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.
