fault indication output.
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. When VOUT drops below 1.5V, the devices limit
the current to a lower and safe level. The OTP limits the
junction temperature below 140oC in case of short circuit
or over load conditions.

Function Description
VIN Under-Voltage Lockout (UVLO)

Pull the ENB above 2V or EN below 0.8V to disable the
device, and pull ENB pin below 0.8V or EN above 2V to

UVLO circuit has hysteresis and a de-glitch feature so
current is reduced to less than 1µA. The enable input is

current.
Over-Temperature Protection

protection is designed to protect the IC in the event of
Current-Limit Protection
over temperature conditions. For normal operation, the
junction temperature cannot exceed TJ=+125oC.
The APL3516A/B/C/D 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 the over load or 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 condition. If the junction temperature is
over the thermal shutdown temperature, the device will
enter the thermal shutdown.
OCB Output
The APL3516A/B/C/D series of power switches provide
an open-drain 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 OCB goes low.
Since the OCB pin is an open-drain output, connecting a
resistor to a pull high voltage is necessary.

Application Information
Input Capacitor
A 1µF ceramic bypass capacitor from VIN to GND, located
near the APL3516, 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 damage internal control circuitry.
Output Capacitor
A low-ESR 150µF aluminum electrolytic or tantalum between VOUT and GND is strongly recommended to reduce the voltage droop during hot-attachment of downstream peripheral. Higher-value output capacitor is better
when the output load is heavy. Additionally, bypassing the
output with a 0.1µF ceramic capacitor improves the immunity of the device to short-circuit transients.
Layout Consideration
The PCB layout should be carefully performed to maximize 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 highfrequency ripples.
3. Locate APL3516 and output capacitors near the load to
reduce parasitic resistance and inductance for excellent
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.
