TPS2011DG4 Equivalent & Substitute Parts

Part Overview

The TPS2011DG4 is a Power Management Integrated Circuit (PMIC) functioning as a high-side N-channel power switch driver with 1:1 input-to-output ratio. This component is designed for general-purpose switching applications requiring load voltage operation between 2.7V and 5.5V with maximum output current of 600mA. The TPS2011DG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2011DG4 is determined by strict equivalence across the following critical parameters:

• Package Type: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Output Configuration: High-side N-channel topology with 1:1 input-to-output ratio
• Voltage Rating: Load voltage range of 2.7V ~ 5.5V
• Current Capacity: Maximum output current of 600mA
• Interface Type: On/Off control with non-inverting input
• Fault Protection: Current limiting and over-temperature protection
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Compliance: ROHS3 compliance and MSL Level 1

The identified substitute parts TPS2011D and TPS2011AD maintain electrical and mechanical compatibility within these parameters while differing in product lifecycle status and specific performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

TPS2011D: This part maintains full electrical and mechanical equivalence to the TPS2011DG4 with identical on-resistance (75mOhm) and fault protection features. However, TPS2011D carries a "Not For New Designs" status, indicating limited long-term availability and support. Selection of this part is appropriate only for legacy system maintenance where design changes are not feasible.

TPS2011AD: This part is the recommended substitute for new applications and ongoing production. It maintains all critical electrical parameters including voltage rating, current capacity, and package form factor. The TPS2011AD features improved on-resistance (33mOhm versus 75mOhm) and includes additional Under-Voltage Lockout (UVLO) protection. The "Active" product status ensures continued availability and manufacturer support. The lower on-resistance provides reduced power dissipation in switching applications.

Frequently Asked Questions (FAQ)

Q: Can TPS2011D and TPS2011AD be used interchangeably with TPS2011DG4?

A: Both parts are electrically and mechanically compatible with TPS2011DG4 within the specified parameter ranges. All three parts share identical package geometry (8-SOIC), voltage ratings (2.7V ~ 5.5V), current capacity (600mA), and operating temperature range (-40°C ~ 125°C). Pin-to-pin compatibility is maintained across all three variants.

Q: What is the significance of the lower on-resistance in TPS2011AD?

A: The TPS2011AD exhibits 33mOhm typical on-resistance compared to 75mOhm in TPS2011DG4 and TPS2011D. This 55% reduction in on-resistance decreases power dissipation during switching operation, resulting in lower junction temperatures and improved thermal performance in current-limited applications.

Q: Does TPS2011AD include additional protection features?

A: TPS2011AD incorporates Under-Voltage Lockout (UVLO) protection in addition to the current limiting and over-temperature protection present in TPS2011DG4 and TPS2011D. UVLO prevents device operation when supply voltage falls below specified thresholds, protecting against undefined behavior in low-voltage conditions.

Q: Why is TPS2011DG4 discontinued?

A: Product discontinuation reflects manufacturer lifecycle management decisions. The TPS2011AD represents the current active offering in this product family, providing enhanced performance characteristics while maintaining backward compatibility.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in 8-SOIC surface-mount packages with identical physical dimensions (0.154" width, 3.90mm). Packaging format differences (tube versus other formats) do not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to all three parts?

A: All three parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (unlimited shelf life). REACH status is unaffected for all variants, and all parts carry EAR99 export classification.
