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).
Features
• Supply Voltage: 1.6 V to 2.75 V • Low Quiescent Supply Current: 7.5 mA typical @ VDD = 1.
