AP2822CKBTR-G1 Equivalent & Substitute Parts

Part Overview

The AP2822CKBTR-G1 is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB power switching applications. This N-Channel high-side switch operates at 1A maximum output current with an RDS(on) of 85mOhm typical. The part is classified as Obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. Substitute parts must maintain functional equivalence across critical electrical parameters including output configuration, current rating, voltage specifications, and fault protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the AP2822CKBTR-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
• Voltage - Load: 2.7V ~ 5.5V operating range
• Current - Output (Max): 1A maximum output current capability
• Output Configuration: High Side switching topology
• Operating Temperature: -40°C ~ 85°C range
• Fault Protection: Current Limiting (Fixed), Over Temperature, Reverse Current, UVLO
• RoHS Compliance: ROHS3 Compliant status

The AP22816AKBWT-7 qualifies as a substitute despite output channel type difference (P-Channel vs N-Channel) because it maintains all critical functional parameters: identical 1A current rating, matching voltage specifications, equivalent high-side configuration, and superior RDS(on) performance (75mOhm vs 85mOhm). Both parts serve identical USB power switch applications with compatible fault protection architectures.

Parameter Comparison

Engineering Selection Recommendations

The AP22816AKBWT-7 is the designated substitute for the obsolete AP2822CKBTR-G1. Selection is justified on the following basis:

• Product Status: AP22816AKBWT-7 maintains Active status, ensuring continued availability and manufacturing support, whereas AP2822CKBTR-G1 is Obsolete.
• Compliance: Both parts maintain ROHS3 Compliant and REACH Unaffected status, meeting regulatory requirements.
• Automotive Qualification: AP22816AKBWT-7 carries AEC-Q100 qualification and Automotive grade designation, providing enhanced reliability assurance.
• Electrical Equivalence: Matching voltage range (2.7V ~ 5.5V), current rating (1A), and operating temperature (-40°C ~ 85°C) ensure direct functional replacement.
• Enhanced Protection: AP22816AKBWT-7 includes Short Circuit protection in addition to the fault protection features present in AP2822CKBTR-G1.
• Improved Performance: RDS(on) of 75mOhm in AP22816AKBWT-7 represents 11.8% reduction compared to 85mOhm in AP2822CKBTR-G1, resulting in lower power dissipation.

Frequently Asked Questions (FAQ)

Q: Can AP22816AKBWT-7 directly replace AP2822CKBTR-G1 in existing designs?

A: Yes. Both parts maintain identical voltage specifications (2.7V ~ 5.5V), current rating (1A), output configuration (high side), and operating temperature range (-40°C ~ 85°C). The primary design consideration is output channel type: AP2822CKBTR-G1 uses N-Channel topology while AP22816AKBWT-7 uses P-Channel topology. Circuit topology must accommodate this difference; however, both configurations serve equivalent USB power switch applications.

Q: What is the difference in RDS(on) between these parts?

A: AP2822CKBTR-G1 specifies 85mOhm typical RDS(on), while AP22816AKBWT-7 specifies 75mOhm typical RDS(on). The lower RDS(on) in AP22816AKBWT-7 reduces on-state power dissipation and improves thermal performance.

Q: Are there packaging differences between these parts?

A: AP2822CKBTR-G1 is supplied in Cut Tape (CT) & Digi-Reel® packaging with SC-74A/SOT-753 case. AP22816AKBWT-7 is supplied in Tape & Reel (TR) packaging with SOT-23-5 Thin/TSOT-23-5 case. Both are surface mount packages with compatible footprints for SOT-23-5 applications.

Q: What additional fault protection does AP22816AKBWT-7 provide?

A: AP22816AKBWT-7 includes Short Circuit protection in addition to Current Limiting (Fixed), Over Temperature, Reverse Current, and UVLO protection features present in AP2822CKBTR-G1.

Q: Why is AP2822CKBTR-G1 classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production. AP22816AKBWT-7 maintains Active status and is the recommended substitute for ongoing production and design support.

Q: Does AP22816AKBWT-7 meet automotive standards?

A: Yes. AP22816AKBWT-7 carries AEC-Q100 qualification and Automotive grade designation, providing enhanced reliability assurance for automotive applications.
