Application Information
Power Supply Considerations
A 0.01μF to 0.1μF X7R or X5R ceramic bypass capacitor between IN and GND, close to the device, is recommended. Placing a high-value
electrolytic capacitor on the input (10μF minimum) and output pin(s) is recommended when the output load is heavy. This precaution reduces
power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01μF to 0.1μF ceramic capacitor improves
the immunity of the device to short-circuit transients.
Overcurrent and Short Circuit Protection
An internal sensing FET is employed to check for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the series
resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output
voltage accordingly. Complete shutdown occurs only if the fault stays long enough to activate thermal limiting.
Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before VIN
has been applied. The AP21410 / AP21510 short circuit and clamps output current to a certain safe level namely ISHORT.
In the second condition, an overload occurs while the device is enabled. At the instance the overload occurs, higher current may flow for a very
short period of time before the current-limit function can react. After the current limit function has tripped (reached the overcurrent trip threshold),
the device switches into current limiting mode and the current is clamped at I LIMIT.
In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the
current-limit threshold is reached or until the thermal limit of the device is exceeded. The AP21410 / AP21510 is capable of delivering current up to
the current-limit threshold without damaging the device. Once the threshold has been reached, the device switches into overload current limiting
mode and is set at ILIMIT. If the load current keeps going higher, the device will switch into short-circuit current limiting mode and is set at ISHORT.
Note that when the output has been shorted to GND at extremely low temperatures (< -30°C), a minimum 120μF electrolytic capacitor on the output
pin is recommended. A correct capacitor type with capacitor voltage rating and temperature characteristics must be properly chosen so that the
capacitance value does not drop too low at the extremely low temperature operation. A recommended capacitor should have temperature
characteristics of less than 10% variation of capacitance change when operated at extremely low temp. Our recommended aluminum electrolytic
capacitor type is Panasonic FC series.
Power Dissipation and Junction Temperature
The low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating
ambient temperature (TA) and RDS(ON), the power dissipation can be calculated by:
PD = RDS(ON) × I2
Finally, calculate the junction temperature:
TJ = PD x RθJA + TA
Where:
TA = Ambient temperature °C
RθJA = Thermal resistance
PD = Total power dissipation

Application Information (continued)
Thermal Protection
Thermal protection prevents the IC from damage when heavy overload or short-circuit faults are present for extended periods of time. The AP21410
/ AP21510 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature
rises to approximately +140°C due to excessive power dissipation in an overcurrent or short-circuit condition, the internal thermal sense circuitry
turns the power switch off, thus preventing the power switch from damage. Hysteresis is built into the thermal sense circuit allowing the device to
cool down approximately +25°C before the switch turns back on. The switch continues to cycle in this manner until the load fault or input power is
removed.
Undervoltage Lockout (UVLO)
Undervoltage lockout function (UVLO) keeps the internal power switch from being turned on until the power supply has reached at least 1.9V, even
if the switch is enabled. Whenever the input voltage falls below approximately 1.9V, the power switch is quickly turned off. This facilitates the design
of hot-insertion systems where it is not possible to turn off the power switch before input power is removed.
Generic Hot-Plug Applications
In many applications it may be necessary to remove modules or pc boards while the main unit is still operating. These are considered hot-plug
applications. Such implementations require the control of current surges seen by the main power supply and the card being inserted. The most
effective way to control these surges is to limit and slowly ramp the current and voltage being applied to the card, similar to the way in which a
power supply normally turns on. Due to the controlled rise times and fall times of the AP21410 / AP21510, these devices can be used to provide a
softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the AP21410 / AP21510 also ensures that the switch is
off after the card has been removed, and that the switch is off during the next insertion.
By placing the AP21410 / AP21510 between the VCC input and the rest of the circuitry, the input power reaches these devices first after insertion.
The typical rise time of the switch is approximately 1ms, providing a slow voltage ramp at the output of the device. This implementation controls
system surge current and provides a hot-plugging mechanism for any device.
Dual-Purpose Port Applications
AP21410/AP21510 is suitable for use in dual-purpose port applications in which a single port is used for data communication between the host and
peripheral devices while simultaneously maintaining a charge to the battery of the peripheral device. An example of this is a shared HDMI/MHL
(Mobile High-definition Link) port that allows streaming video between an HDTV or set-top box and a smartphone or tablet while maintaining a
charge to the smartphone or tablet battery. In such dual-purpose port applications, it is important to insure Vin of the AP21410/AP21510 is ramped
to its operating voltage prior to enabling the output.
No Output Capacitor Applications
For certain applications, no output capacitor is allowed. It is recommended to add a schottky diode at the output pin to prevent the device damaged
by output accidently short to ground.
Note: All previous Typical Performance Characteristics charts marked CL=0µF have the schottky diode added.
