1.0A High-side Power Distribution Switch with Enable and Flag
AP2810
General Description
The AP2810 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 AP2810 is available in standard packages of
SOIC-8 and MSOP-8.

Note 1: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute
Maximum Ratings” for extended periods may affect device reliability.

Typical Application
Note 2: 2.2μF input capacitor is enough in most application cases.
If the VOUT is short to ground frequently during usage, large size input capacitor is necessary, recommend
22μF.
