P1-P3P4-P6P7-P9P10-P12
NEW PRODUCT
AP2331
0.2A SINGLE CHANNEL CURRENT-LIMITED LOAD SWITCH
Description
The AP2331 is a single channel current-limited integrated high-
side
power switcher 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, SC59 and U-DFN2020-3 packages.

Notes: 5. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
6. When reverse current triggers at I
ROCP
= 0.20A, the reverse current is continuously clamped at I
ROCP
for 0.7ms deglitch time until MOSFET is turned off.
7. During output over-voltage protection, the output draws approximately 60µA current.
8. 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 V
IN
/0.2ms to
V
IN
/1ms.
9. Device mounted on FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.
