AP2805AMMTR-G1 Equivalent & Substitute Parts

Part Overview

The AP2805AMMTR-G1 is an N-Channel power switch/driver manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 input-output ratio and high-side output configuration. This component operates across a 2.7V to 5.5V load voltage range with a maximum output current of 500mA and typical on-resistance of 60mOhm. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across switching characteristics, fault protection mechanisms, and thermal operating ranges while accommodating the 8-MSOP/8-TSSOP package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2805AMMTR-G1 is determined by the following critical parameters:

• Switch Architecture: N-Channel, high-side output configuration with 1:1 input-output ratio
• Voltage Compatibility: Load voltage range must encompass or be compatible with 2.7V ~ 5.5V specification
• Current Rating: Output current capacity must meet or exceed 500mA minimum requirement
• Fault Protection: Presence of current limiting, over-temperature protection, reverse current blocking, and UVLO functionality
• Package Compatibility: 8-TSSOP-BJ or 8-MSOP package form factor with 0.118" (3.00mm) width
• Operating Temperature: -40°C ~ 85°C thermal range
• Compliance: ROHS3 compliance and EAR99 classification

The three substitute parts (BD82028FVJ-GE2, BD82032FVJ-GE2, BD82065FVJ-LBE2) from Rohm Semiconductor meet these substitution criteria with enhanced current ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

BD82065FVJ-LBE2 is the primary substitute for applications requiring full voltage range compatibility. This part maintains the 2.7V ~ 5.5V load voltage specification of the original AP2805AMMTR-G1, ensuring compatibility with designs operating at lower supply voltages. The 1.5A output current rating provides 3x headroom over the 500mA requirement, with 70mOhm typical on-resistance. Active product status and MSL 1 rating support long-term supply chain stability and manufacturing flexibility.

BD82028FVJ-GE2 and BD82032FVJ-GE2 are suitable for applications where load voltage remains within the 4.5V ~ 5.5V range. BD82028FVJ-GE2 offers 1A output current with 72mOhm on-resistance, while BD82032FVJ-GE2 provides 2A output current at the same on-resistance specification. Both parts carry active product status and MSL 1 rating. Selection between these two depends on current margin requirements for the specific application.

All substitute parts maintain identical fault protection architecture (current limiting, over-temperature, reverse current, UVLO), operating temperature range (-40°C ~ 85°C), and ROHS3 compliance. Package compatibility is confirmed across 8-TSSOP-BJ form factor with 0.118" (3.00mm) width.

Frequently Asked Questions (FAQ)

Q: Can BD82028FVJ-GE2 or BD82032FVJ-GE2 be used in designs operating below 4.5V?

A: No. These parts specify a minimum load voltage of 4.5V. Applications requiring operation at 2.7V must use BD82065FVJ-LBE2, which maintains the original 2.7V ~ 5.5V voltage range.

Q: What is the impact of the higher on-resistance in substitute parts?

A: Substitute parts exhibit 70-72mOhm typical on-resistance compared to 60mOhm in the AP2805AMMTR-G1. This 10-20% increase results in proportionally higher power dissipation. For 500mA operation, the difference is approximately 5mW additional dissipation, which is typically negligible in USB switching applications.

Q: Are the substitute parts pin-compatible with the AP2805AMMTR-G1?

A: Yes. All substitute parts use the 8-TSSOP-BJ package with 0.118" (3.00mm) width, maintaining mechanical and electrical pin compatibility with the original 8-MSOP/8-TSSOP package.

Q: What is the significance of MSL rating differences?

A: The AP2805AMMTR-G1 carries MSL 3 (168-hour floor life), while all substitute parts carry MSL 1 (unlimited floor life). MSL 1 provides superior moisture handling and eliminates bake-out requirements, offering manufacturing process advantages.

Q: Which substitute part should be selected for new designs?

A: BD82065FVJ-LBE2 is recommended for new designs due to full voltage range compatibility (2.7V ~ 5.5V) matching the original specification, active product status, and superior moisture sensitivity rating.

Q: Do all substitute parts support the same fault protection mechanisms?

A: Yes. All three substitute parts implement identical fault protection: current limiting (fixed), over-temperature protection, reverse current blocking, and UVLO (under-voltage lockout), matching the original AP2805AMMTR-G1 architecture.
