2.7A high-side USB switch with adjustable current limit
Typical Rds(on) is 90 mOhm, keeping conduction loss low enough that the 16-VQFN exposed-pad package can dissipate the heat without forced airflow in most designs.
Fault protection set: adjustable current limit, OTP, UVLO
The part integrates three fault protections: an adjustable current limit (set by an external resistor), over-temperature shutdown, and under-voltage lockout (UVLO) on the input supply. A status flag output reports fault conditions to the host controller, and the slew-rate controlled turn-on limits inrush current when a capacitive load is connected.
The base product number TPS65281 covers the family; the -1RGVR suffix denotes the specific reel and package variant.
That industrial temperature range suits it for outdoor telecom gear, factory automation I/O modules, and under-hood automotive USB ports where ambient temperatures can exceed 85°C.
