MIC706PM-TR Equivalent & Substitute Parts

Part Overview

The MIC706PM-TR is a single-channel power management supervisor IC manufactured by Microchip Technology, housed in an 8-SOIC surface mount package. This device functions as a reset/power-on reset circuit with a 2.63V voltage threshold and 140ms minimum reset timeout, operating across the industrial temperature range of -40°C to 85°C. The MIC706PM-TR is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC706PM-TR is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — mechanical and electrical compatibility
• Mounting Type: Surface Mount — PCB assembly compatibility
• Number of Voltages Monitored: 1 — functional scope
• Operating Temperature Range: -40°C ~ 85°C (TA) — environmental operating conditions
• Voltage - Threshold: 2.63V — circuit protection threshold
• Reset Logic: Active Low — signal polarity compatibility
• Reset Timeout: 140ms Minimum — timing specification

Substitute parts are grouped into two categories based on output configuration and reset polarity:

Category A: Active Low Reset with Push-Pull Output (Closest Functional Match)

• ADM706ARZ-REEL7
• DS1706PESA+
• MAX706PESA+

These parts maintain the 2.63V threshold and Active Low reset logic of the original MIC706PM-TR while offering Push-Pull output configuration and improved RoHS3 compliance.

Category B: Active High Reset with Push-Pull Output (Functional Variant)

• ADM706PARZ-REEL
• MAX706PCSA+

These parts share the 2.63V threshold but feature Active High reset logic, requiring circuit-level evaluation for compatibility.

Category C: Alternate Threshold (4.4V) with Active Low Reset

• ADM706ARZ
• ADM706ARZ-REEL

These parts maintain Active Low reset logic but operate at 4.4V threshold, suitable only for applications where the higher threshold is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DS1706PESA+ or MAX706PESA+

Both DS1706PESA+ and MAX706PESA+ provide the closest functional equivalence to the MIC706PM-TR. These parts maintain the 2.63V voltage threshold, support the full -40°C to 85°C operating temperature range, and are ROHS3 compliant. The DS1706PESA+ offers a 130ms minimum reset timeout, while MAX706PESA+ matches the original 140ms specification. Both feature Push-Pull output configuration and are available in active product status with substantial inventory.

Secondary Recommendation: ADM706ARZ-REEL7

The ADM706ARZ-REEL7 operates at a 4.4V threshold with Active Low reset logic and 160ms minimum reset timeout. This part is suitable for applications where the higher voltage threshold is acceptable and provides the highest inventory availability (27,036 units). ROHS3 compliance and full temperature range support are confirmed.

Alternative for Active High Reset Logic: ADM706PARZ-REEL or MAX706PCSA+

If circuit design requires Active High reset logic, ADM706PARZ-REEL maintains the 2.63V threshold with 160ms reset timeout and full temperature range. MAX706PCSA+ also supports 2.63V threshold and 140ms reset timeout but operates within the 0°C to 70°C temperature range, limiting use in extended industrial applications.

Compliance Consideration:

All recommended substitutes are ROHS3 compliant, addressing environmental regulatory requirements that the original MIC706PM-TR does not meet. This upgrade improves long-term supply chain sustainability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can ADM706ARZ or ADM706ARZ-REEL be used as direct replacements for MIC706PM-TR?

A: These parts share the 8-SOIC package and Active Low reset logic but operate at 4.4V threshold instead of 2.63V. Direct substitution is possible only if the application circuit is designed to tolerate the higher voltage threshold. Circuit-level evaluation is required.

Q: What is the difference between ADM706ARZ-REEL and ADM706ARZ-REEL7?

A: Both parts are functionally identical with 4.4V threshold and Active Low reset. The primary difference is packaging designation and inventory availability. ADM706ARZ-REEL7 has significantly higher stock (27,036 units vs. 12,600 units).

Q: Why do some substitutes have Active High reset logic instead of Active Low?

A: ADM706PARZ-REEL and MAX706PCSA+ feature Active High reset logic, which inverts the signal polarity compared to the MIC706PM-TR. These parts are suitable only for applications where the reset circuit is designed to accommodate inverted logic. Verify circuit compatibility before selection.

Q: Is the 160ms reset timeout of ADM706ARZ-REEL7 compatible with the 140ms specification of MIC706PM-TR?

A: The ADM706ARZ-REEL7 specifies 160ms minimum reset timeout, which is longer than the original 140ms. This extended timeout is generally compatible with most applications but should be evaluated against specific system requirements for reset timing criticality.

Q: What is the impact of the operating temperature range difference in MAX706PCSA+?

A: MAX706PCSA+ operates within 0°C to 70°C, which is narrower than the MIC706PM-TR range of -40°C to 85°C. This part is unsuitable for applications requiring extended industrial temperature operation or cold-start conditions below 0°C.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts are ROHS3 compliant. The original MIC706PM-TR is RoHS non-compliant. Substitution provides regulatory compliance improvement for new designs or product updates.

Q: Can I use DS1706PESA+ in place of MAX706PESA+ if both have 2.63V threshold?

A: Both parts are functionally equivalent with 2.63V threshold and full temperature range support. DS1706PESA+ specifies 130ms minimum reset timeout, while MAX706PESA+ specifies 140ms. Selection depends on whether the shorter timeout of DS1706PESA+ is acceptable for the application.
