Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP2822CKATR-G1 is based on the following critical parameters that define functional equivalence:

• Switch Type: USB Switch application requirement
• Number of Outputs: Single output configuration (1)
• Ratio - Input:Output: 1:1 switching ratio
• Output Configuration: High Side switching topology
• Current - Output (Max): 1A rated output current capacity
• Voltage - Load: 2.7V ~ 5.5V operating range
• Mounting Type: Surface Mount package compatibility
• Fault Protection: Current Limiting, Over Temperature, Reverse Current, UVLO

The identified substitute part AP22816AKAWT-7 maintains functional compatibility across these core parameters. While the substitute features P-Channel output topology (versus N-Channel in the original), it preserves the 1:1 ratio, 1A output current, identical voltage range, and equivalent fault protection mechanisms. The substitute is classified as Active product status with enhanced reliability certifications (AEC-Q100 Automotive qualification).

Engineering Selection Recommendations

The AP22816AKAWT-7 is the designated substitute for the obsolete AP2822CKATR-G1 based on the following engineering criteria:

• Active Product Status: The substitute maintains current manufacturing and support status, ensuring long-term availability and supply chain continuity.
• Compliance Certifications: The substitute holds AEC-Q100 Automotive qualification, providing enhanced reliability assurance for critical applications.
• Functional Equivalence: Both parts maintain identical 1:1 switching ratio, 1A output current capacity, and 2.7V to 5.5V voltage range specifications.
• Improved Performance: The substitute features lower on-resistance (75mOhm versus 85mOhm), reducing power dissipation in switching applications.
• Enhanced Fault Protection: The substitute includes Short Circuit protection in addition to the original part's protection features.
• RoHS3 Compliance: Both parts meet environmental regulatory requirements.

The primary design consideration is the output channel topology change from N-Channel to P-Channel. Circuit topology and gate drive requirements must be evaluated for compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AP2822CKATR-G1?
