Headset Detection Interface with Send/End Detect

The NCS2302 is a compact and cost effective headset detection interface IC. It integrates several circuit blocks to detect the presence of a stereo headset with a microphone and whether the send/end button has been pressed. The NMOS transistor on the MIC pin mutes the signal when the headset is not • Wide Supply Voltage for Headset Detection Circuit: VDD = 1.6 V to 2.5 V\n• Wide Supply Voltage for S/E Comparator Circuit: VDD2 = 1.6 V to 2.8 V\n• Low Quiescent Supply Current: 17 µA typical\n• Low Impedance MIC Pull−Down: RDS(ON) = 0.45 Ω Typical\n• Space Saving UQFN10 Package\n• Saves Space on ;
