optimized for Universal Serial Bus (USB) and other hot-swap
applications. The UTC US212 complies with USB 2.0. Both
polarities of Enable input are available. The UTC US212 offers
current and thermal limiting and short circuit protection, as well as
controlled rise time and under-voltage lockout functionality. The
open-drain Flag output with a pull-up resistance to IN have a
blanking time, 7ms typically, for preventing false over-current
reporting, and does not require any external components.
