AEC-Q100 USB protection for 12V and 24V automotive buses
The Texas Instruments TPS25830QWRHBRQ1 is an automotive-grade USB protection IC from the TPS25830 family, qualified to AEC-Q100 for deployment in vehicle electrical systems. It integrates a USB power switch with overcurrent and overvoltage protection, sized for the 4.5V to 36V supply range that covers both 12V and 24V automotive architectures, including load-dump transients up to the 36V absolute maximum. The 700µA quiescent supply current suits always-on modules — infotainment head units, telematics control units, or USB charging ports that must not drain the battery in key-off mode.
Package and mounting — wettable flank for AOI
Housed in a 32-VFQFN Exposed Pad package (5x5 mm body, supplier device package 32-VQFN), the TPS25830QWRHBRQ1 uses a wettable flank terminal finish. This allows automated optical inspection (AOI) of the solder joints after reflow — a requirement for automotive production lines that cannot rely on X-ray alone to verify QFN side-wetting.
No official successor or second-source alternate is listed — the base product number TPS25830 covers the family, and the QWRHBRQ1 suffix denotes the automotive-qualified, wettable-flank variant in the 32-VQFN package.
