MAX20328/MAX20328A/ MUX Switch for USB Type-C MAX20328B Audio Adapter Accessories General Description Benefits and Features The MAX20328/MAX20328A/MAX20328B are USB Type-C Versatile and Flexible Switch Configurations audio interface ICs for use in portable devices. As USB High-Speed USB Data or Audio Switch Paths Type-C and USB power delivery (PD) make a high-volt- Automatic Impedance Detection in Audio age charging solution readily available, the data and SBU Configurations lines are at risk of shorting to a high bus voltage, risking Full Manual Switch Control permanent damage to the portable device. USB 2.0 data Beyond-the-Rails Signal Capability lines also need protection when multiplexed with analog Overvoltage Protected Data and Audio Channels audio signals that vary from positive to negative voltages. Two Separate OVLO Blocks The devices can detect a CC pin connection event to OVLO Threshold Programmable to 3.37V, 4.00V, disable the microphone bias and eliminate pop up noise 4.70V, or 5.00V when an audio accessory is attached. Negative Voltage Capable Audio Channel The MAX20328/MAX20328A/MAX20328B come in a 5 x 5V Audio Signals (Limited by Positive OVLO 5 array, 25-bump, 0.4mm pitch, 2.31mm x 2.31mm wafer- Threshold) level package (WLP). -100dB THD+N Applications -100dB PSRR at 217Hz Smart Phones High ESD and Surge-Protected USB Type-C Contacts Phablets 12kV HBM Tablet PCs 25V Surge Capable on USB Type-C Pins Minimal Solution size 5 x 5 Array, 0.4mm Pitch 2.31mm x 2.31mm WLP Ordering Information appears at end of data sheet.
