What this USB-C controller does on an automotive power rail
The TPS25832QCWRHBRQ1 is a USB Type-C and SDP/CDP charge port controller from Texas Instruments, designed for automotive power ports that need to negotiate charging profiles with connected devices. It accepts a 4.5V to 36V input supply, covering both 12V and 24V automotive systems with margin for load-dump transients, and draws 700µA supply current during operation.
Package and board assembly details
Housed in a 32-VFQFN exposed pad package (5x5 mm, supplier device package 32-VQFN), the wettable flank option aids optical inspection of solder joints after reflow. Surface-mount with wettable flank — the side pads wick solder up the package edge, letting AOI verify fillet formation on the bottom-terminated QFN.
