away from the SLIC via the protection diode bridge.
Power-cross potentials are also reduced by the current
limiting and thermal shutdown circuits.
2.1 Introduction
The CPC75282 Dual LCAS device has six operating
states:
• Idle/Talk: Break switches SW1 and SW2 closed,
ringing switches SW3 and SW4 open, and test
switches SW5 and SW6 open.
• Ringing: Break switches SW1 and SW2 open,
ringing switches SW3 and SW4 closed, and test
switches SW5 and SW6 open.
• Test: Break switches SW1 and SW2 open, ringing
switches SW3 and SW4 open, and loop test
switches SW5 and SW6 closed.
• Test/Monitor: Break switches SW1 and SW2
closed, ringing switches SW3 and SW4 open, and
test switches SW5 and SW6 closed.
• Test Ringing: Break switches SW1 and SW2 open,
ringing switches SW3 and SW4 closed, and test
switches SW5 and SW6 closed.
• All-off: Break switches SW1 and SW2 open, ringing
switches SW3 and SW4 open, and test switches
SW5 and SW6 open.
To protect the CPC75282 from an over-voltage fault
condition, use of a secondary protector is required.
The secondary protector must limit the voltage seen at
the tip and ring terminals to a level below the
maximum breakdown voltage of the switches. To
minimize the stress on the solid-state contacts, use of
a foldback or crowbar type secondary protector is
highly recommended. With proper selection of the
secondary protector, a line card using the CPC75282
will meet all relevant ITU, LSSGR, TIA/EIA and IEC
protection requirements.
The CPC75282 operates from a single +5V supply.
This gives the device extremely low idle and active
power consumption with virtually any range of battery
voltage. The battery voltage used by the CPC75282
has a two-fold function. For protection purpose it is
used as a fault condition current source during a
negative lightning event. Second, it is used as a
reference so that in the event of battery voltage loss,
the CPC75282 will enter the All-Off state.
See “Truth Tables” on page 11 for more information.
2.2 Under Voltage Switch Lock-Out Circuitry
The CPC75282 offers break-before-make and
make-before-break switching from the ringing state to
the idle/talk state with simple logic input control.
Solid-state switch construction means no impulse
noise is generated when switching during ring
cadence or ring trip, eliminating the need for external
zero-cross switching circuitry. State control is via
simple logic input so no additional driver circuitry is
required. The linear break switches, SW1 and SW2,
have exceptionally low RON and excellent matching
characteristics. The ringing switch, SW4, has a
minimum open contact breakdown voltage of 465V at
+25°C sufficiently high with proper protection to
prevent breakdown in the presence of a transient fault
condition (i.e., passing the transient on to the ringing
generator).
Smart logic in the CPC75282 now provides for switch
state control during both power up and power loss
transitions. An internal detector is used to evaluate the
VDD supply to determine when to de-assert the
under-voltage switch lock-out circuitry with a rising
VDD and when to assert the under-voltage switch
lock-out circuitry with a falling VDD. Any time
unsatisfactory low VDD conditions exist, the lock-out
circuit overrides user switch control by blocking the
information at the external input pins, and conditioning
internal switch commands to the All-Off state. Upon
restoration of VDD, the switches will remain in the
All-Off state until the LATCHx input is pulled low.
Integrated into the CPC75282 is an over-voltage
clamping circuit, active current limiting, and a thermal
shutdown mechanism to provide protection for the
SLIC during a fault condition. Positive and negative
lightning surge currents are reduced by the current
limiting circuitry and hazardous potentials are diverted
12
The rising VDD lock-out release threshold is internally
set to ensure all internal logic is properly biased and
functional before accepting external switch commands
from the input to control the switch states. For a falling
VDD event, the lock-out threshold is set to assure
proper logic and switch behavior up to the moment the
switches are forced off and external inputs are
suppressed.

2.3 Switch Logic
With the CPC75282, make-before-break and
break-before-make operations can easily be
accomplished by applying the proper sequence of
logic-level inputs to the device.
2.3.1 Start-up
The CPC75282 uses smart logic to monitor the VDD
supply. Any time the VDD is below an internally set
threshold, the smart logic places the control logic to
the all-off state until the LATCHx input is pulled low.
Prior to the assertion of a logic low at the LATCHx pin,
the switch control inputs must be properly conditioned.
2.3.2 Switch Timing
When switching from the ringing state to the idle/talk
state, the CPC75282 provides the ability to control the
release timing of the ringing switches, SW3 and SW4,
relative to the state of the switches, SW1 and SW2,
using simple logic inputs. The two available
techniques are referred to as make-before-break and
break-before-make operation. When the break switch
contacts of SW1 and SW2 are closed (made) before
the ringing switch contacts of SW3 and SW4 are
opened (broken), this is referred to as
make-before-break operation. Break-before-make
operation occurs when the ringing contacts of SW3
and SW4 are opened (broken) before the switch
contacts of SW1 and SW2 are closed (made).
The logic sequences for either mode of operation are
given in “Make-Before-Break Operation Logic
Table (Ringing to Talk Transition)” on page 13 and
“Break-Before-Make Ringing to Talk Transition
Logic Sequence CPC7592xA/B” on page 14. Logic
states and explanations are shown in “Truth Tables”
on page 11.
2.3.3 Make-Before-Break Operation
To use make-before-break operation, change the logic
inputs from the ringing state directly to the idle/talk
state. Application of the idle/talk state opens the
ringing return switch, SW3, as the break switches,
SW1 and SW2, close. The ringing switch, SW4,
remains closed until the next zero-crossing of the
ringing current. While in the make-before-break state,
ringing potentials in excess of the CPC75282
protection circuitry thresholds will be diverted away
from the SLIC.

2.3.6 Break -Before- Make Operation
Break-before-make operation can be achieved using
OFFx to disable all of the switches when pulled to a
logic low. Although logically disabled, an active
(closed) ringing switch, SW4, will remain closed until
the next zero crossing current event.
1. Pull OFFx to a logic low to end the ringing state.
This opens the ringing return switch, SW3, and
prevents any other switches from closing.
2. Keep OFFx low for at least one-half the duration
of the ringing cycle period to allow sufficient time
for a zero crossing current event to occur and for
the circuit to enter the break-before-make state.
3. During the OFFx low period, set the P1, P2, and
P3 inputs to the idle/talk state.
4. Release OFFx , allowing the internal pull-up to
activate the break switches.
2.4 Data Latch
The CPC75282 has integrated transparent data
latches. The latch enable operation is controlled by
logic input levels at the LATCHx pin. Data input to the
latch is via the input pins P1, P2, and P3 while the
outputs of the data latch are internal nodes used for
state control. When the latch enable control pin is at a
logic 0 the data latch is transparent and the input
control signals flow directly through the data latch to
the state control circuitry. A change in input will be
reflected by a change in the switch states.

Whenever the latch enable control pin is at logic 1, the
data latch is active and data is locked. Subsequent
changes to the input controls P1, P2, and P3 will not
result in a change to the control logic or affect the
existing switch states.
The switches will remain in the state they were in
when the LATCHx changes from logic 0 to logic 1, and
will not respond to changes in input as long as the
LATCHx is at logic 1. However, neither the TSDx nor
the OFFx are affected by the latch function. Since
internal thermal shutdown control and external OFFx
control is not affected by the state of the latch enable
input, TSDx and OFFx will override state control.
2.5 TSD Pin Description
The TSDx pins are bidirectional I/O structures with
internal pull-up resistors sourced from VDD. As
outputs, these pins indicate the status of the thermal
shutdown circuitry for the associated channels.
Typically, during normal operation, these pins will be
pulled up to VDD , but, under fault conditions that
create excess thermal loading, the channels will enter
thermal shutdown and a logic low will be output.
As inputs, the TSDx pins are utilized to place the
channel into the All-Off state by simply pulling the
input low. For applications using low-voltage logic
devices (lower than VDD), IXYS Integrated Circuits
Division recommends the use of an open-collector or
an open-drain type output to control TSDx. This avoids

sinking the TSDx pull up bias current to ground during
normal operation when the All-Off state is not
required. If TSDx is set to a logic 1 or tied to VCC, the
channel just ignores this input, and still enters the
thermal shutdown state at high temperature.
battery monitor feature draws a small current from the
battery (less than 1A typical) and will add slightly to
the device’s overall power dissipation.
2.9 Protection
2.9.1 Diode Bridge
2.6 Ringing Switch Zero-Cross Current Turn Off
After the application of a logic input to turn SW4 off,
the ringing switch is designed to delay the change in
state until the next zero-crossing. Once on, the switch
requires a zero-current cross to turn off, and therefore
should not be used to switch a pure DC signal. The
switch will remain in the on state no matter the logic
input until the next zero crossing. These switching
characteristics will reduce and possibly eliminate
overall system impulse noise normally associated with
ringing switches. See IXYS Integrated Circuits
Division’s application note, AN-144, Impulse Noise
Benefits of Line Card Access Switches, for more
information. The attributes of ringing switch, SW4,
may make it possible to eliminate the need for a
zero-cross switching scheme. A minimum impedance
of 300 in series with the ringing generator is
recommended.
2.7 Power Supplies
Both a +5V supply and battery voltage are connected
to the CPC75282. Switch state control is powered
exclusively by the +5V supply. As a result, the
CPC75282 exhibits extremely low power consumption
during active and idle states. Although battery power
is not used for switch control, it is required to supply
current during negative overvoltage fault conditions at
tip and ring.
2.8 Battery Voltage Monitor
The CPC75282 also uses the VBAT voltage to monitor
battery voltage. If system battery voltage is lost, both
channels of the CPC75282 immediately enter the
All-Off state. It remains in this state until the battery
voltage is restored. The device also enters the All-Off
state if the battery voltage rises more positive than
about –10V with respect to ground and remains in the
All-Off state until the battery voltage drops below
approximately –15V with respect to ground. This
R00E
Both channels of the CPC75282 use a combination of
current limited break switches, a diode bridge, and a
thermal shutdown mechanism to protect the SLIC
device or other associated circuitry from damage
during line transient events, such as lightning. During
a positive transient condition, the fault current is
conducted through the diode bridge to ground via
FGND. Voltage is clamped to a diode drop above
ground. Negative lightning is directed to battery via
steering diodes in the diode bridge. For power
induction or power-cross fault conditions, the positive
cycle of the transient is clamped to a diode drop above
ground and the fault current directed to ground. The
negative cycle of the transient is steered to battery.
Fault currents are limited by the current-limit circuit.
2.9.2 Current Limiting function
If a lightning strike transient occurs when the device is
in the Idle/Talk state, the current is passed along the
line to the integrated protection circuitry, and restricted
by the dynamic current limit response of the active
switches. During the Idle/Talk state, when a 1000V
10x1000 s lightning pulse (GR-1089-CORE
lightning) is applied to the line though a properly
clamped external protector, the current seen at TLINE
and RLINE will be a pulse with a typical magnitude of
2.5A and a duration less than 0.5s.
If a power-cross fault occurs with the device in the
Idle/Talk state, the current is passed though break
switches, SW1 and SW2, on to the integrated
protection circuit, but is limited by the DC current limit
response of the two break switches. The DC current
limit is dependent on the switch differential voltage, as
shown in “Figure 2: Switches 1-3” on page 17.
Note that the current limit circuitry has a negative
temperature coefficient. As a result, if the device is
subjected to extended heating due to a power cross
fault condition, the measured current at TLINE and
RLINE will decrease as the device temperature

increases. If the device temperature rises sufficiently,
the temperature shutdown mechanism will activate
and the device will enter the All-Off state.
2.10 Thermal Shutdown
The thermal shutdown mechanism activates when the
device die temperature reaches a minimum of 110°C,
placing the device in the All-Off state regardless of
logic input. During thermal shutdown events the TSDx
pin will output a logic low with a nominal 0V level. A
logic high is output from the TSDx pin during normal
operation with a typical output level equal to VDD.
If presented with a short duration transient, such as a
lightning event, the thermal shutdown feature will
typically not activate. But in an extended power-cross
event, the device temperature will rise and the thermal
shutdown mechanism will activate forcing the switches
to the All-Off state. At this point the current measured
into TLINE or RLINE will drop to zero. Once the device
enters thermal shutdown, it will remain in the All-Off
state until the temperature of the device drops below
the de-activation level of the thermal shutdown circuit.
This permits the device to autonomously return to
normal operation. If the transient has not passed,
current will again flow up to the value allowed by the
dynamic DC current limiting of the switches and
16
heating will resume, reactivating the thermal shutdown
mechanism. This cycle of entering and exiting the
thermal shutdown mode will continue as long as the
fault condition persists. If the magnitude of the fault
condition is great enough, the external secondary
protector will activate, shunting the fault current to
ground.
2.11 External Protection Elements
The CPC75282 requires only over-voltage secondary
protection on the loop side of the device. The
integrated protection feature described above negates
the need for additional external protection on the SLIC
side. The secondary protector must limit voltage
transients to levels that do not exceed the breakdown
voltage or input-output isolation barrier of the
CPC75282. A foldback or crowbar type protector is
recommended to minimize stresses on the
CPC75282.
Consult IXYS Integrated Circuits Division’s application
note, AN-100, “Designing Surge and Power Fault
Protection Circuits for Solid State Subscriber Line
Interfaces,” for equations related to the specifications
of external secondary protectors, fused resistors, and
PTCs.
