Key Parameters

Substitute Part Grouping Explanation

The MIC59P60YN qualifies as a direct substitute for the MIC59P60BN based on the following critical parameters that determine functional equivalence:

Core Electrical Parameters (Matching):

• Switch Type: Latched Driver
• Number of Outputs: 8
• Ratio - Input:Output: 1:8
• Output Configuration: Low Side
• Output Type: Bipolar
• Interface: Strobe, Serial
• Current - Output (Max): 500mA
• Features: Status Flag
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Voltage - Load Specification: The MIC59P60YN operates within 5V ~ 12V load voltage range, which is a subset of the MIC59P60BN's 15V maximum specification. This represents a more restrictive operating window but maintains compatibility for applications within the 5V ~ 12V range.

Compliance Differentiation: The MIC59P60YN is ROHS3 Compliant and carries Active product status, whereas the MIC59P60BN is RoHS non-compliant and Obsolete. This distinction is significant for new designs and regulated applications.

Parameter Comparison

Engineering Selection Recommendations

For Existing Systems Using MIC59P60BN: The MIC59P60YN serves as the direct functional replacement when load voltage requirements do not exceed 12V. The identical pin configuration, package footprint, and electrical characteristics enable direct substitution in through-hole PCB designs. The MIC59P60YN's Active product status ensures continued availability and manufacturing support.

For New Designs: The MIC59P60YN is the recommended selection due to its Active product status and ROHS3 compliance. This choice aligns with current regulatory requirements and supply chain sustainability. Applications requiring load voltages above 12V must evaluate alternative driver solutions outside this product family.

Compliance Considerations: The transition from MIC59P60BN (RoHS non-compliant) to MIC59P60YN (ROHS3 Compliant) addresses regulatory requirements for products destined for markets with RoHS directives. The MIC59P60YN's enhanced fault protection through fixed current limiting provides additional circuit protection compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can MIC59P60YN replace MIC59P60BN in all applications? A: The MIC59P60YN is a direct substitute for applications where load voltage remains within 5V ~ 12V. Applications requiring the full 15V load voltage capability of the MIC59P60BN require alternative component selection.

Q: What is the significance of the voltage difference between these parts? A: The MIC59P60BN supports load voltages up to 15V, while the MIC59P60YN operates within 5V ~ 12V. This represents a design refinement in the product line. Verify your application's load voltage specification before substitution.

Q: Are the pin configurations identical between MIC59P60BN and MIC59P60YN? A: Both parts use the 20-DIP package with identical pin assignments. Direct PCB substitution is possible without layout modifications.

Q: What additional protection does MIC59P60YN provide? A: The MIC59P60YN includes fixed current limiting in addition to over-temperature and UVLO protection present in the MIC59P60BN. This enhancement provides improved fault tolerance.

Q: Why is MIC59P60BN classified as obsolete? A: The MIC59P60BN has been superseded by the MIC59P60YN, which offers improved compliance status and enhanced protection features. Microchip Technology has transitioned production to the newer variant.

Q: Is the packaging format important for substitution? A: The MIC59P60YN is supplied in Tube packaging, while the MIC59P60BN packaging format was not specified. Both use identical 20-DIP through-hole packages suitable for standard PCB assembly processes.
