AP2820FMMTR-G1 Equivalent & Substitute Parts

Part Overview

The AP2820FMMTR-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 as a 2.5A power switch with integrated fault protection including current limiting, over-temperature protection, reverse current blocking, and UVLO (Under-Voltage Lock-Out). The product is currently 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 AP2820FMMTR-G1 is determined by strict alignment of the following critical parameters:

• Switch Type & Configuration: USB Switch with high-side N-channel output, 1:1 input-to-output ratio
• Current Rating: Maximum output current of 2.5A
• Voltage Range: Load voltage operating window of 2.7V to 5.5V minimum
• Fault Protection Suite: Current limiting, over-temperature protection, reverse current blocking, and UVLO functionality
• Package Compatibility: 8-pin TSSOP or 8-MSOP package with 0.118" (3.00mm) width
• Compliance Standards: ROHS3 compliance and surface mount mounting type

The BD82024FVJ-E2 manufactured by Rohm Semiconductor meets all substitution criteria within these defined parameters. This part maintains functional equivalence across all specified electrical and mechanical characteristics while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The BD82024FVJ-E2 is a direct functional substitute for the obsolete AP2820FMMTR-G1. Both components maintain identical electrical specifications across current rating, voltage operating range, fault protection architecture, and thermal operating window. Both parts carry ROHS3 compliance certification and REACH unaffected status, ensuring regulatory alignment for production applications.

The BD82024FVJ-E2 offers the advantage of active product status with significantly higher inventory availability (8137 pieces in stock versus 840 pieces for the main part). The substitute part includes an additional load discharge feature not present in the main part, providing enhanced circuit protection capability. The minimum load voltage specification differs by 0.1V (2.8V versus 2.7V), which remains compatible with standard USB power delivery applications. The on-resistance specification (90mOhm typical versus 60mOhm typical) represents a measurable but acceptable trade-off within the 2.5A current class for USB switching applications.

Frequently Asked Questions (FAQ)

Q: Can the BD82024FVJ-E2 directly replace the AP2820FMMTR-G1 in existing designs?

A: Yes. Both parts share identical switch type classification, output configuration, current rating, fault protection suite, operating temperature range, and package dimensions. The electrical parameters align within acceptable tolerances for USB switching applications.

Q: What is the significance of the 30mOhm difference in Rds On specification?

A: The BD82024FVJ-E2 specifies 90mOhm typical on-resistance compared to 60mOhm for the AP2820FMMTR-G1. At maximum rated current (2.5A), this results in approximately 0.075W additional power dissipation in the substitute part. This difference remains within acceptable limits for USB power switch applications and does not alter functional compatibility.

Q: Does the load voltage range difference (2.8V minimum versus 2.7V minimum) affect compatibility?

A: The BD82024FVJ-E2 minimum load voltage specification of 2.8V is compatible with standard USB power delivery applications, which operate at 5V nominal. The 0.1V difference does not impact functionality in typical USB switching circuits.

Q: What additional protection does the load discharge feature provide?

A: The BD82024FVJ-E2 includes load discharge capability in addition to the standard fault protection features present in both parts. This feature provides enhanced circuit protection by actively discharging the load when the switch is disabled, reducing potential voltage transients.

Q: Are both parts available in the same package options?

A: Yes. Both the AP2820FMMTR-G1 and BD82024FVJ-E2 are available in 8-TSSOP and 8-MSOP packages with identical 0.118" (3.00mm) width specifications, ensuring PCB layout compatibility.

Q: What is the inventory status difference between these parts?

A: The AP2820FMMTR-G1 is classified as obsolete with 840 pieces currently in stock. The BD82024FVJ-E2 maintains active product status with 8137 pieces in stock, providing superior long-term availability for production applications.
