General Description
The APL3513 is a power-distribution switch with some
protection that can deliver current up to 2A. The device
incorporates a 70mΩ N-channel MOSFET power switch
that is controlled by an enable logic pin.
The protection features include current-limit protection,
short-circuit protection, and over-temperature protection.
The device limits the output current at current limit thresh-
old level. When V drops below V -1V, the devices limit

the current to a lower and safer level. The over-tempera-
ture protection limits the junction temperature below
140oC in case of short circuit or over load conditions.

Application Information
Input Capacitor
A 1µF ceramic bypass capacitor from VIN to GND, located
near the APL3513, is strongly recommended to suppress
the ringing during short circuit fault event. Without the
bypass capacitor, the output short may cause sufficient
ringing on the input (from supply lead inductance) to dam-
age internal control circuitry.
Output Capacitor
A bypassing 0.1µF ceramic capacitor improves the immu-
nity of the device to short-circuit transients. A low-ESR
high capacitance between VOUT and GND is suggested to
reduce the voltage droop during load transient.
Layout Consideration
The PCB layout should be carefully performed to maxi-
mize thermal dissipation and to minimize voltage drop,
droop and EMI. The following guidelines must be
considered:
1. Please place the input capacitors near the VIN pin as
close as possible.
2. Output decoupling capacitors for load must be placed
near the load as close as possible for decoupling high-
frequency ripples.
3. Locate APL3513 and output capacitors near the load to
reduce parasitic resistance and inductance for excel-
lent load transient performance.
4. The negative pins of the input and output capacitors
and the GND pin must be connected to the ground plane
of the load.
5. Keep VIN and VOUT traces as wide and short as possible.
