The ACP1252 is a current limit power switch designed for
load-switching applications. The current limit threshold be set
at an accurate 2.1A. The integrated current-limiting circuit
protects the input supply against large currents which may
cause the supply to fall out of regulation. They offer current
and thermal limiting and short circuit protection as well as
controlled rise time and under-voltage lockout functionality. A
8ms deglitch capability on the open-drain Flag output prevents
false over-current reporting and does not require any external
components.
