Implementing a driven shield
on STM8T and STM8TS capacitive sensors

Introduction
The STM8T and STM8TS capacitive sensors opens up a new dimension to capacitive
sensing by detecting user’s proximity up to 30 cm. This is a key feature for many end-
applications such as personal navigation devices (PNDs) or stove tops which are equipped
with backlighting that switches on when a user is detected. Proximity detectors are also
implemented in white goods, automotive devices, palm tops, an
