Description
The AP2552/53and AP2552A/53A are single channel precision
adjustable current-limited switches optimized for the applications
require precision current limiting or to provide up to 2.1A of
continuous load current during heavy loads/short circuits. These
devices offer a programmable current-limit threshold between 75mA
and 2.36A (typ) via an external resistor. Current limit accuracy ±6%
can be achieved at high current-limit settings. The rise and fall times
are controlled to minimize current surges during turn on/off.
The devices have fast short-circuit response timefor improved overall
system robustness. They provide a complete protection solution for
applications subject to heavy capacitive loads and the prospect of
short circuit, offering reverse current blocking and limiting, over-
current, over-temperature 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.
AP2552/53 limits the output current to a safe level when the output
current exceeds current-limit threshold.
AP2552A/53A provides latch-off function during over-current or
reverse-voltage conditions.
All devices are available in SOT26 and U-DFN2020-6 packages.

... The AP2552/53 AND AP2552A/53A are integrated high-side power switches optimized for Universal Serial Bus (USB) that requires protection functions. The power switches are equipped with a driver that controls the gate voltage and incorporates slew-rate limitation. This, along with the various protection features and special functions, makes these power switches ideal for hot-swap or hot-plug applications. ...
