TPS2228PWPR Equivalent & Substitute Parts

Part Overview

The TPS2228PWPR is a Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments, classified as a Power Switch/Driver with a 3:4 input-to-output ratio and 1A maximum output current. This component is designed for PCMCIA switch applications with high-side output configuration and operates across load voltages of 1.8V, 3.3V, and 5V.

The TPS2228PWPR is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2228PWPR is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Mounting Type: Surface Mount (20-PowerTSSOP package)
• Output Configuration: High Side
• Switch Type: PCMCIA Switch
• Fault Protection: Current Limiting (Fixed) and Over Temperature protection
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Maximum Output Current: 1A
• RoHS3 Compliance

Allowable Variation Parameters:

• Number of Outputs: May differ (3:4 ratio vs. alternative ratios)
• Interface Type: May differ (Serial vs. Parallel)
• Load Voltage Range: May differ (subset or superset of 1.8V, 3.3V, 5V)
• Rds On (Typ): May differ within acceptable performance margins
• Moisture Sensitivity Level: May differ

The TPS2211APWPR qualifies as a substitute based on these criteria, despite differences in output count (2 vs. 4), input-to-output ratio (3:2 vs. 3:4), interface type (Parallel vs. Serial), and load voltage support (3.3V, 5V, 12V vs. 1.8V, 3.3V, 5V).

Parameter Comparison

Engineering Selection Recommendations

The TPS2211APWPR is the manufacturer-recommended substitute for the obsolete TPS2228PWPR. Both components share identical core electrical characteristics: 1A maximum output current, high-side output configuration, PCMCIA switch functionality, identical operating temperature range, and equivalent fault protection mechanisms.

Both parts maintain ROHS3 compliance and are manufactured by Texas Instruments using the same 20-PowerTSSOP package footprint, ensuring mechanical compatibility in existing PCB designs.

The primary distinction is product status: the TPS2228PWPR is obsolete, while the TPS2211APWPR is active and available in production quantities. The TPS2211APWPR demonstrates improved on-resistance performance (70mOhm vs. 97mOhm), resulting in lower power dissipation and enhanced thermal efficiency.

Design integration of the TPS2211APWPR requires evaluation of the following differences: reduced output count (2 vs. 4), modified input-to-output ratio (3:2 vs. 3:4), parallel interface operation (vs. serial), and extended load voltage support (12V addition). These variations necessitate circuit-level assessment to confirm functional equivalence within the target application.

Frequently Asked Questions (FAQ)

Q: Can the TPS2211APWPR directly replace the TPS2228PWPR without PCB modifications?

A: Both components use the 20-PowerTSSOP package with identical footprint dimensions (0.173", 4.40mm width), enabling direct physical placement. However, functional substitution requires evaluation of interface differences (serial vs. parallel control), output count requirements (4 vs. 2), and load voltage specifications before confirming electrical compatibility.

Q: What are the key differences between these two parts?

A: The TPS2228PWPR provides 4 outputs with 3:4 input-to-output ratio and serial interface control. The TPS2211APWPR provides 2 outputs with 3:2 input-to-output ratio and parallel interface control. The TPS2211APWPR supports 12V load voltage, while the TPS2228PWPR supports 1.8V. Both maintain identical maximum output current (1A), operating temperature range (-40°C to 85°C), and fault protection features.

Q: Does the improved Rds On specification of the TPS2211APWPR affect circuit design?

A: The TPS2211APWPR exhibits lower on-resistance (70mOhm vs. 97mOhm), resulting in reduced power dissipation and improved thermal performance. This represents a performance improvement that does not negatively impact existing designs but may allow for reduced thermal management requirements.

Q: Are both parts RoHS compliant?

A: Both the TPS2228PWPR and TPS2211APWPR are ROHS3 compliant. The TPS2211APWPR carries MSL Level 2 (1 Year) moisture sensitivity, while the TPS2228PWPR carries MSL Level 1 (Unlimited). Both are REACH unaffected and classified under ECCN EAR99.

Q: What is the availability status of these components?

A: The TPS2228PWPR is obsolete with 762 pieces available in existing inventory. The TPS2211APWPR is active with 3,275 pieces available in production stock, packaged in Tape & Reel format for manufacturing environments.
