MIC706PN Equivalent & Substitute Parts

Part Overview

The MIC706PN is a supervisor integrated circuit from Microchip Technology designed for power management applications. It functions as a single-channel power-on reset (POR) circuit with active-low reset output, operating across industrial temperature ranges. The MIC706PN is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The DS1706PEPA+ from Analog Devices Inc./Maxim Integrated serves as the primary manufacturer-recommended substitute.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC706PN is determined by the following critical parameters:

• Package Compatibility: Both parts use 8-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and electrical pin compatibility
• Voltage Threshold: Both maintain 2.63V threshold voltage for supervisor operation
• Single-Channel Monitoring: Both monitor one voltage rail
• Operating Temperature Range: Both support -40°C ~ 85°C industrial temperature range
• Mounting Type: Both use through-hole mounting, compatible with existing PCB designs

The DS1706PEPA+ qualifies as a direct substitute based on these aligned parameters. Differences in reset polarity (active high vs. active low) and output type (push-pull vs. standard) require circuit-level evaluation but do not disqualify substitution when output logic is inverted or adapted in the application design.

Engineering Selection Recommendations

The DS1706PEPA+ is the manufacturer-recommended substitute for the obsolete MIC706PN. Selection should be based on the following factors:

Product Status: The MIC706PN is obsolete, making the DS1706PEPA+ the active alternative for new designs and production continuity.

Compliance and Certifications: The DS1706PEPA+ is ROHS3 compliant, whereas the MIC706PN is RoHS non-compliant. For applications subject to RoHS regulations, the DS1706PEPA+ is the required choice.

Reset Polarity Consideration: The DS1706PEPA+ features active-high reset output compared to the MIC706PN's active-low output. Circuit designs must accommodate this polarity difference through logic inversion or output buffering as appropriate for the application.

Output Configuration: The DS1706PEPA+ provides push-pull, totem-pole output, offering improved drive capability compared to standard output configurations.

Electrical Equivalence: Both parts maintain identical voltage thresholds (2.63V), single-channel monitoring, and operating temperature ranges, ensuring functional compatibility in supervisor applications.

Frequently Asked Questions (FAQ)

Q: Can the DS1706PEPA+ be used as a direct pin-for-pin replacement for the MIC706PN?

A: The DS1706PEPA+ shares the same 8-DIP package and pinout as the MIC706PN. However, the reset output polarity differs (active high vs. active low), requiring circuit-level adaptation. Pin compatibility exists, but logic inversion may be necessary depending on the application's reset signal requirements.

Q: What is the primary reason for substituting the MIC706PN?

A: The MIC706PN is classified as obsolete. The DS1706PEPA+ is the active, manufacturer-recommended substitute to ensure design continuity and component availability.

Q: Are there compliance differences between these parts?

A: Yes. The MIC706PN is RoHS non-compliant, while the DS1706PEPA+ is ROHS3 compliant. For applications requiring RoHS compliance, the DS1706PEPA+ is mandatory.

Q: How do the reset timeout specifications compare?

A: The MIC706PN specifies 140ms minimum reset timeout, while the DS1706PEPA+ specifies 130ms minimum. Both values fall within typical supervisor circuit specifications. Application designs should account for this 10ms difference if timing-critical reset sequencing is required.

Q: What is the difference between active-low and active-high reset outputs?

A: Active-low reset means the reset signal is asserted (active) when low and de-asserted when high. Active-high reset operates inversely. The MIC706PN uses active-low; the DS1706PEPA+ uses active-high. Circuit designs must invert the logic signal or use appropriate buffering to maintain correct reset behavior.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the MIC706PN and DS1706PEPA+ operate across -40°C ~ 85°C, meeting industrial temperature requirements.

Q: What packaging considerations apply to these supervisor ICs?

A: Both parts use 8-DIP (0.300", 7.62mm) through-hole packaging. PCB layouts designed for the MIC706PN require no physical modifications to accommodate the DS1706PEPA+. Electrical schematic modifications are necessary only to address reset polarity differences.
