Figure 10. Typical application shematic
1. If the active shield is not used, The SHLDIN pin must be grounded, SHLDOUT should be left unconnected, and
2. Use COG or NPO or higher grade capacitor.
Figure 11. Possible load configurations
can be removed.
TOUT/POUT
Typical application diagram
The smaller the value of the R
consumption.
Pin TOUT/POUT can directly drive a HV FET (as shown in
any load.
A touch or proximity detection is defined as an actuation (high = logical '1' and 
low = logical '0').
