TPS2047ADRG4 Equivalent & Substitute Parts

Part Overview

The TPS2047ADRG4 is a Power Switch/Driver IC from Texas Instruments designed for general-purpose switching applications. It features a 1:1 input-to-output ratio with N-Channel high-side output configuration, rated for 250mA maximum output current across a 2.7V to 5.5V load voltage range. The device is packaged in a 16-SOIC surface-mount package and includes integrated fault protection with current limiting, over-temperature monitoring, and under-voltage lockout (UVLO).

The TPS2047ADRG4 is currently classified as obsolete. Identifying equivalent substitute parts is essential for ongoing design support, production continuity, and component sourcing in applications where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2047ADRG4 is determined by strict alignment of the following critical parameters:

• Package / Case: 16-SOIC form factor (0.154", 3.90mm Width) — ensures mechanical and electrical compatibility with existing PCB layouts
• Output Type & Configuration: N-Channel high-side output with 3 outputs
• Voltage - Load Range: 2.7V ~ 5.5V — defines the operational voltage window
• Current - Output (Max): 250mA — establishes current handling capability
• Rds On (Typ): 80mOhm — determines on-state resistance and power dissipation characteristics
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO — ensures equivalent protection mechanisms
• Operating Temperature: 0°C ~ 85°C (TA) — defines thermal operating range
• Compliance: ROHS3 Compliant, MSL 1 — ensures regulatory and environmental compatibility

The TPS2057ADR qualifies as a parametric equivalent based on these criteria. While the TPS2057ADR supports an extended input-to-output ratio configuration (1:2, 1:1) compared to the TPS2047ADRG4 (1:1 only), all other electrical and mechanical parameters remain aligned, and the device maintains backward compatibility in 1:1 mode operation.

Parameter Comparison

Engineering Selection Recommendations

The TPS2057ADR is the qualified substitute for the obsolete TPS2047ADRG4 based on complete electrical and mechanical parameter alignment. The TPS2057ADR is currently in active production status, ensuring long-term component availability and supply chain continuity.

The TPS2057ADR maintains identical performance characteristics in all critical parameters: package form factor, output configuration, voltage and current ratings, on-state resistance, and fault protection mechanisms. The extended input-to-output ratio capability (1:2, 1:1) of the TPS2057ADR does not introduce incompatibility; the device operates in 1:1 mode when configured for direct substitution.

Both devices carry ROHS3 compliance and MSL 1 ratings, confirming equivalent regulatory and environmental qualification. The TPS2057ADR is available in Tape & Reel packaging format, supporting both prototype and production-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the TPS2057ADR directly replace the TPS2047ADRG4 without circuit modifications?

A: Yes. The TPS2057ADR maintains identical electrical specifications for voltage, current, output configuration, and fault protection. The 16-SOIC package footprint is identical, enabling direct PCB substitution. The extended input-to-output ratio capability does not affect 1:1 mode operation.

Q: What is the difference between the 1:1 and 1:2 input-to-output ratios in the TPS2057ADR?

A: The TPS2057ADR supports both 1:1 and 1:2 ratio configurations through pin-selectable logic. For direct substitution of the TPS2047ADRG4, the device operates in 1:1 mode. The 1:2 capability provides additional flexibility for alternative applications but is not required for equivalent operation.

Q: Are there packaging differences between the TPS2047ADRG4 and TPS2057ADR?

A: Both devices use the 16-SOIC (0.154", 3.90mm Width) surface-mount package. The TPS2047ADRG4 was supplied in standard packaging, while the TPS2057ADR is available in Tape & Reel format. The physical package dimensions and pin configuration are identical.

Q: Why is the TPS2047ADRG4 classified as obsolete?

A: The TPS2047ADRG4 has reached end-of-life status in Texas Instruments' product portfolio. The TPS2057ADR represents the active successor product line, offering equivalent functionality with extended configuration options and ongoing manufacturing support.

Q: Are the RoHS and compliance certifications identical?

A: Yes. Both the TPS2047ADRG4 and TPS2057ADR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry identical REACH and ECCN classifications, confirming equivalent regulatory qualification.

Q: What is the input type difference between these devices?

A: The TPS2047ADRG4 features inverting input logic, while the TPS2057ADR features non-inverting input logic. Circuit design must account for this logic inversion difference during substitution. Verify input signal polarity requirements in the application schematic before implementation.
