*) The AC Voltage on Coil is limited by the on chip voltage
limitation circuitry. This is according to the parameter Icoil
in the absolute maximum ratings.

Absolute Maximum Ratings
Maximum DC Current forced on COIL1 & COIL2 ICOIL ±30mA
Power Supply VDD -0.3 to 7.5V

AC Voltage on Coil Min 3 Typ 14. Vpk-pk

L: typical 20.8mH for fo = 125kHz

Hmmmm.......... 125kHz is below the frequency where mandatory EMC specs apply
(150kHz).

I suspect you could build and sell a legal 'zapper'.
