PI5PD2068UEEX Equivalent & Substitute Parts

Part Overview

The PI5PD2068UEEX is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for N-Channel high-side switching applications with 1:1 input-to-output ratio and 2.1A maximum output current. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates across a 2.7V to 5.5V load voltage range with integrated fault protection including current limiting, over-temperature monitoring, reverse current protection, and under-voltage lockout (UVLO).

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5PD2068UEEX is constrained by the following critical parameters: N-Channel output type, high-side output configuration, 2.7V to 5.5V load voltage range, 8-TSSOP/8-MSOP package compatibility, and fault protection architecture. The substitute parts identified from the provided list represent Texas Instruments components that share compatible packaging and electrical operating ranges. However, functional equivalence must be evaluated against specific application requirements, as the substitute parts exhibit variations in output current capacity, input-to-output ratio, and primary functional classification (battery monitoring versus power switching).

The TPS2066TDGNRQ1 maintains the closest functional alignment as a power switch with N-Channel output, high-side configuration, and identical load voltage range. The BQ26200PW, BQ26200PWR, BQ26220PW, BQ26220PWR, and BQ26221PW are battery monitor ICs with different functional purposes and should be evaluated only if application requirements permit functional substitution beyond power switching.

Parameter Comparison

Engineering Selection Recommendations

For direct functional replacement of the PI5PD2068UEEX in power switching applications, the TPS2066TDGNRQ1 is the primary candidate. Both components share identical load voltage range (2.7V ~ 5.5V), equivalent on-resistance (70mOhm typical), N-Channel high-side output configuration, and compatible 8-TSSOP/8-MSOP packaging. The TPS2066TDGNRQ1 maintains active product status with full ROHS3 compliance and AEC-Q100 automotive qualification. The primary design consideration is the reduced maximum output current (1A versus 2.1A), which requires verification against application load requirements.

The BQ26200PW, BQ26200PWR, BQ26220PW, BQ26220PWR, and BQ26221PW are battery monitor ICs with fundamentally different functional purposes (battery chemistry monitoring and cell counting versus power switching). These components are not direct functional equivalents and should only be considered if application requirements have shifted to battery monitoring functionality. These parts operate within a narrower temperature range (-20°C ~ 70°C) compared to the original specification (-40°C ~ 105°C).

All identified substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the TPS2066TDGNRQ1 directly replace the PI5PD2068UEEX in all applications?

A: The TPS2066TDGNRQ1 provides functional equivalence for power switching applications with compatible voltage range and package. However, the maximum output current is reduced from 2.1A to 1A. Applications requiring the full 2.1A output current capacity require alternative solutions or circuit redesign.

Q: Why are the BQ26200 and BQ26220 series listed as substitutes if they are battery monitors?

A: These components are listed based on the provided substitute list. They are not functional equivalents for power switching applications. They represent different product categories (battery monitoring versus power switching) and should only be considered if application requirements permit functional substitution.

Q: Are there package compatibility concerns between the PI5PD2068UEEX and TPS2066TDGNRQ1?

A: Both components use 8-TSSOP/8-MSOP packaging with 0.118" (3.00mm) width and exposed pad configuration. Pin-to-pin compatibility requires verification against specific pinout documentation, as package designation alone does not guarantee identical pin assignments.

Q: What is the impact of the different moisture sensitivity levels?

A: The PI5PD2068UEEX has MSL 1 (unlimited shelf life), while the TPS2066TDGNRQ1 has MSL 2 (1-year shelf life). This affects storage and handling requirements. Components with MSL 2 require controlled humidity storage and have defined bake-out procedures before reflow soldering.

Q: Does the narrower operating temperature range of the BQ26220 series affect compatibility?

A: The BQ26220 series operates from -20°C to 70°C, compared to the PI5PD2068UEEX range of -40°C to 105°C. Applications requiring operation below -20°C or above 70°C cannot use these components. Additionally, these are battery monitor ICs, not power switches, and are not functionally equivalent.
