Use case

Improve accuracy of face recognition for smartphone or in-cabin gesture recognition

For applications using light sensing technology, resin sealed MOSFET which is high inductance may cause switching waveform ringing, eventually cause decrease on accuracy of distance measurement or object recognition. In case of CSP MOSFET, the ultra low inductance helps to achieve higher accuracy.
