DS-CPC7581-R2
The CPC7581 is a monolithic solid state switch in a 16 pin
surface mount SOIC package. It provides the necessary
functions to replace a 2-Form-C electromechanical relay
on analog line cards found in Central Office, Access and
PBX equipment. The device contains solid state switches
for tip and ring line break and ring injection/ring return.
The CPC7581 requires only a +5V supply and offers
“break-before-make” or “make-before-break” switch operation using simple logic level input control. There are two
versions of the CPC7581, the CPC7581BA and the
CPC7581BB. The “BA” version has a protection SCR
which provides protection to the SLIC device and subsequent circuitry during fault conditions.

CPC7581
Rev. 2
Functional Description
Introduction
The CPC7581 has three states:
• Idle/talk state (line break switches SW1, and SW2
closed, ringing switches SW3, SW4 open)
• Ringing state (line break switches SW1, and SW2
open, ringing switches SW3, SW4 closed)
• All Off state (line break switches SW1, and SW2
open, ringing switches SW3, SW4 open)
The CPC7581 offers break-before-make and makebefore-break switching with simple logic level input control. Solid state switch construction means no impulse
noise is generated when switching during ring cadence
or ring trip, thus eliminating the need for external “zero
cross” switching circuitry. State control is via logic level
input so no additional driver circuitry is required. The line
break switches SW1 and SW2 are linear switches that
have exceptionally low RDSON and excellent matching
characteristics. The ringing access switch SW4 has a
breakdown voltage rating of >480V which is sufficiently
high, with proper protection, to prevent breakdown in the
presence of a transient fault condition.
Integrated into the CPC7581 is a diode bridge/SCR
clamping circuit, current limiting and thermal shutdown
mechanism to provide protection to the SLIC device
during a fault condition. Positive and negative surges
are reduced by the current limiting circuitry and steered
to ground via diodes and the integrated SCR. Power
cross transients are also reduced by the current limiting
and thermal shutdown circuits. Please note that only
the CPC7581BA has the integrated protection SCR.
To protect the CPC7581 from an overvoltage 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 max breakdown voltage of the switches. To minimize the stress on
the solid-state contacts, use of a foldback or crowbar
type secondary protector is recommended. With proper
selection of the secondary protector, a line card using
the CPC7581 will meet all relevant ITU, LSSGR, FCC
or UL protection requirements.
The CPC7581 operates from a +5V supply only. This
gives the device extremely low idle and active power dissipation and allows use with virtually any range of battery
voltage. A battery voltage is also used by the CPC7581
as a reference for the integrated protection circuit. In the
event of a loss of battery voltage, the CPC7581 will enter
an “all off” state.
Switch Timing
The CPC7581 provides, when switching from the ringing
state to the idle/talk state, the ability to control the timing
when the ringing access switches SW3 and SW4 are
released relative to the state of the line break switches
SW1 and SW2 using simple logic level input. This is
referred to a “make before break” or “break before make”
operation. When the line break switch contacts (SW1,
SW2) are closed (or made) before the ringing access
switch contact (SW3, SW4) is opened (or broken), this is
referred to a “make-before-break” operation. “Breakbefore-make” operation occurs when the ringing access
contact (SW3, SW4) is opened (broken) before the line
break switch contacts (SW1, SW2) are closed (made).
With the CPC7581 the “make before break” and “break
before make” operations can easily be selected by applying logic level inputs to pin 10 of the device.
The logic sequences for either mode of operation are
given in Tables 5 and 6. Logic states and explanations
are given in Table 8.
Ring Access Switch Zero Cross Current Turn Off
After the application of a logic input to turn SW4 off, the
ring access 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 what logic
input until the next zero crossing. For proper operation,
pin 12 (R
Ring
) should be connected using proper impedance to a ring generator or other AC source. These
switching characteristics will reduce and possibly eliminate overall system impulse noise normally associated
with ringing access switches. The attributes of ringing
access switch SW4 may make it possible to eliminate
the need for a zero cross switching scheme. A minimum
impedance of 300Ω in series with the ring generator is
recommended.
Power Supplies
Both a +5V supply and battery voltage are connected
to the CPC7581. CPC7581 switch state control is powered exclusively by the +5V supply. As a result, the
CPC7581 exhibits extremely low power dissipation during both active and idle states.
The battery voltage is not used for switch control but
rather as a reference by the integrated secondary protection circuitry. The integrated SCR is designed to trigger when pin 2 (T
BAT
) or pin 15 (R
BAT
) drops 2 to 4V
below the battery. This trigger prevents a fault induced
overvoltage event at the T
BAT
or R
BAT
nodes.

Rev. 2
Battery Voltage Monitor
The CPC7581 also uses the voltage reference to monitor battery voltage. If battery voltage is lost, the CPC7581
will immediately enter the “all off” state and remain in this
state until the battery voltage is restored. The device will
also enter the “all off” state if the battery voltage rises
above –10V and will remain there until the battery voltage drops below –15V. This battery monitor feature
draws a small current from the battery (< 1µA typ.) and
will add slightly to the device’s overall power dissipation.
Protection
Diode Bridge/SCR
The CPC7581 uses a combination of current limited
break switches, a diode bridge/SCR clamping circuit
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 and to ground. Voltage is
clamped to the diode drop above ground. During a negative transient of two to four volts more negative than
the battery, the SCR conducts and faults are shunted to
ground via the SCR and diode bridge.
Also, in order for the SCR to crowbar or foldback, the on
voltage (see Table 7) of the SCR must be less negative
than the battery reference voltage. If the battery voltage
is less negative the SCR on voltage, the SCR will not
crowbar, however it will conduct fault currents to ground.
For power induction or power cross fault conditions, the
positive cycle of the transient is clamped to the diode
drop above ground and the fault current directed to
ground. The negative cycle of the transient will cause
the SCR to conduct when the voltage exceeds the battery reference voltage by two to four volts, steering the
current to ground.
Current Limiting function
If a lightning strike transient occurs when the device in
the talk/idle state, the current is passed along the line to
the integrated protection circuitry and limited by the
dynamic current limit response of break switches SW1
and SW2. When a 1000V 10x1000 pulse (LSSGR lightning) is applied to the line though a properly clamped
external protector, the current seen at pins 2 (T
BAT
) and
pin 15 (R
BAT
) will be a pulse with a typical magnitude
and duration of 2.5A and < 0.5ms.
If a power cross fault occurs with device in the talk/idle
state, the current is passed though the break switches
SW1 and SW2 on to the integrated protection circuit
and is limited by the dynamic DC current limit response
of the two break switches. The DC current limit, specified
over temperature, is between 80mA and 425mA and the
circuitry has a negative temperature coefficient. As a
result, if the device is subjected to extended heating due
to power cross fault, the measured current at pin 2 (T
BAT
)
and pin 15 (R
BAT
) will decrease as the device temperature increases. If the device temperature rises sufficiently, the temperature shutdown mechanism will activate
and the device will default to the “all off” state.
Temperature Shutdown
The thermal shutdown mechanism will activate when
the device temperature reaches a minimum of 110°C
placing the device in the “all off” state regardless of logic
input. During this thermal shutdown mode, pin 8 (TSD)
will read 0V. Normal output of TSD is +V
DD
If presented with a short duration transient such as a
lightning event, the thermal shutdown feature will not
typically activate. But in an extended power cross transient, the device temperature will rise and the thermal
shutdown will activate forcing the switches to an “all off”
state. At this point the current measured at pin 2 (T
BAT
)
and pin 15 (R
BAT
) 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 activation level of the thermal shutdown circuit. This
will return the device to the state prior to thermal shutdown. If the transient has not passed, current will flow
at the value allowed by the dynamic DC current limiting
of the switches and heating will begin again, 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 could activate and shunt
all current to ground.
External Protection Elements
The CPC7581 requires only one overvoltage secondary
protector on the loop side of the device. The integrated
protection feature described above negates the need
for protection on the line side. The purpose of the secondary protector is to limit voltage transients to levels
that do not exceed the breakdown voltage or input-output isolation barrier of the CPC7581. A foldback or
crowbar type protector is recommended to minimize
stresses on the device.
Consult Clare’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.

Rev. 2
Data Latch
The CPC7581 has an integrated data latch. The latch
operation is controlled by logic level input pin 11
(LATCH). The data input of the latch is pin 10 (INPUT)
and of the device while the output of the data latch is an
internal node used for state control. When LATCH control pin is at logic 0, the data latch is transparent and data
control signals flow directly through to state control. A
change in input will be reflected in a change is switch
state. When LATCH control pin is at logic 1, the data
latch is now active and a change in input control will not
affect switch state. The switches will remain in the position they were in when the LATCH changed from logic 0
to logic 1 and will not respond to changes in input as long
as the latch is at logic 1. In addition, TSD input is not tied
to the data latch. Therefore, TSD is not affected by the
LATCH input and TSD input will override state control via
pin 10 (IN
RING
) and the LATCH.
