MAX20328AEWA+

MAX20328AEWA+ is an USB Type-C audio interface IC for use in portable devices. As USB Type-C and USB power delivery (PD) makes 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 analogue 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. It is used in applications such as smart phones, phablets, tablet PCs.
