Test and measurement instruments
• Multi-output power supplies

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or restricted supply conditions. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Ensure the specific ordering suffix matches the required package type and pin configuration for the target application design.

Supervisors Selection Notes

Select this component when a low-cost supervisory solution with manual reset and watchdog features is required. Consider the 2.63 V threshold and 2.5% accuracy for precise voltage monitoring needs. Evaluate the PDIP-8 package constraints against board space requirements and thermal performance expectations within the operational temperature range.

Supervisors Part Context

This part belongs to the MAX706 series of microprocessor supervisory circuits from Maxim Integrated. It is distinct from similar models like the MAX706TEUA+ which uses a UMAX-8 package, or the DS1708SEPA+ which lacks a watchdog timer. The SEPA+ designation specifically denotes the through-hole PDIP-8 packaging variant with integrated manual reset and watchdog capabilities.

Supervisors Replacement Considerations

Direct substitutes include the MAX706PESA+ which shares similar through-hole characteristics but differs in output polarity and threshold settings. For surface-mount alternatives, consider the MAX706SESA+ or MAX706SESA+T variants, noting the package change from PDIP to SOIC.
