MIC2546-2YTS Equivalent & Substitute Parts

Part Overview

The MIC2546-2YTS is an active N-Channel power switch driver manufactured by Microchip Technology, designed for USB switching applications. This 16-TSSOP surface mount component delivers 1.5A maximum output current with integrated status flag and comprehensive fault protection including current limiting, over-temperature, and reverse current protection. The device operates across a 2.7V to 5.5V load voltage range with typical on-resistance of 80mOhm.

The MIC2546-2YTS maintains Active product status with ROHS3 compliance and is currently in stock. Equivalent substitute parts are available to address inventory requirements, packaging preferences, or moisture sensitivity specifications.

Substitute Part Grouping Explanation

Substitute parts for the MIC2546-2YTS are determined by equivalence across the following critical parameters:

• Switch Type: USB Switch
• Output Type: N-Channel
• Number of Outputs: 2
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Current - Output (Max): 1.5A
• Voltage - Load: 2.7V ~ 5.5V
• Rds On (Typ): 80mOhm
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain identical electrical specifications and mechanical compatibility. Variations in Moisture Sensitivity Level (MSL) and inventory availability are noted but do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for equivalent substitution in applications requiring N-Channel USB power switching at 1.5A with 1:1 input-output ratio and high-side output configuration.

MIC2546-1YTS and MIC2547-2YTS offer improved moisture sensitivity specifications (MSL 1 - Unlimited) compared to the primary MIC2546-2YTS (MSL 3 - 168 Hours), providing extended shelf life and reduced moisture-related handling constraints. Selection between these alternatives should be based on inventory availability, lead time requirements, and specific application storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MIC2546-1YTS replace MIC2546-2YTS in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including output current, voltage range, on-resistance, and package configuration. The primary difference is moisture sensitivity level, where MIC2546-1YTS provides unlimited shelf life versus 168 hours for MIC2546-2YTS.

Q: What is the difference between MIC2546-2YTS and MIC2547-2YTS?

A: Both parts share identical electrical specifications and 16-TSSOP packaging. The base product number differs (MIC2546 versus MIC2547), but functional parameters for USB switching applications remain equivalent. MIC2547-2YTS offers improved moisture sensitivity (MSL 1 - Unlimited).

Q: Are all substitute parts in the same package?

A: Yes. All three parts use 16-TSSOP surface mount packaging with 0.173" width and 4.40mm dimensions, ensuring direct PCB compatibility without layout modifications.

Q: Do substitute parts maintain the same fault protection features?

A: Yes. All parts include identical fault protection: current limiting (adjustable), over-temperature protection, and reverse current protection, along with status flag functionality.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.
