The MAX20328B is a Maxim (Analog Devices) USB Type-C audio interface and protection IC used in smartphone and tablet charging port circuits. It routes signals between the USB data path and the analog audio path, while protecting the DP/DM and SBU lines from high-voltage PD surges. Built in a compact 25-bump WLP package, it handles automatic microphone and ground orientation detection for USB-C audio accessories, pop-noise suppression, and programmable overvoltage lockout. Pin-to-pin and register compatible with MAX20328 and MAX20328A, it's a direct board-level replacement for dead USB-C port, audio switching, or surge-damage repairs on affected devices, and a standard part in professional GSM repair inventories.
