USB DCP controller in a SOT-23 footprint
The TPS2513ADBVT is a dedicated USB charging port controller from Texas Instruments, designed to negotiate charging current with BC1.2-compliant portable devices. It integrates the power switch and control logic into a single SOT-23-6 package, saving board space on multi-port hubs or automotive USB outlets. The 155 µA supply current keeps the quiescent draw low enough for always-on ports where the controller stays powered even when no device is attached.
Temperature grade and package constraints
The SOT-23-6 package limits total power dissipation — at 125°C ambient, the allowable junction-to-ambient thermal rise is tight, so the load current and duty cycle need a quick thermal check if the port is sourcing 2 A continuously.
