High-Side Power Protection Switches

The protection features include current-limit protection,

short-circuit protection, and over-temperature protection.

The device limits the output current at current limit thresh-

old level. When V

the current to a lower and safe level. The over-tempera-

ture protection limits the junction temperature below

Other features include a deglitched OCB output to indi-

cate the fault condition and an enable input to enable or

disable the device.
