1.5A High-side Power Distribution Switch with Enable and Flag
AP2815
General Description
The AP2815 is an integrated high-side power switch
that consists of N-Channel MOSFET, charge pump,
over current & temperature and other related protection
circuits. The switch’s low R
DS(ON)
, 60mΩ, is designed
to meet the USB voltage drop requirements. The IC
integrates soft-start to limit inrush current,
over-current protection, load short protection with
fold-back, and thermal shutdown to avoid switch
failure during hot plug-in. Under voltage lockout
(UVLO) function is used to ensure the device
remains off unless there is a valid input voltage
present. A FLAG output is available to indicate fault
conditions to the local USB controller.
The AP2815 is available in standard packages of
SOIC-8 and MSOP-8.
