Why Buy Four Chips if You Only Need One?

Azoteq recently expanded its offering to the TWS market with the release of the IQS323. The IQS323 offers capacitive and inductive sensing as user interface and in-ear-detection, whilst the IQS7222A IC is a multifunctional capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking. The IQS7222A is offered in a 1.62 x 1.62mm WLCSP and allows you to add a touch-and-swipe interface, wear detection, docking detection and your choice of an inductive waterproof button or the inductive force-sensing features.
