optimized for Universal Serial Bus (USB) and other hot-swap
applications. The family of devices complies with USB 2.0 and
available with both polarities of Enable input.
They offer current
and thermal limiting and short circuit protection as well as
controlled rise time and under-voltage lockout functionality. A 7ms
deglitch capability on the open-drain Flag output prevents false
over-current
reporting
and
does
not
require
any
external
components.
All devices are available in SOP-8L and MSOP-8L-EP packages.
Consumer electronics – LCD TV & Monitor, Game Machines
