Diodes AP24X1S-13 2.0a single channel current-limited power switch with latch-off Datasheet

AP2401/AP2411
2.0A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH LATCH-OFF
Description
Pin Assignments
NEW PRODUCT
The AP2401 and AP2411 are single 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 is available with
both polarities of Enable input.
(Top View)
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 applications 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.
AP2401 and AP2411 will be latched off after 7ms deglitch.
All devices are available
DFN3030-8 packages.

POWER SWITCH WITH LATCH-OFF
Application Notes
NEW PRODUCT
Power Supply Considerations
A 0.1μF to 2.2μF X7R or X5R ceramic bypass capacitor
placed between IN and GND, close to the device, is
recommended. When an external power supply is used,
or an additional ferrite bead is added to the input, high
inrush current may cause voltage spikes higher than the
device maximum input rating during short circuit condition.
In this case a 2.2μF or bigger capacitor 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 0.1μF to 1.0μF
ceramic capacitor improves the immunity of the device to
short circuit transients.
When that happens, the FLG will remain low and the
switch will be latched off until the fault condition is
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 AP2401/AP2411 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:
Over-current 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
devices will limit the current until the overload condition is
removed or the internal deglitch time (7-ms typical) is
reached and the device is turned off. The device will
remain latched off even overload condition is removed
until power is cycled or the device enable is toggled.
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
AP2401/AP2411 senses the short circuit and immediately
clamps output current to a certain safe level namely
ILIMIT, and turns off after deglitch time(7-ms typical).
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
current for deglitch time period (7-ms typical), and then
turned off.
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 AP2401/AP2411 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 output current is clamped at ILIMIT for deglitch
time period (7-ms typical), and then turned off.
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.
AP2401/AP2411
Document number: DS35113 Rev. 3 - 2
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 AP2401/AP2411
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
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 occurs with 7-ms deglitch.
When the FLG is asserted, the switch will be latched off
until the temperature drops to 20°C below the thermal
shutdown threshold and the power or EN pin is cycled.
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.
