The ACP12522 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 12ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. The device are available in SOT25 and U-DFN2018-6 packages.
