TPS2057D Equivalent & Substitute Parts

Part Overview

The TPS2057D is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with N-Channel output configuration. This device operates as a 1:2, 1:1 ratio switch with 250mA maximum output current in a 16-SOIC surface mount package. The TPS2057D is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2057D is determined by the following critical parameters:

Primary Substitution Criteria:

• Package type: 16-SOIC surface mount
• Output type: N-Channel
• Output configuration: High Side
• Maximum output current: 250mA
• Load voltage range: 2.7V ~ 5.5V
• Fault protection features: Current Limiting (Fixed), Over Temperature, UVLO
• RoHS3 compliance

Substitute Categories:

Direct Equivalent (TPS2057AD): Maintains identical electrical specifications including 1:2, 1:1 input:output ratio, 80mOhm Rds On, non-inverting input type, and 16-SOIC packaging. Primary difference is product status (Active vs. Obsolete) and operating temperature range (0°C ~ 85°C vs. -40°C ~ 85°C).

Parametric Equivalent (TPS2047BD, TPS2047D): Share core electrical characteristics including N-Channel output, 250mA maximum current, 2.7V ~ 5.5V load voltage, and identical package. Differences include input:output ratio (1:1 only vs. 1:2, 1:1), inverting input type (vs. non-inverting), and Rds On specification (70mOhm for TPS2047BD vs. 80mOhm for TPS2047D).

Parameter Comparison

Engineering Selection Recommendations

TPS2057AD is the primary substitute for TPS2057D. Both devices share identical electrical specifications and packaging. The TPS2057AD is currently in active production status, ensuring long-term availability and supply chain stability. The operating temperature range difference (0°C ~ 85°C vs. -40°C ~ 85°C) requires evaluation only if designs operate below 0°C. RoHS3 compliance and MSL rating are equivalent.

TPS2047BD and TPS2047D are parametric equivalents suitable only when circuit design accommodates the following differences: input:output ratio limited to 1:1 (no 1:2 option), inverting input logic (vs. non-inverting), and for TPS2047BD, reduced Rds On specification (70mOhm vs. 80mOhm). TPS2047BD maintains active product status; TPS2047D is discontinued at DiGi Electronics. Both support the full -40°C ~ 85°C operating temperature range.

Selection between TPS2057AD and TPS2047 variants depends on circuit requirements for input:output ratio configuration and input logic polarity. All candidates maintain identical load voltage range, maximum output current, fault protection features, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TPS2057AD directly replace TPS2057D without circuit modification?

A: Yes. TPS2057AD is a direct equivalent with identical electrical specifications, package type, and pin configuration. The only difference is product status (Active vs. Obsolete) and operating temperature minimum (0°C vs. -40°C). If your application operates at or above 0°C, no circuit changes are required.

Q: What are the key differences between TPS2057D and TPS2047 variants?

A: The primary differences are input:output ratio and input logic type. TPS2057D supports both 1:2 and 1:1 ratios with non-inverting input logic. TPS2047BD and TPS2047D support only 1:1 ratio with inverting input logic. TPS2047BD also features 70mOhm Rds On compared to 80mOhm in other variants. These differences require circuit redesign if switching between families.

Q: Are all substitute parts available in the same 16-SOIC package?

A: Yes. TPS2057AD, TPS2047BD, and TPS2047D are all supplied in 16-SOIC (0.154", 3.90mm Width) surface mount packages with identical pinout compatibility for mechanical placement.

Q: Which substitute offers the best long-term availability?

A: TPS2057AD and TPS2047BD both maintain Active product status, ensuring continued manufacturing and supply chain support. TPS2047D is discontinued at DiGi Electronics and should be avoided for new designs requiring long-term component availability.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. TPS2057AD, TPS2047BD, and TPS2047D are all ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of TPS2057D.

Q: What operating temperature range should I consider when selecting a substitute?

A: TPS2057D, TPS2047BD, and TPS2047D all operate across -40°C ~ 85°C. TPS2057AD operates across 0°C ~ 85°C. If your application requires operation below 0°C, select TPS2057D, TPS2047BD, or TPS2047D. For applications at or above 0°C, TPS2057AD is acceptable.
