Product details

Automotive USB power switch — AEC-Q100 qualified

The TPS254900IRVCRQ1 is a Texas Instruments automotive-grade USB power switch, AEC-Q100 qualified, in a 20-WFQFN exposed-pad package. 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.
