Data Sheet
500mA High-side Power Distribution Switch with Enable and Flag
AP2805
General Description
The AP2805 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 RDS (ON), 60mΩ, design
easily to meet USB voltage drop requirements. It
includes 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 remain off unless there is a
valid input voltage present. A Flag output is available
to indicate fault conditions to the local USB
controller.
The AP2805 is available in standard packages of
SOIC-8 and MSOP-8.
