switching and other power management applications,
including Advanced Configuration and Power Interface
(ACPI). The MIC2544/48 are cost-effective, highly
integrated solutions that require few external
components to satisfy USB and ACPI requirements.

•
Load current management features include a precision
resistor-programmable output current-limit and a
soft-start circuit that minimizes inrush current when the
switch is enabled. Thermal shutdown, along with
current-limit, protects the switch and the attached
device.
The MIC2544/48’s open-drain flag output is used to
indicate current-limiting or thermal shutdown to a local
controller. The MIC2548 has an additional internal latch
that turns the output off upon thermal shutdown,
providing robust fault control. The enable signal is
compatible with both 3V and 5V logic, and is also used
as the thermal shutdown latch reset for the MIC2548.

Note 1:
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

Enable (Input): Logic-compatible enable input. Active-high (-1) or
active-low (-2). High input >1.7V typical; low input VIN)
when the switch is disabled. In this situation, the
MIC2544/48 avoids undesirable current flow from OUT
to IN. Both OUT pins must be connected together.
5.2
Thermal Shutdown
Thermal shutdown shuts off the output MOSFET and
signals the fault flag if the die temperature exceeds
+140°C. 10°C of hysteresis prevents the switch from
turning on until the die temperature drops to +130°C.
Overtemperature detection functions only when the
switch is enabled.
The MIC2548 features an internal latch which causes
the part to remain off after thermal shutdown until a
reset pulse is provided via the enable pin (pin 1). While
in current-limit, the thermal shutdown latch prevents
on/off cycling of the output.
Refer to Figure 4-4 and Figure 4-5 for timing diagrams.
The flag remains low until reset.
5.3
EQUATION 5-1:
230V
R SET = --------------I LIMIT
Where:
154Ω < RSET < 2.29 kΩ
For example, to set a 1A nominal current-limit, RSET is
calculated as:
EQUATION 5-2:
230V
------------- = 230
1A
Current through RSET increases with OUT current. The
voltage across RSET could be monitored with a high
impedance comparator to provide an indication of
output current. RSET should be between 154Ω ±0.5%
and 2.29 kΩ ±0.5%.
5.5
Short-Circuit Protection
In the event of a short circuit, the output current will fold
back to approximately 80% of the short-circuit
current-limit.
5.6
Fault Flag
FLG is an N-channel, open-drain MOSFET output. The
fault flag is active (low) for current-limit or thermal
shutdown conditions. The flag output MOSFET is
capable of sinking a 10 mA load to typically 100 mV
above ground.
Enable Input
EN must be driven logic high or logic low, or be pulled
high or low for a clearly defined input. Floating the input
may cause unpredictable operation. EN should not be
allowed to go negative with respect to GND, and VEN
should be less than or equal to VIN.
5.4
Adjustable Current-Limit
The short-circuit current-limit is user-adjustable with an
external set resistor. Current-limit in the range of
100 mA to 1.5A is available with a set point accuracy of
better than ±20%. The current-limit circuit prevents
damage to the output MOSFET and external load.
The nominal current-limit value is set with an external
resistor between ILIM and GND. For a desired
current-limit, the value of the external set resistor is
given by:

APPLICATION INFORMATION
6.1
Supply Filtering
A 0.1 μF to 1 μF bypass capacitor from IN to GND,
located near the MIC2544 and MIC2548, is strongly
recommended to control supply transients. Without a
bypass capacitor, an output short may cause sufficient
ringing on the input (from supply lead inductance) to
damage internal control circuitry.
Input transients must not exceed the absolute
maximum supply voltage (VIN(ABS_MAX) = 7V) even for
a short duration.
6.3
Transient Overcurrent Filter
The inrush current from the connection of a heavy
capacitive load may cause the fault flag to fall for 10 μs
to 200 μs while the switch is in a constant-current
mode, charging the capacitance.
Adding an optional series resistor-capacitor (RSET2) in
parallel with RSET, as shown in Figure 6-2, allows the
transient current-limit to be set to a different value than
steady state. A typical USB hot-plug inrush is 2A to 3A
for 10 μs to 20 μs. If RSET is 435Ω (510 mA), an RSET2
of 88Ω (2.5A) and CSET of 1 μF (RC = 100 μs) allows
transient surge of 3A to pass for 100 μs without tripping
the overcurrent flag (FLG).
6.4
USB Power Distribution
The MIC2544 is ideal for meeting USB power
distribution requirements. Figure 6-2 depicts a USB
Host application. RSET should be set to a value
providing a current-limit greater than 500 mA.
MIC2548-1YM
The accurate current-limit of the MIC2544 will reduce
power supply current requirements. Also, fast reaction
to short-circuit faults prevent voltage droop in mobile
PC applications.

FIGURE 6-1:

Supply Bypassing.
Power Dissipation
The device's junction temperature depends on several
factors such as the load, PCB layout, ambient
temperature, and package type. Equations that can be
used to calculate power dissipation and junction
temperature are found below.
Calculation of power dissipation can be accomplished
by the following equation:
Printed Circuit Board Hot-Plug
The MIC2544/48 are ideal inrush current-limiters
suitable for hot-plug applications. Due to the integrated
charge pump, the MIC2544/48 presents a high
impedance when off and slowly becomes a low
impedance as it turns on.
This soft-start feature effectively isolates power
supplies from highly capacitive loads by reducing
inrush current during hot-plug events. Figure 6-3
shows how the MIC2544 may be used in a hot-plug
application.
EQUATION 6-1:
PD = R DS ON I OUT

To relate this to junction temperature, use the following
