NCS2300

Headset Detection

Interface

The NCS2300 is a compact and cost effective headset detection

interface IC. It integrates a comparator, OR gate, and N−channel

MOSFET to detect the presence of a stereo headset with a

microphone. Pull−up resistors for the detection pins are internalized.

A built in resistor divider provides the reference voltage for detecting

the left audio channel. The logic low output of the OR gate indicates

the headset has been connected properly. The NCS2300 comes in a

space saving UDFN6 package (1.2 x 1.0 mm).
