TIC10024-Q1: In which condition does it need external ESD protection circuit?

Part Number: TIC10024-Q1

Hi team, 

In which condition does it need external ESD protection circuit? 

Datasheet "Figure 10-1. Using TIC10024-Q1 to Monitor a Digital Switch in Body Control Module Application" includes external ESD circuit RESD and CESD. But it has internal ESD protection circuit and its EVM does not have external ESD protection...

Regards,
Ochi

  • Ochi-san,

    The implementation of this circuitry is based upon the designer. It is not required for the device to operate.

    Note that the internal ESD protection is based upon these CESD and RESD components (see footnotes (3) and (4) in "ESD Ratings").

    Best,

    Danny
