MAX20328/MAX20328A/

MAX20328B

MUX Switch for USB Type-C

Audio Adapter Accessories

General Description

Beneﬁts and Features

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-volt-

age 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.

● Versatile and Flexible Switch Configurations

• High-Speed USB Data or Audio Switch Paths

• Automatic Impedance Detection in Audio

Conﬁgurations

4.70V, or 5.00V

● Negative Voltage Capable Audio Channel

• ±5V Audio Signals (Limited by Positive OVLO

Threshold)

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).
