Single-Channel Power Distribution Switch
Preliminary Information
General Description
Features
The MIC2025 and MIC2075 are high-side MOSFET switches
optimized for general-purpose power distribution requiring
circuit protection.
The MIC2025/75 are internally current limited and have
thermal shutdown that protects the device and load. The
MIC2075 offers “smart” thermal shutdown that reduces current consumption in fault modes. When a thermal shutdown
fault occurs, the output is latched off until the faulty load is
removed. Removing the load or toggling the enable input will
reset the device output.

Both devices employ soft-start circuitry that minimizes inrush
current in applications where highly capacitive loads are
employed. A fault status output flag is provided that is
asserted during overcurrent and thermal shutdown conditions.
The MIC2025/75 is available in the MM8™ 8-lead MSOP and
8-lead SOP.

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 of each channel and junction temperature are
found below.
PD = RDS(on) × IOUT2
Functional Description
Input and Output
IN is the power supply connection to the logic circuitry and the
drain of the output MOSFET. OUT is the source of the output
MOSFET. In a typical circuit, current flows from IN to OUT
toward the load. If VOUT is greater than VIN, current will flow
from OUT to IN since the switch is bidirectional when enabled. The output MOSFET and driver circuitry are also
designed to allow the MOSFET source to be externally forced
to a higher voltage than the drain (VOUT > VIN) when the
switch is disabled. In this situation, the MIC2025/75 avoids
undesirable current flow from OUT to IN.
Thermal Shutdown
Thermal shutdown is employed to protect the device from
damage should the die temperature exceed safe margins
due mainly to short circuit faults. Each channel employs its
own thermal sensor. Thermal shutdown shuts off the output
MOSFET and asserts the FLG output if the die temperature
reaches 140°C. The MIC2025 will automatically reset its
output should the die temperature cool down to 120°C. The
MIC2025 output and FLG signal will continue to cycle on and
off until the device is disabled or the fault is removed. Figure
2 depicts typical timing. If the MIC2075 goes into thermal
shutdown, its output will latch off and a pull-up current source
is activated. This allows the output latch to automatically reset
when the load (such as a USB device) is removed. The output
can also be reset by toggling EN. Refer to Figure 1 for details.
Depending on PCB layout, package, ambient temperature,
etc., it may take several hundred milliseconds from the
incidence of the fault to the output MOSFET being shut off.
The worst-case scenario of thermal shutdown is that of a
short-circuit fault and is shown in the in the “Function Characteristics: Thermal Shutdown Response” graph.
March 2000
Total power dissipation of the device will be the summation of
PD for both channels. To relate this to junction temperature,
the following equation can be used:
TJ = PD × θJA + TA
where:
TJ = junction temperature
TA = ambient temperature
θJA = is the thermal resistance of the package
Current Sensing and Limiting
The current-limit threshold is preset internally. The preset
level prevents damage to the device and external load but still
allows a minimum current of 500mA to be delivered to the
load.
The current-limit circuit senses a portion of the output MOSFET switch current. The current-sense resistor shown in the
block diagram is virtual and has no voltage drop. The reaction
to an overcurrent condition varies with three scenarios:
Switch Enabled into Short-Circuit
If a switch is enabled into a heavy load or short-circuit, the
switch immediately enters into a constant-current mode,
reducing the output voltage. The FLG signal is asserted
indicating an overcurrent condition. See the Short-Circuit
Response graph under Functional Characteristics.

MIC2025/2075
MIC2025/2075
Micrel
Short-Circuit Applied to Enabled Output
When a heavy load or short-circuit is applied, a large transient
current may flow until the current-limit circuitry responds.
Once this occurs the device limits current to less than the
short-circuit current limit specification. See the Short-Circuit
Transient Response graph under Functional Characteristics.
Current-Limit Response—Ramped Load
The MIC2025/75 current-limit profile exhibits a small foldback
effect of about 200mA. Once this current-limit threshold is
exceeded the device switches into a constant current mode.
It is important to note that the device will supply current until
the current-limit threshold is exceeded. See the Current-Limit
Response graph under Functional Characteristics.
Fault Flag
The FLG signal is an N-channel open-drain MOSFET output.
FLG is asserted (active-low) when either an overcurrent or
thermal shutdown condition occurs. In the case where an
overcurrent condition occurs, FLG will be asserted only after
the flag response delay time, tD, has elapsed. This ensures
that FLG is asserted only upon valid overcurrent conditions
and that erroneous error reporting is eliminated. For example, false overcurrent conditions can occur during hot-plug
events when a highly capacitive load is connected and
causes a high transient inrush current that exceeds the
current-limit threshold. The FLG response delay time tD is
typically 3ms.
Undervoltage Lockout
Undervoltage lockout (UVLO) prevents the output MOSFET
from turning on until VIN exceeds approximately 2.5V. Undervoltage detection functions only when the switch is enabled.

Universal Serial Bus (USB) Power Distribution
The MIC2025/75 is ideally suited for USB (Universal Serial
Bus) power distribution applications. The USB specification
defines power distribution for USB host systems such as PCs
and USB hubs. Hubs can either be self-powered or buspowered (that is, powered from the bus). Figure 5 below
shows a typical USB Host application that may be suited for
mobile PC applications employing USB. The requirements
for USB host systems is that the port must supply a minimum
of 500mA at an output voltage of 5V ±5%. In addition, the
output power delivered must be limited to below 25VA. Upon
an overcurrent condition, the host must also be notified. To
support hot-plug events, the hub must have a minimum of
120µF of bulk capacitance, preferably low-ESR electrolytic or
tantulum. Refer to Application Note 17 for more details on
designing compliant USB hub and host systems.
For bus-powered hubs, USB requires that each downstream
port be switched on or off under control by the host. Up to four
downstream ports each capable of supplying 100mA at 4.4V
minimum are allowed. In addition, to reduce voltage droop on
the upstream VBUS, soft-start is necessary. Although the hub
can consume up to 500mA from the upstream bus the hub
must consume only 100mA max at start-up, until it enumerates with the host prior to requesting more power. The same
requirements apply for bus-powered peripherals that have no
downstream ports. Figure 6 shows a bus-powered hub.
Applications Information
Supply Filtering
A 0.1µF to 1µF bypass capacitor positioned close to VIN and
GND of the device 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.
Printed Circuit Board Hot-Plug
The MIC2025/75 are ideal inrush current-limiters suitable for
hot-plug applications. Due to the integrated charge pump,
the MIC2025/75 presents a high impedance when off and
slowly becomes a low impedance as it turns on. This “softstart” feature effectively isolates power supplies from highly
capacitive loads by reducing inrush current during hot-plug
events. Figure 3 shows how the MIC2075 may be used in a
hot-plug application.
In cases of extremely large capacitive loads (>400µF), the
length of the transient due to inrush current may exceed the
delay provided by the integrated filter. Since this inrush
current exceeds the current-limit delay specification, FLG will
be asserted during this time. To prevent the logic controller
from responding to FLG being asserted, an external RC filter,
as shown in Figure 4, can be used to filter out transient FLG
assertion. The value of the RC time constant will be selected
to match the length of the transient.
