MAX20328, MAX20328A, MAX20328B

MUX Switch for USB Type-C Audio Adapter Accessories

OVP and Surge Protected Audio Accessory Switch for USB Type-C


Please check latest availability status for a specific part variant.

Description

The MAX20328/MAX20328A/MAX20328B 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/MAX20328B come in a 5 x 5 array, 25-bump, 0.4mm pitch, 2.31mm x 2.31mm wafer-level package (WLP).
