• Switch Type: USB Switch
• Output Configuration: High Side, N-Channel
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load: 4.5V ~ 18V
• Current - Output (Max): 2.7A
• Rds On (Typ): 90mOhm
• Features: Slew Rate Controlled, Status Flag
• Fault Protection: Current Limiting (Adjustable), Over Temperature, UVLO
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 16-VQFN Exposed Pad (4x4)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• MSL Rating: 2 (1 Year)

All identified substitute parts maintain identical electrical performance characteristics and physical form factors, ensuring direct interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TPS65281RGVT, TPS65281-1RGVR, and TPS65281RGVR—are active products from Texas Instruments with identical electrical specifications and package configurations. Selection between these parts should be based on inventory availability and procurement lead times. All parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent reliability and environmental performance in production environments. The higher inventory levels of TPS65281-1RGVR (5100 units) and TPS65281RGVR (5895 units) provide greater supply chain flexibility compared to TPS65281RGVT (1084 units).
