IQS622 FOR BT EARPHONESFEATURES – 4 TECHNOLOGIES IN ONE

• 2 capacitive channels – one for UI, one for in-ear detection

• Hall effect sensor – detect docking of earphones & use the function for auto-off

• Active IR – combined with capacitive provides the most robust solution available today.

ADVANTAGES• Can bring auxiliary features to low power mode• Can turn on music when worn, off when removed from

the ear• Robust wear detect solution (capacitive + IR)• No need for ON/OFF button• Power saving

SENSORS• IQS622 – 2 touch channels, Hall effect and IR

• IR + Capacitive provides improved reliability over single sensor technology
