• Ratio: 1:1 input-to-output
• Interface: On/Off control with non-inverting input
• Output current capability: Minimum 100mA
• Load voltage range: Must encompass or exceed 1.62V ~ 4.5V
• Package compatibility: Surface mount DSBGA family
• Fault protection: Current limiting and over-temperature protection
• Compliance: ROHS3 and REACH requirements

Identified Substitute Parts:

1. TPS22949AYZPR - Parametric equivalent with identical electrical specifications and package format
2. TPS22950YBHR - Manufacturer-recommended substitute with enhanced performance characteristics

Parameter Comparison

Engineering Selection Recommendations

TPS22949AYZPR serves as a parametric equivalent to the TPS22949YZPR. Both devices share identical electrical specifications, including output current rating (100mA), load voltage range (1.62V ~ 4.5V), on-resistance (300mOhm), and package format (8-DSBGA). Both are classified as obsolete products. This substitute is appropriate for direct replacement in existing designs where the 100mA current capability and specified voltage range are sufficient. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) are maintained.

TPS22950YBHR is the manufacturer-recommended substitute and represents an enhanced alternative. This device maintains the same functional architecture (1:1 P-Channel high-side switch) but offers significant performance improvements: output current capability increased to 2.7A, load voltage range extended to 1.8V ~ 5.5V, and on-resistance reduced to 34mOhm. Fault protection is expanded to include adjustable current limiting, reverse current protection, and short circuit protection. The TPS22950YBHR carries active product status, ensuring long-term availability and support. Operating temperature range extends to 125°C. Package format changes from 8-DSBGA to 6-DSBGA, requiring PCB layout modification. ROHS3 compliance is maintained.

Selection between these substitutes depends on application requirements: use TPS22949AYZPR for pin-compatible replacement with identical performance specifications; use TPS22950YBHR when enhanced current handling, extended voltage range, or improved protection features are beneficial and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can TPS22949AYZPR be used as a direct replacement for TPS22949YZPR?

A: Yes. TPS22949AYZPR is a parametric equivalent with identical electrical specifications, package format, and operating characteristics. No design modifications are required for direct substitution.

Q: What are the key differences between TPS22949YZPR and TPS22950YBHR?

A: The primary differences are output current capability (100mA vs. 2.7A), load voltage range (1.62V~4.5V vs. 1.8V~5.5V), on-resistance (300mOhm vs. 34mOhm), package format (8-DSBGA vs. 6-DSBGA), and fault protection features. TPS22950YBHR offers enhanced performance but requires PCB layout changes due to different package dimensions.

Q: Is TPS22950YBHR compatible with existing PCB layouts designed for TPS22949YZPR?

A: No. The package format differs (6-DSBGA vs. 8-DSBGA), requiring PCB redesign and re-layout. Pin assignments and footprint dimensions are not compatible.

Q: Why is TPS22949YZPR listed as obsolete?

A: Product status reflects manufacturer discontinuation. TPS22949AYZPR and TPS22950YBHR are available alternatives. TPS22950YBHR carries active status, ensuring continued availability.

Q: Are all three parts ROHS3 compliant?

A: Yes. TPS22949YZPR, TPS22949AYZPR, and TPS22950YBHR are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the temperature operating range difference between the main part and substitutes?

A: TPS22949YZPR and TPS22949AYZPR operate from -40°C to 105°C (junction temperature). TPS22950YBHR extends this to -40°C to 125°C (ambient temperature), providing wider thermal operating margin.

Q: Can TPS22950YBHR handle higher current loads than the original part?

A: Yes. TPS22950YBHR is rated for 2.7A maximum output current compared to 100mA for TPS22949YZPR, making it suitable for applications requiring higher current switching capability.
