AP21410 / AP21510
0.2A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP21410 and AP21510 are integrated high-side power switches
optimized for Universal Serial Bus (USB) and other hot-swap
applications. The family of devices complies with USB 2.0 and is
available with both polarities of Enable input. They offer current and
thermal limiting and short circuit protection as well as controlled rise
time and undervoltage lockout functionality.
All devices are available in U-DFN2018-6 packages.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling
and transporting these devices.
4. UL Recognized Rating from -30°C to +70°C (Diodes qualified T
ST
from -65°C to +150°C).
5. External capacitors need to be connected to the output, EVM board was tested with capacitor 2.2μF 50V 0805.
This level is a pass test only and not a limit.
