Firmware for a Realtek RTS5453H Type-C power delivery controller, labelled BM5336 and carrying CRC32 0x13BB74C3. BM5336 likely identifies the board or device, but the name does not say which. The archive is about 117 KB, somewhat larger than single-image PD dumps, so it may hold more than one file. Use it to reprogram the PD controller flash with a programmer when a USB-C port does not supply or accept power. Compare the checksum and the board markings before flashing, and back up the original first.
