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.
