APL3520A/B/C/D
USB Dual Power-Distribution Switches
Features
General Description
•
70mΩ High Side MOSFET
•
Continuous Current
The APL3520 series of power switches are designed for
USB applications. The 70mΩ N-channel MOSFET power
switch satisfies the voltage drop requirements of USB
specification.
-APL3520A/B: 1.5A
-APL3520C/D: 1A
•
Wide Supply Voltage Range: 2.7V to 5.5V
•
Current Limit and Short-Circuit Protections
•
Over-Temperature Protection
•
Deglitched Fault Indication Output
•
Logic Level Enable Input
•
Lead Free and Green Devices Available
The protection features include current-limit protection,
short circuit protection, and over-temperature protection.
The device limits the output current at current limit threshold level, and when VOUT drops below 1.5V, the devices
limit the current to a lower and safe level. The OTP limits
the junction temperature below 140 oC in case of short
circuit or over load conditions.
Other features include deglitched OCBx output to indi-
(RoHS Compliant)

Note : ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant)and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

OCB2
Fault Indication Pin. This pin goes low when a current limit or an over-temperature condition
is detected in VOUT2 after a 10ms deglitch time.

VOUT2
Output Voltage Pin. The output voltage follows the input voltage. When ENB2 is high or
EN2 is low the output voltage is discharged by an internal resistor.

junction temperature cannot exceed TJ=+125oC.
diode. When IC is off, the MOSFETs prevent current flowing from the VOUTx back to VIN and VIN to VOUTx.
Current-Limit Protection
The APL3520 series of power switches provide the current-limit protection function. During current limit, the devices limit output current at current limit threshold. For
reliable operation, the device should not be operated in
current limit for extended period.
Short-Circuit Protection
When the output voltage drops below 1.5V, which is
caused by an over-load or a short-circuit, the devices limit
the output current down to a safe level. The short-circuit
current limit is used to reduce the power dissipation during short-circuit conditions. If the junction temperature
reaches over-temperature threshold, the device will enter the thermal shutdown.
OCB Output
The APL3520 series of power switches provide an opendrain output to indicate that a fault has occurred. When
any of current limit or over-temperature protection occurs
for a deglitch time of tD(OCB), the OCB1/OCB2 goes low.
Since the OCB1/OCB2 pin is an open-drain output, connecting a resistor to a pull high voltage is necessary.
Enable/Disable
Pull the ENB1/ENB2 above 2V or EN1/EN2 below 0.8V
will disable the device, and pull ENB1/ENB2 pin below
0.8V or EN1/EN2 above 2V will enable the device. When
the IC is disabled, the supply current is reduced to less
