Description
The AP2337 is single channel current-limited integrated high-
side power switches optimized for hot-swap applications. The
devices have fast short-circuit response time for improved
overall system robustness and provide a complete protection
solution for application subject to heavy capacitive loads and
the prospect of short circuit. It offers reverse current blocking,
over-current, over-temperature and short-circuit protection,
as well as controlled rise time and under-voltage lockout
functionality.
The device is available in SOT23 package.

Notes: 3. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
4. During output over-voltage protection, the output draws approximately 60µA current.
5. Since the output turn-on slew rate is dependent on input supply slew rate, this limit is only applicable for input supply slew rate between 5V/0.2ms to
5V/1ms.
6. Device mounted on FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.
7. Applicable for output voltage slew rate ≤ 5V/30μs.
