Description
Pin Assignments
NEW PRODUCT
The AP2142A and AP2152A are dual channel current-limited
integrated high-side power switches optimized for Universal
Serial Bus (USB) and other hot-swap applications. The family
of devices complies with USB standards and available with
both polarities of Enable input.

The devices have fast short-circuit response time for
improved overall system robustness, and have integrated
output discharge function to ensure completely controlled
discharging of the output voltage capacitor. They provide a
complete protection solution for application subject to heavy
capacitive loads and the prospect of short circuit, and offer
reverse current blocking, over-current, over-temperature 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.
All devices are available
DFN3030E-8 packages.

Application Note
Power Supply Considerations
A 0.1μF to 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 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 1μF ceramic capacitor improves the immunity of the device to shortcircuit transients.
NEW PRODUCT
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 AP2142A/AP2152A 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 inrush current may flow for a very short period of time before the current limit function can
react. The input capacitor(s) rapidly discharge through the device, activating current limit circuitry. Protection is
achieved by momentarily opening the P-MOS high-side power switch and then gradually turning it on. 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. The threshold for activating current limiting is 0.7A typical per channel.
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 AP2142A/AP2152A 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 overtemperature 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
AP2142A/AP2152A 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

SWITCH WITH OUTPUT DISCHARGE
Application Note (Continued)
NEW PRODUCT
Thermal Protection
Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for
extended periods of time. The AP2142A/AP2152A 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.
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 2V, even if the switch is enabled. Whenever the input voltage falls below
approximately 2V, 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.
Discharge Function
The discharge function of the device is active when enable is disabled or de-asserted. The discharge function with
the N-MOS power switch implementation is activated and offers a resistive discharge path for the external storage
capacitor. This is designed for discharging any residue of the output voltage when either no external output
resistance or load resistance is present at the output.
Host/Self-Powered HUBs
Hosts and self-powered hubs (SPH) have a local power supply that powers the embedded functions and the
downstream ports. 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.
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 AP2142A/AP2152A, 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
AP2142A/AP2152A 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 AP2142A/AP2152A 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 hotplugging mechanism for any device.
