MIC706N Equivalent & Substitute Parts

Part Overview

The MIC706N is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for power-on reset and system supervision applications. This device monitors a single voltage threshold at 4.4V and provides active-low reset output with a 140ms minimum timeout. The MIC706N is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence in voltage monitoring, reset timing, and package compatibility while meeting current compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC706N are selected based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

Critical Matching Parameters:

• Voltage threshold: 4.4V (all substitutes maintain this specification)
• Reset polarity: Active Low (all substitutes maintain this specification)
• Package type: 8-DIP (0.300", 7.62mm) (all substitutes use identical package)
• Mounting type: Through Hole (all substitutes maintain this specification)
• Number of voltages monitored: 1 channel (all substitutes maintain this specification)

Allowable Variation Parameters:

• Reset timeout: 140ms minimum (MIC706N) to 160ms minimum (ADM706ANZ) — both meet minimum timing requirements
• Operating temperature range: -40°C ~ 85°C (MIC706N and MAX706EPA+) versus 0°C ~ 70°C (MAX706CPA+) — temperature range selection depends on application requirements
• Output type: Open-drain (MIC706N) versus Push-Pull/Totem Pole (substitute parts) — output configuration change requires circuit evaluation
• Product status: Obsolete (MIC706N) versus Active (all substitutes) — substitutes are in active production

All substitute parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain the same functional category, pinout, and core supervision functionality as the original MIC706N.

Engineering Selection Recommendations

MAX706EPA+ is the primary recommended substitute for MIC706N applications. This part maintains identical electrical specifications including 4.4V threshold, 140ms reset timeout, and -40°C ~ 85°C operating temperature range. The MAX706EPA+ is in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. This part is suitable for designs requiring extended temperature range operation.

MAX706CPA+ is an alternative substitute for applications operating within the 0°C ~ 70°C temperature range. This part shares the same 4.4V threshold and 140ms reset timeout as the MIC706N but has a narrower operating temperature specification. The MAX706CPA+ is in active production with ROHS3 compliance. Selection of this part should be limited to applications where the reduced temperature range is acceptable.

ADM706ANZ is a functionally equivalent substitute manufactured by Analog Devices Inc. This part maintains the 4.4V threshold and -40°C ~ 85°C operating temperature range but specifies a 160ms minimum reset timeout compared to the MIC706N's 140ms. The ADM706ANZ is in active production with ROHS3 compliance. This part is suitable for applications where the extended reset timeout does not impact system requirements.

All substitute parts are in active production status, providing supply chain continuity and eliminating obsolescence risk associated with the MIC706N.

Frequently Asked Questions (FAQ)

Q: Can MAX706EPA+ directly replace MIC706N in existing designs?

A: Yes. The MAX706EPA+ maintains identical voltage threshold (4.4V), reset polarity (active low), reset timeout (140ms minimum), operating temperature range (-40°C ~ 85°C), and 8-DIP package configuration. Direct pin-for-pin substitution is possible. However, the output stage differs (push-pull versus open-drain), requiring circuit evaluation to confirm compatibility with existing pull-up resistor configurations.

Q: What is the difference between MAX706EPA+ and MAX706CPA+?

A: The primary difference is operating temperature range. MAX706EPA+ operates from -40°C ~ 85°C, while MAX706CPA+ operates from 0°C ~ 70°C. Both parts share identical voltage threshold (4.4V), reset timeout (140ms minimum), and 8-DIP package. Selection depends on application temperature requirements.

Q: Why does ADM706ANZ specify 160ms reset timeout instead of 140ms?

A: The ADM706ANZ maintains functional equivalence with a slightly extended reset timeout of 160ms minimum compared to the MIC706N's 140ms minimum. This difference does not affect substitution validity for most applications, as both timeouts provide adequate power supply stabilization. Applications with specific reset timing requirements should evaluate this parameter.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAX706EPA+, MAX706CPA+, and ADM706ANZ are all ROHS3 compliant. The original MIC706N is RoHS non-compliant. Substitution with any of these parts ensures regulatory compliance for new designs and production.

Q: Do substitute parts use the same package as MIC706N?

A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole package, identical to the MIC706N. Direct board-level substitution is possible without PCB redesign.

Q: What is the difference between open-drain and push-pull output configurations?

A: The MIC706N uses open-drain output, while substitute parts use push-pull (totem pole) output. Open-drain requires external pull-up resistor to pull the output high. Push-pull actively drives the output both high and low. Circuit evaluation is required to confirm compatibility with existing reset signal conditioning.
