It is a high-side N-channel switch rated for 3A maximum continuous output over a load voltage range of 4.5V to 6.5V. ## Rds(on) and conduction loss Typical on-resistance is 45mOhm, which at 3A output yields about 135mW conduction loss at 25°C junction — well within the thermal budget of the exposed-pad package when the pad is soldered to a copper plane. ## Fault protection set Integrated fault protection includes adjustable current limiting, over-temperature shutdown, over-voltage lockout, and under-voltage lockout (UVLO). A status flag output reports fault conditions to the system controller. Suitable for under-hood or cabin USB charging ports, infotainment hubs, and body-control modules where the ambient can exceed 85°C.","metaTitle":"TPS254900IRVCRQ1 USB Power Switch, AEC-Q100, 45mOhm, 3A","metaDescription":"Texas Instruments TPS254900IRVCRQ1 automotive USB switch, AEC-Q100 qualified, 45mOhm Rds(on), 3A output, -40°C to 125°C.
