AP2820FMM-G1 Equivalent & Substitute Parts

Part Overview

The AP2820FMM-G1 is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 input-to-output ratio and high-side N-channel output configuration. This component operates at 2.5A maximum output current with integrated fault protection including current limiting, over-temperature protection, reverse current blocking, and UVLO (Under-Voltage Lock-Out). The AP2820FMM-G1 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP2820FMM-G1 is determined by strict equivalence across the following critical parameters:

Functional Requirements:

• Switch Type: USB Switch
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Output Type: N-Channel
• Interface: On/Off
• Input Type: Non-Inverting

Electrical Performance Boundaries:

• Voltage - Load: Minimum 2.7V (substitute must support ≥2.7V)
• Current - Output (Max): 2.5A (substitute must support ≥2.5A)
• Rds On (Typ): 60mOhm (substitute performance acceptable within operational limits)
• Operating Temperature: -40°C ~ 85°C (TA)

Protection & Features:

• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO (all required)
• Features: Status Flag capability

Physical & Compliance:

• Mounting Type: Surface Mount
• Package / Case: 8-TSSOP or 8-MSOP compatible footprints
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The BD82024FVJ-E2 from Rohm Semiconductor meets all substitution criteria with compatible electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The BD82024FVJ-E2 is the direct substitute for the obsolete AP2820FMM-G1. Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance. The BD82024FVJ-E2 maintains active product status with 8137 units in stock, providing supply continuity.

Key considerations for selection:

Electrical Compatibility: The BD82024FVJ-E2 supports the required voltage range (2.8V ~ 5.5V minimum vs. 2.7V ~ 5.5V original), matching the 2.5A output current specification. The higher Rds On value (90mOhm vs. 60mOhm) remains within acceptable operational parameters for USB switching applications.

Feature Enhancement: The BD82024FVJ-E2 includes Load Discharge functionality in addition to the Status Flag present in the AP2820FMM-G1, providing additional circuit protection capability.

Package Compatibility: Both components use identical 8-TSSOP/8-MSOP footprints (0.118", 3.00mm Width), enabling direct PCB layout compatibility without redesign.

Supply Status: The transition from obsolete to active product status ensures long-term availability and manufacturing support for the BD82024FVJ-E2.

Frequently Asked Questions (FAQ)

Q: Can the BD82024FVJ-E2 directly replace the AP2820FMM-G1 without PCB modifications?

A: Yes. Both components share identical 8-TSSOP/8-MSOP footprints with 0.118" (3.00mm) width, enabling direct pin-compatible substitution without PCB layout changes.

Q: What is the impact of the higher Rds On value (90mOhm vs. 60mOhm) in the BD82024FVJ-E2?

A: The BD82024FVJ-E2 maintains the same 2.5A maximum output current specification. The increased on-resistance results in higher power dissipation under load. Thermal analysis should confirm that existing thermal management (PCB copper area, heatsinking) remains adequate for your application's duty cycle.

Q: Are there compliance differences between the two parts?

A: No. Both the AP2820FMM-G1 and BD82024FVJ-E2 are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance for production and field deployment.

Q: What is the minimum load voltage supported by the BD82024FVJ-E2?

A: The BD82024FVJ-E2 supports load voltages from 2.8V to 5.5V. The original AP2820FMM-G1 specified 2.7V minimum. Applications operating below 2.8V require design review to confirm compatibility.

Q: Does the BD82024FVJ-E2 include all fault protection features of the AP2820FMM-G1?

A: Yes. Both components include Current Limiting (Fixed), Over Temperature protection, Reverse Current blocking, and UVLO (Under-Voltage Lock-Out). The BD82024FVJ-E2 adds Load Discharge functionality.

Q: What packaging options are available for the BD82024FVJ-E2?

A: The BD82024FVJ-E2 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, with 8137 units currently in stock.
