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).
