DESCRIPTION
The SP2526 device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for
self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low
on-resistance (80mΩ typical) and can supply 500mA minimum. The fault currents are limited
to 2.0A typical and the flag output pin for each switch is available to indicate fault conditions
to the USB controller. The 1ms soft start will eliminate any momentary voltage droop on the
upstream port that may occur when the switch is enabled in bus-powered applications. The
thermal shutdown feature will prevent damage to the device when subjected to excessive
current loads. The undervoltage lockout feature will ensure that the device will remain off
unless there is a valid input voltage present.

Input and Output
The independent solid state MOSFET switches
connect the USB +5.0V supply voltage at the IN
pin to the OUTA and OUTB pins when enabled
by logic signals at ENA and ENB. The IN pin is
the power supply connection to the device and the
drain of the output MOSFET switches.
FEATURES
Features of the SP2526 device include current
limiting, a +2.7V undervoltage lockout, overtemperature shutdown, error flag output, soft
start, a switch-on resistance of 100mΩ over the
entire supply range, and a supply current of
100µA. The SP2526-1 device has an activehigh enable. The SP2526-2 device has an
active-low enable.
Typically, the current will flow through the
switches from IN to OUTA and OUTB towards
the load. If VOUT is greater than VIN when a switch
is enabled, the current will flow from OUTA or
OUTB to the IN pin because the MOSFET channels are bidirectional when switched on.
THEORY OF OPERATION
The SP2526 is a dual integrated high-side power
switch optimized for self-powered and buspowered Universal Serial Bus (USB) applications. There are operational conditions that will
enable or disable one or more of the output
MOSFET switches, depending on the type of
hazard. Certain conditions will activate the
open-drain error flag transistors forcing the flag
outputs to ground. The SP2526 provides the
following functions:
Under normal operating condition, the MOSFET
switches will present 100mΩ maximum resistance when closed. The output MOSFETs and
driver circuitry are designed to allow the MOSFET
source to be externally forced to a higher voltage
than the drain when the switch is off.
Fault Flag Conditions
Fault conditions disable one or both MOSFET
switches, depending on the type of fault. FLGA
and FLGB are N-channel, open-drain MOSFET
outputs. The active low fault flag occurs when
one of the following conditions exist:
1) Independent Solid State Switches: Independent MOSFET switches connect the IN pin to
the OUTA and OUTB pins when enabled by
logic signals at the ENA and ENB control pins.
1. Undervoltage
2. Overcurrent
3. Overtemperature
2) Fault Flag Conditions: Both the FLGA and
FLGB pins are N-channel, open-drain MOSFET
outputs capable of sinking a 10mA load to
typically 100mV above ground.
Undervoltage Lockout
This voltage lockout mechanism prevents the
MOSFET switches from turning on until VIN is
greater than +2.7V.
3) Undervoltage Lockout: The lockout mechanism monitors the input voltage and will enable
the MOSFET switches only when the voltage at
the VIN pin is greater than +2.7V.
After the switch turns on, if the voltage at VIN
drops below +2.6V, the lockout circuitry shuts off
both switches and signals the FLGA and FLGB
fault flags. In the undervoltage lockout state, the
FLGA and FLGB pins will be asserted. This
detection functions only when at least one
MOSFET switch is enabled.
4) Current Limiting Threshold: A current
limiting threshold prevents damage to the device and external load.
5) Thermal Shutdown: This mechanism protects the SP2526 and signals a fault condition if
the die temperature exceeds 135OC (typical).
This function has 10OC of hysteresis that prevents the MOSFET switches from turning on
until the die temperature drops to 125OC (typical).
Rev. 8/21/01
Output Current Limiting
The SP2526 has a preset current-limit threshold.
These switch control circuits will implement
current limiting which prevents damage to the
SP2526 and the external load while allowing a

minimum current of 0.5A to be delivered.
The delay between a current limit fault and
thermal shutdown will vary with ambient temperature, board layout, and load impedance, but
is typically several hundred milliseconds. A
designer
can command a USB controller to recognize the
fault and disable the appropriate channel within
this time.
The SP2526 MOSFET switches will exhibit
very low resistance (<100mΩ) or voltage drop
until the current limit is reached. The fold back
current is the current that is delivered into a short
circuit at the output.
If the SP2526 MOSFET switch is enabled into a
heavy load or short-circuit, the switch will immediately go into a constant-current mode, reducing the output voltage. The respective fault
flag will pull low until the condition is removed.
TYPICAL APPLICATIONS
Bypass Capacitors
A 0.1µF to 1.0µF bypass capacitor from the IN
pin to the GND pin is recommended to control
power supply transients. Refer to Figure 4.
Without a bypass capacitor, an output short may
cause sufficient ringing and damage the device.
Without a bypass capacitor, excessive supply
lead inductance is also a concern.
When a heavy load is connected to the SP2526
switch output, a large transient current may flow
until the current limiting circuitry responds.
The SP2526 will provide a low resistance switch
(100mΩ) between the input and output pins.
This low resistance will be maintained with
increasing current until the 2.2A limit is reached.
If load current exceeds this limit, the switch will
increase its resistance. The foldback current
(500mA minimum) is reached when there is a
short applied to the output. The 100mΩ switch
resistance is guaranteed for all load currents,
increasing or decreasing, that are below 500mA.
Input or output transients must not exceed the
absolute maximum supply voltage of VIN(MAX) =
+6.0V even for a short duration to avoid risk of
damage to the device.
Transient Overcurrent Filter
When the SP2526 is enabled, large values of
capacitance at the output of the device will cause
inrush current to exceed the short circuit currentlimit threshold of the device and assert a flag
fault condition for FLGA and/or FLGB. The
duration of this time will depend on the size of
the output capacitance. During the capacitance
charging time, the device enters into foldback
mode. As the capacitance is charged, the current
decreases below the current-limit threshold and
the fault flags that are present at the FLGA and/
or FLGB pins will then be deasserted.
Thermal Shutdown
Under nominal load conditions, the switch resistance is very low and internal power dissipation
is low. Under short circuit conditions, current is
limited and internal power dissipation is higher
but not extreme. Under intermediate load conditions, both the voltage across the switch and the
current through the switch are at intermediate
values and internal power dissipation is highest.
In this last condition, the die temperature will
reach the thermal limit and the switches in both
channels will be shut off. As the die subsequently cools, the switch will turn on again. If
the load is not removed, the device will thermal
cycle in this manner to protect itself from damage.
In USB applications, it is required that output
bulk capacitance is utilized to support hot-plug
occurences. When the SP2526 is enabled, the
flag may go active for about 1ms due to inrush
current exceeding the current-limit setpoint.
Additionally, during hot-plug events, inrush currents may also cause the fault flags at the FLGA
and/or FLGB pins to go active. Since these
conditions are not valid overcurrent faults, the
USB controller must ignore the fault flags during
these events. To prevent this, a 1ms RC filter can
be implemented as shown in Figure 5. Alterna-
Thermal shutdown is asserted if the die temperature exceeds 135OC and will not release until the
die termperature drops below 125OC. Thermal
shutdown will disable both output MOSFET
switches and force both FLGA and FLGB fault
flags low.

tively, a 1ms debounce routine may be programmed into the USB logic controller, eliminating the need for the RC filter.
4) Each MOSFET switch channel can supply
500mA as required by USB downstream devices;
Soft Start Condition
The soft start feature of the SP2526 is implemented by holding the output turn-on rise time
to 1ms. When off, the device has high impedance MOSFET channels that slowly become
low impedance as the device powers on. This
prevents an inrush current from causing voltage
drops that result from charging a capacitive
load and can pull the USB voltage bus below
specified levels. This satisfies the USB voltage
droop requirements for bus-powered applications. Refer to the circuit in Figure 6.
5) Soft start eliminates any momentary voltage
drops on the upstream port that may occur when
the switches are enabled in bus-powered applications.
The SP2526 can provide inrush current limiting
for applications with large load capacitances
where CBULK > 10µF. Refer to the circuit in
Figure 7 for a configuration that will meet USB
transient regulation specifications with large
load capacitances.
7) +3.3V and +5.0V logic compatible enable
inputs;
Enable Input
The ENA and ENB control pins must be driven
to a logic high or logic low for a clearly defined
signal input. Floating these control lines may
cause unpredictable operation.
8) The device is available in both active-high and
active-low versions.
Refer to Table 1 for a USB compliance summary
of the SP2526. Additional features include the
following:
6) An Undervoltage Lockout ensures that the
device remains off unless there is a valid input
supply voltage present;
8) Thermal Shutdown prevents the possiblity of
catastrophic switch failure from high-current
loads;
Refer to Figures 8 to 26 for typical performance
characteristics of the SP2526.
USB Compliance
The SP2526 is ideal for self-powered and buspowered Universal Serial Bus (USB) applications. A USB port provides a +5.0V bus and
ground return line in addition to a twisted pair
for data.
The SP2526 will comply with the following
USB requirements:
1) The fault current is well below the UL 25VA
safety requirements;
2) The Flag Outputs are available to indicate
fault conditions to USB controllers;
3) The MOSFET switches' low on-resistance
meets USB voltage drop requirements;
