MIC706TN Equivalent & Substitute Parts

Part Overview

The MIC706TN is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for power-on reset and supervisory functions in electronic systems. This device monitors a single voltage supply and provides active-low reset output with a 140ms minimum timeout. The MIC706TN is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC706TN are qualified based on the following critical parameters that determine functional equivalence:

• Single voltage monitoring channel: All substitutes must monitor exactly one voltage supply
• Voltage threshold of 3.08V: Substitutes must maintain the same threshold specification
• Active-low reset output: Reset signal polarity must remain active low
• Reset timeout minimum of 140ms: Substitutes must meet or exceed this timing specification
• 8-DIP through-hole package: Physical form factor and pin count must match for direct board-level replacement
• Operating temperature range compatibility: Substitutes must support the required thermal operating window

The identified substitute parts DS1706TEPA+ and MAX706TCPA+ meet these core functional and physical requirements, enabling direct replacement in applications requiring MIC706TN functionality.

Parameter Comparison

Engineering Selection Recommendations

MAX706TCPA+ is the primary substitute for new designs and ongoing system support. This part maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The MAX706TCPA+ matches the MIC706TN's 140ms reset timeout specification exactly and provides identical voltage threshold and reset polarity characteristics. The operating temperature range of 0°C ~ 70°C is narrower than the MIC706TN's -40°C ~ 85°C specification; applications requiring extended low-temperature operation below 0°C must account for this limitation.

DS1706TEPA+ serves as an alternative substitute with identical operating temperature range (-40°C ~ 85°C) matching the MIC706TN. However, this part carries obsolete product status, limiting its suitability for long-term procurement strategies. The DS1706TEPA+ reset timeout of 130ms minimum is 10ms shorter than the MIC706TN specification; system designs with timing-critical reset sequencing must evaluate this difference.

Both substitutes provide push-pull, totem-pole output configurations, offering improved drive capability compared to the MIC706TN's unspecified output type. All three parts share identical 8-DIP through-hole packaging, enabling direct board-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX706TCPA+ replace MIC706TN in all applications?

A: MAX706TCPA+ provides functional equivalence for most applications. The narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C) requires evaluation if your system operates below 0°C or above 70°C. All other critical parameters—voltage threshold, reset polarity, reset timeout, and package form factor—are compatible.

Q: What is the difference between DS1706TEPA+ and MAX706TCPA+?

A: Both parts meet the MIC706TN's core functional requirements. DS1706TEPA+ maintains the full -40°C ~ 85°C operating temperature range but carries obsolete product status. MAX706TCPA+ is actively manufactured with ROHS3 compliance, making it preferable for new designs. DS1706TEPA+ has a 130ms reset timeout versus MAX706TCPA+'s 140ms; timing-sensitive applications should account for this 10ms difference.

Q: Are these parts pin-compatible with MIC706TN?

A: All three parts use 8-DIP through-hole packaging with identical physical dimensions (0.300", 7.62mm). Pin compatibility requires verification against specific pinout diagrams for your application, as supervisor IC pinouts can vary between manufacturers despite identical package types.

Q: What does "push-pull, totem-pole output" mean for reset functionality?

A: Push-pull, totem-pole output provides active drive capability in both high and low states, offering improved noise immunity and faster signal transitions compared to open-drain or unspecified output configurations. This enhancement is beneficial for reset signal integrity in noisy environments.

Q: Why is the MIC706TN obsolete?

A: The MIC706TN is classified as obsolete by Microchip Technology. Substitute parts ensure continued system support and enable new designs requiring equivalent supervisory functionality. MAX706TCPA+ is the recommended long-term alternative due to its active product status.

Q: Does RoHS compliance affect substitution decisions?

A: The MIC706TN is RoHS non-compliant, while both substitute parts are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, MAX706TCPA+ or DS1706TEPA+ provide regulatory compliance. For legacy systems without RoHS mandates, compliance status does not affect functional substitution.
