The MAX20317 is an I2C controllable, universal 3.5mmØ accessory management IC. The device provides a universal jack interface solution, as well as a compact solution for the power management and interface control of a powered accessory, such as an active noise cancelling (ANC) headset. The MAX20317 automatically measures headset impedance with a high precision, triple current source 8 bit ADC. After impedance detection, the device also detects when a headset is in a CTIA or OMTP configuration and automatically configures the SLEEVE and RING2 terminals to correctly connect the microphone and ground lines. When a boost supply is applied, the MAX20317 can detect the presence of an ANC headset. When the ANC headset is detected and enabled, a button-press monitoring circuit activates and flags button presses by detecting the voltage drop across a sense resistor. The MAX20317 provides a power line communication tool to a headset to exchange the data with the host device. The MAX20317 has the two separate ground sense inputs from the SLEEVE and RING2 terminals of the connector to provide a high ground isolation to the audio codec. The MAX20317 is available in a space-saving, 20-bump, 0.4mm pitch, 1.65mm x 2.05mm wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
