the overvoltage value (for instance
V = 60V
±
4.2V).
Disable function
The zero current detector (ZCD) pin can be used
for device disabling as well. By grounding the
ZCD voltage the device is disabled reducing the
supply current consumption at 1.4mA typical (@
14.5V supply voltage).
Releasing the ZCD pin the internal start-up timer
will restart the device.
