The ITS42k5D-LD-F is a 2.5Ω dual channel high-side power switch and
optimized for driving all types of resistive, inductive and capacitive loads.

This circuit demonstrates the under voltage lockout protection features of
the ITS42k5D-LD-F. Many other switches provide similar protection features.

With a sweep supply voltage from 0 to 60V and back to 0V the under voltage
lockout protection features are demonstrated. The devices start switching
above the minimum functional supply voltage Vuvon of about 4.5V and
will be shut down if it is below the under voltage lockout Vuvoff of about
3.25V and it restarts if the supply voltage above Vuvoff of 3.25V.
