BQ4050: Input not connected => PRES/SHDN and DISP

Part Number: BQ4050
Other Parts Discussed in Thread: BQ40Z50

Hello,

On our design we have 2 input not connected, PRES/SHDN and DISP.

It is recommended by the technical documentation, in order to protect the component against ESD, to install on the PRES input (8.2.2.2.3) :

• At least one resistance (R29) ;
• At most one resistance and one Zener diode (R29 and D4) ;

Furthermore, regarding the DISP input, knowing that we are not using the LEDCNTL outputs, should we connect this input to Vss (8.2.2.3.5) ?

To recap, what are the risks to the component if we leave these two input floating.

Many thanks !

Regards.
