PI5PD2068UEE Equivalent & Substitute Parts

Part Overview

The PI5PD2068UEE is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 input-to-output configuration and high-side N-channel output. This component operates at 2.1A maximum output current with 70mOhm typical on-resistance and integrates comprehensive fault protection including current limiting, over-temperature, reverse current, and UVLO monitoring. The device is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5PD2068UEE is constrained by the following critical parameters:

Primary Substitution Criteria:

• Switch Type: USB Switch or General Purpose Power Switch
• Output Configuration: High Side N-Channel
• Package Compatibility: 8-TSSOP or 8-MSOP form factor
• Voltage Range: 2.7V ~ 5.5V load voltage support
• Fault Protection: Current Limiting, Over Temperature, UVLO minimum
• Operating Temperature: -40°C ~ 105°C capability

Substitute Classification:

The TPS2066TDGNRQ1 (Texas Instruments) qualifies as a functional substitute despite differing in output count (1:2 vs. 1:1) and maximum current (1A vs. 2.1A). This device maintains identical voltage specifications, package form factor, on-resistance, fault protection architecture, and operating temperature range. The reduced output current and increased output count represent design trade-offs acceptable in applications where the 1A per-output specification meets load requirements.

The BQ26200PW, BQ26200PWR, BQ26220PW, BQ26220PWR, and BQ26221PW devices are listed in the original substitute field but function as battery monitor ICs rather than power switches. These components do not meet the core functional requirements of the PI5PD2068UEE and are not valid substitutes for power switching applications.

Parameter Comparison

Engineering Selection Recommendations

The TPS2066TDGNRQ1 is the only valid functional substitute for the PI5PD2068UEE among the listed alternatives. Selection of this substitute is supported by:

Compliance & Status: The TPS2066TDGNRQ1 maintains active product status with full manufacturer support, addressing the obsolescence of the PI5PD2068UEE. Both devices carry ROHS3 compliance and equivalent environmental certifications (REACH Unaffected, EAR99 classification).

Electrical Compatibility: Identical voltage specifications (2.7V ~ 5.5V), on-resistance (70mOhm typical), and operating temperature range (-40°C ~ 105°C) ensure direct functional compatibility in existing circuit topologies. The TPS2066TDGNRQ1 incorporates AEC-Q100 automotive qualification, providing enhanced reliability assurance.

Design Considerations: The TPS2066TDGNRQ1 provides 1A per output across two independent channels versus the PI5PD2068UEE's single 2.1A output. Applications requiring full 2.1A on a single output require current-summing techniques or alternative component selection. The TPS2066TDGNRQ1's dual-output architecture and status flag feature enable enhanced system monitoring capabilities.

Package Compatibility: Both devices utilize identical 8-TSSOP/8-MSOP form factors with exposed pads, permitting direct PCB layout reuse without redesign.

Frequently Asked Questions (FAQ)

Q: Why are the BQ26200 and BQ26220 series not suitable substitutes?

A: These devices are battery monitor ICs with HDQ interface functionality. They do not perform power switching operations and lack the output driver architecture required for USB switch applications. Functional requirements are fundamentally different from the PI5PD2068UEE.

Q: Can the TPS2066TDGNRQ1 replace the PI5PD2068UEE in all applications?

A: The TPS2066TDGNRQ1 is suitable for applications where per-output current requirements do not exceed 1A. Applications requiring the full 2.1A single-output capability of the PI5PD2068UEE require alternative component selection or parallel-output configuration techniques.

Q: Are there package compatibility concerns with the TPS2066TDGNRQ1?

A: No. Both the PI5PD2068UEE and TPS2066TDGNRQ1 utilize 8-TSSOP/8-MSOP packages with identical 0.118" (3.00mm) width and exposed pad configuration. PCB footprints are directly compatible.

Q: What is the impact of the TPS2066TDGNRQ1's dual-output configuration?

A: The 1:2 input-to-output ratio provides two independent high-side switches from a single control input. Applications using only one output channel can leave the second channel unused or employ it for additional switching functions. Pin configuration must be verified against the TPS2066TDGNRQ1 datasheet.

Q: Does the TPS2066TDGNRQ1 provide equivalent fault protection?

A: The TPS2066TDGNRQ1 includes current limiting (fixed), over-temperature, and UVLO protection. The PI5PD2068UEE additionally integrates reverse current protection. Circuit design must account for this difference if reverse current blocking is required.

Q: What is the significance of AEC-Q100 qualification on the TPS2066TDGNRQ1?

A: AEC-Q100 qualification indicates automotive-grade reliability testing and enhanced manufacturing controls. This provides higher assurance for mission-critical applications, though both devices meet standard industrial compliance requirements.
