AP2162/ AP2172  
1A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH  
Description  
Pin Assignments  
The AP2162 and AP2172 are integrated high-side power switches  
optimized for Universal Serial Bus (USB) and other hot-swap  
applications. The family of devices complies with USB 2.0 and  
available with both polarities of Enable input. They offer current and  
thermal limiting and short circuit protection as well as controlled rise  
time and under-voltage lockout functionality. A 7ms deglitch capability  
on the open-drain Flag output prevents false over-current reporting  
and does not require any external components.

Caution:  
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;  
functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied.  
Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.  
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling  
and transporting these devices.

AP2162/ AP2172  
Application Information  
Power Supply Considerations  
A 0.01-μF to 0.1-μF 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 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 0.01-μF to 0.1-μF ceramic capacitor improves the immunity  
of the device to short-circuit transients.  
Over-Current and Short Circuit Protection  
An internal sensing FET is employed to check for over-current 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 AP2162/AP2172 senses the short circuit and immediately clamps output current to a certain safe level namely ILIMIT  
.
In the second condition, an output short or 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 over-current  
trip threshold), the device switches into current limiting mode and the current is clamped at ILIMIT  
.
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 (ITRIG) is reached or until the thermal limit of the device is exceeded. The AP2162/AP2172 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 its current limiting mode  
and is set at ILIMIT  
.
FLG Response  
When an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7-ms  
deglitch timeout. The FLG output remains low until both over-current and over-temperature conditions are removed. Connecting a heavy capacitive  
load to the output of the device can cause a momentary over-current condition, which does not trigger the FLG due to the 7-ms deglitch timeout.  
The AP2162/AP2172 is designed to eliminate false over-current reporting without the need of external components to remove unwanted pulses.  
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  
Thermal Protection  
Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The  
AP2162/AP2172 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 over-current 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. The FLG open-drain output is asserted when an over-temperature shutdown or over-current occurs with 7-ms deglitch.

AP2162/ AP2172  
Application Information (cont.)  
Under-voltage Lockout (UVLO)  
Under-voltage 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.  
Host/Self-Powered HUBs  
Hosts and self-powered hubs (SPH) have a local power supply that powers the embedded functions and the downstream ports (see Figure 2). This  
power supply must provide from 5.25V to 4.75V to the board side of the downstream connection under both full-load and no-load conditions. Hosts  
and SPHs are required to have current-limit protection and must report over-current conditions to the USB controller. Typical SPHs are desktop  
PCs, monitors, printers, and stand-alone hubs.  
Figure 2. Typical Two-Port USB Host / Self-Powered Hub  
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 AP2162/AP2172, 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 AP2162/AP2172 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 AP2162/AP2172 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.
