MIC707MY Equivalent & Substitute Parts

Part Overview

The MIC707MY is an active supervisor integrated circuit manufactured by Microchip Technology, designed for power management applications requiring single-channel voltage monitoring and reset signal generation. This 8-SOIC surface mount device operates across the industrial temperature range of -40°C to 85°C and provides complementary output configuration for reset control logic. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when addressing supply chain constraints, packaging format requirements, or specific output stage configurations while maintaining functional equivalence in voltage monitoring and reset timing parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC707MY is determined by strict alignment across the following critical parameters:

Core Functional Requirements:

• Single-channel voltage monitoring capability
• 4.65V threshold voltage (±tolerance variations acceptable within standard component specifications)
• Active High/Active Low reset logic support
• 140ms minimum reset timeout (or lower values acceptable for faster response)
• 8-SOIC package format with identical 0.154" width (3.90mm)

Environmental Compatibility:

• Operating temperature range must encompass or match -40°C to 85°C industrial specification
• ROHS3 compliance mandatory
• MSL 1 rating required

Output Stage Consideration: The MIC707MY employs complementary output configuration. Substitute parts with Push-Pull output stages remain functionally compatible as both configurations provide dual-state reset signal control, though output impedance characteristics may differ. This difference does not prevent direct substitution in standard reset circuit applications.

All identified substitute parts meet these core requirements while maintaining active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Full Industrial Temperature Range (-40°C to 85°C): DS1707ESA+, MAX707ESA+, MAX707ESA+T, and TPS3707-50DR maintain the complete industrial operating temperature specification. These parts are suitable for applications requiring extended temperature performance across the full range specified for MIC707MY.

Commercial Temperature Range (0°C to 70°C): MAX707CSA+ and MAX707CSA+T operate within commercial temperature limits. These parts are suitable only for applications where operating conditions remain within 0°C to 70°C boundaries.

Packaging Format Considerations: Tube packaging (MIC707MY, DS1707ESA+, MAX707CSA+, MAX707ESA+) supports standard component handling and storage. Cut Tape and Digi-Reel formats (MAX707CSA+T, MAX707ESA+T, TPS3707-50DR) accommodate automated assembly processes and reel-based component dispensing systems.

Voltage Threshold Alignment: All substitute parts maintain 4.65V threshold specification except TPS3707-50DR, which specifies 4.55V. This 0.10V variance remains within typical component tolerance bands and does not prevent functional substitution in standard applications.

Reset Timeout Performance: DS1707ESA+ specifies 130ms minimum reset timeout, which is 10ms faster than MIC707MY. All other substitutes match or exceed the 140ms minimum specification. Faster reset timing does not compromise functionality in standard reset circuit applications.

All substitute parts maintain active product status and ROHS3 compliance, confirming ongoing manufacturing support and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can MAX707CSA+ or MAX707CSA+T be used in applications requiring -40°C operation?

A: No. MAX707CSA+ and MAX707CSA+T specify 0°C to 70°C operating range and are not rated for temperatures below 0°C. For applications requiring full industrial temperature range, use DS1707ESA+, MAX707ESA+, MAX707ESA+T, or TPS3707-50DR.

Q: What is the functional difference between complementary and push-pull output configurations?

A: Both configurations provide dual-state reset signal control. Complementary output uses one active stage; push-pull uses two complementary stages. Both are functionally compatible in standard reset circuit applications. Output impedance characteristics may differ slightly between configurations.

Q: Is the 0.10V threshold difference between MIC707MY (4.65V) and TPS3707-50DR (4.55V) significant?

A: The 0.10V variance falls within standard component tolerance specifications and does not prevent functional substitution. Both parts monitor the same voltage rail and provide reset control at thresholds within acceptable engineering margins for typical power supply applications.

Q: Can I substitute tube-packaged parts with cut tape/Digi-Reel formats?

A: Yes. Both packaging formats contain identical die and electrical specifications. Selection depends on assembly process requirements. Tube format suits manual or standard pick-and-place assembly; cut tape and Digi-Reel formats optimize automated high-volume production lines.

Q: Does DS1707ESA+ 130ms reset timeout create compatibility issues?

A: No. The 130ms timeout is faster than MIC707MY's 140ms specification. Faster reset timing does not compromise functionality and may improve system response in applications sensitive to power-on sequencing delays.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL 1 rating, confirming regulatory alignment with MIC707MY and suitability for current manufacturing standards.
