Fairchild circuit protection is proud to offer a new type of
reverse bias protection devices. The FR devices are low
resistance, series switches that, in the event of a
reverse bias condition, shut off power and block the
negative voltage to help protect downstream circuits.

Automotive Peripherals
Reverse bias is an increasingly common fault event that
may be generated by user error, improperly installed
batteries,
automotive
environments,
erroneous
connections to third-party chargers, negative “hot plug”
transients, inductive transients, and readily available
negatively biased rouge USB chargers.
The FR devices are optimized for the application to offer
best in class reverse bias protection and voltage
capabilities while minimizing size, series voltage drop,
and normal operating power consumption.
USB Charging
In the event of a reverse bias application, FR011L5J
devices effectively provide a full voltage block and can
easily protect -0.3V rated silicon.

From a power perspective, in normal bias, an 11mΩ FR
device in a 1.5A application will generate only 17mV of
voltage drop or 25mW of power loss. In reverse bias,
FR devices dissipate less then 20µW in a 16V reverse
bias event. This type of performance is not possible with
a diode solution.
Benefits extend beyond the device. Due to low power
dissipation, not only is the device small, but heat sinking
requirements and cost can be minimized as well.

Notes:
1. The V+24 rating is NOT a survival guarantee. It is a statistically calculated survivability reference point taken on
qualification devices, where the predicted failure rate is less than 0.01% at the specified voltage for 24 hours. It is
intended to indicate the device’s ability to withstand transient events that exceed the recommended operating
voltage rating. Specification is based on qualification devices tested using accelerated destructive testing at
higher voltages, as well as production pulse testing at the V+24 level. Production device field life results may vary.
Results are also subject to variation based on implementation, environmental considerations, and circuit
dynamics. Systems should never be designed with the intent to normally operate at V+24 levels. Contact Fairchild
Semiconductor for additional information.
2. The device power dissipation and thermal resistance (Rθ) are characterized with device mounted on the following
FR4 printed circuit boards, as shown in Figure 4 and Figure 5

Application Information
USB3.0 device is reversely biased; the output voltage is
near 0 and response time is less than 50ns.
Figure 17 shows the voltage and current waveforms
when a virtual USB3.0 device is connected to a 5V
source. A USB application allows a maximum source
output capacitance of C1 = 120µF and a maximum
device-side input capacitance of C2 = 10µF plus a
maximum load (minimum resistance) of R3 = 27Ω. C1 =
100µF, C2 = 10µF and R3 = 27Ω were used for testing.
Figure 19 shows the voltage and current waveforms
when no reverse bias protection is implemented. In
Figure 17, while the reverse bias protector is present,
the input voltage, VIN, and the output voltage, VO, are
separated and look different. When this reverse bias
protector is removed, VIN and VO merge, as shown
inFigure 19 as VIN. This VIN is also the voltage applied to
the load circuit. It can be seen that, with reverse bias
protection, the voltage applied to the load and the
current flowing into the load look very much the same as
without reverse bias protection.
When the DC power source is connected to the circuit
(refer to Figure 13), the built-in startup diode initially
conducts the current such that the USB device powers
up. Due to the initial diode voltage drop, the FR011L5J
effectively reduces the peak inrush current of a hot plug
event. Under these test conditions, the input inrush
current reaches about 6.3A peak. While the current
flows, the input voltage increases. The speed of this
input voltage increase depends on the time constant
formed by the load resistance R3 and load capacitance
C2. The larger the time constant, the slower the input
voltage increase. As the input voltage approaches a
level equal to the protector’s turn-on voltage, VON, the
protector turns on and operates in Low-Resistance
Mode as defined by VIN and operating current IIN.
Benefits of Reverse Bias Protection
The most important benefit is to prevent accidently
reverse-biased voltage from damaging the USB load.
Another benefit is that the peak startup inrush current
can be reduced. How fast the input voltage rises, the
input/output capacitance, the input voltage, and how
heavy the load is determine how much the inrush
current can be reduced. In a 5V USB application, for
example, the inrush current can be 5% - 20% less with
different input voltage rising rate and other factors. This
can offer a system designer the option of increasing C2
while keeping “effective” USB device capacitance down.
In the event of a negative transient, or when the DC
power source is reversely connected to the circuit, the
device blocks the flow of current and holds off the
voltage, thereby protecting the USB device. Figure 18
shows the voltage and current waveforms when a virtual
