MAX20328A

MAX20328/MAX20328A MUX Switch for USB Type-C Audio Adapter Accessories General Description The MAX20328/MAX20328A are USB Type-C audio interface ICs for use in portable devices. As USB Type-C and USB power delivery (PD) make a high-voltage charging solution readily available, the data and SBU lines are at risk of shorting to a high bus voltage, risking permanent damage to the portable device. USB 2.0 data lines also need protection when multiplexed with analog audio signals that vary from positive to negative voltages. The devices can detect a CC pin connection event to disable the microphone bias and eliminate pop up noise when an audio accessory is attached. The MAX20328/MAX20328A come in a 5 x 5 array, 25-bump, 0.4mm pitch, 2.34mm x 2.34mm wafer-level package (WLP).
