Description

The CPC7581 is a monolithic solid-state four-pole switch in a 16-pin package. It provides the necessary functions to replace a 2-Form-C electromechanical relay on traditional analog and integrated voice and data (IVD) line cards found in central office, access, and PBX equipment. The CPC7581 contains solid-state switches for tip and ring lead line break and ringing injection/ringing return. The device requires only a +5 V supply, and offers break-before-make and make-before-break operation using logic-level inputs. The CPC7581BA versions include an SCR that provides protection to the SLIC and subsequent circuitry during a fault condition.

2 Functional Description

2.1 Introduction

The CPC7581 has three states:

  • Talk. Line break switches SW1 and SW2 closed, ringing switches SW3 and SW4 open.  Ringing. Ringing switches SW3 and SW4 closed, line break switches SW1 and SW2 open.  All-off. All switches open. See “Truth Table” on page 9 for more information. The CPC7581 offers break-before-make and make-before-break switching from the ringing state to the talk state with simple logic-level 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 logic-level input so no additional driver circuitry is required. The line break switches SW1 and SW2 are linear switches that have exceptionally low R ON and excellent matching characteristics. The ringing switch SW4 has a breakdown voltage rating of 465V @ 25°C. This is 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). Integrated into the CPC7581 is a over voltage clamping circuit, active current limiting, and a 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 hazardous potentials are steered to ground via diodes and, in CPC7581xA and CPC7581xC parts, an integrated SCR. Power-cross potentials are also reduced by the current limiting and thermal shutdown circuits. To protect the CPC7581 from an overvoltage fault condition, the 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 recommended. With proper selection of the secondary protector, a line card using the CPC7581 will meet all relevant ITU, LSSGR, TIA/EIA and IEC protection requirements. The CPC7581 operates from a +5 V supply only. This gives the device extremely low idle and active power consumption and allows use with virtually any range of battery voltage. 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 enters the all-off state.

2.2 Switch Logic

The CPC7581 provides, when switching from the ringing state to the talk state, the ability to control the release timing of the ringing switches SW3 and SW4 relative to the state of the line break switches SW1 and SW2 using simple logic-level input. This is called make-before-break or break-before-make operation. When the line break switch contacts (SW1 and SW2) are closed (or made) before the ringing switch contacts (SW3 and SW4) are opened (or broken), this is called make-before-break operation. Break-before-make operation occurs when the ringing contacts (SW3 and SW4) are opened (broken) before the line break contacts (SW1 and SW2) are closed (made). To use make-before-break ringing switch release timing, de-assert IN RINGING during ringing. This causes the operational sequence shown in “Make- Before-Break Operation Logic Table (Ringing to Talk Transition)” on page 11 to occur.

2.2.1 Make-Before-Break Oper ation Logic Table (Ringing to Talk Transition)

To use break-before-make ringing switch release timing, assert TSD during ringing. This causes the operational sequence shown in “Break-Before-Make Operation Logic Table (Ringing to Talk Transition)” on page 11 to occur. Logic states and explanations are given in “Truth Table” on page 9.

2.2.2 Break-Before-Make Oper ation Logic Table (Ringing to Talk Transition)

2.3 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 (IN RINGING), while the output of the data latch is an internal node used for state control. When the 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 the LATCH control pin is at logic 1, the data latch is 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. The T SD input is not tied to the data latch. Therefore, TSD is not affected by the LATCH input and the TSD input will override state control.

2.4 T SD

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 mode, pin 8 SD) will read a nominal 0 V. Normal output of TSD is typically 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 will activate forcing the switches to the all-off State INRINGING Latch TSD Timing Break Switches Ringing Return Switch (SW3) Ringing Switch (SW4) Ringing 1 -O f f On On Make- Before- Break SW4 waiting for next zero-current crossing to turn off.

INTEGRATED CIRCUITS DIVISION 12 www.ixysic.com R06 CPC7581 state. At this point the current measured through the break switches (SW1 and SW2) 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 return to normal operation. 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. The T SD pin is a pull-up current source with a nominal value of 300 A biased from VDD. For applications using low-voltage logic devices (lower than VDD), IXYS Integrated Circuits Division recommends the use of an open-drain type output to control TSD. This avoids sinking the TSD bias current to ground during normal operation when the all-off state is not required.

2.5 Ringing Switch Ze ro-Cross Current

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 ring generator is recommended.

2.6 Power Supplies

Both a +5 V supply and battery voltage are connected to the CPC7581. CPC7581 switch state control is powered exclusively by the +5 V supply. As a result, the CPC7581 exhibits extremely low power dissipation during both active and all-off states. The battery voltage is not used for switch control but rather as a supply for the integrated secondary protection circuitry. The integrated SCR is designed to trigger when pin 2 (T BAT) or pin 15 (RBAT) drops 2 to 4 V below the voltage on pin 16 (VBAT). This trigger prevents a fault-induced overvoltage event at the TBAT or RBAT nodes.

2.7 Battery Voltage Monitor

The CPC7581 also uses the VBAT voltage to monitor battery voltage. If system battery voltage is lost, the CPC7581 immediately enters 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 system battery voltage goes more positive than –10 V, and remains in the all-off state until the battery voltage goes more negative than –15 V. This battery monitor feature draws a small current from the battery (less than 1 A typical) and adds slightly to the device’s overall power dissipation. Due to the nature of the internal protection circuitry, the V BAT pin can be biased via potentials applied to TBAT or RBAT. This allows the CPC7581 switches to operate, but offers no transient protection. The supply voltage applied to VBAT should therefor be the same supply voltage applied to the line driver device.

2.8 Protection

2.8.1 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 to ground via F GND. Voltage is clamped to a diode drop above ground. During a negative transient of 2 to 4 V more negative than the battery, the SCR conducts and faults are shunted to F GND via the SCR or the diode bridge. In order for the SCR to crowbar (or foldback), the on voltage (see “Protection Circuitry Electrical

INTEGRATED CIRCUITS DIVISION CPC7581 R06 www.ixysic.com 13 Specifications” on page 9) of the SCR must be less negative than the battery reference voltage. If the battery voltage is less negative than the SCR on voltage, or if the V BAT supply is unable to source the trigger current, the SCR will not crowbar. 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 will cause the SCR to conduct when the voltage exceeds the battery reference voltage by two to four volts, steering the current to ground. Note: The CPC7581xB does not contain the protection SCR.

2.8.2 Current Limiting function

If a lightning strike transient occurs when the device in the talk 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 s pulse (GR-1089-CORE lightning) is applied to the line though a properly clamped external protector, the current seen through the break switches will be a pulse with a typical magnitude of 2.5 A and a duration of less than 0.5 s. If a power-cross fault occurs with the device in the talk 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 80 mA and 425 mA, 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 through the break switches (SW1 and SW2) 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.

2.9 External Protection Elements

The CPC7581 requires only overvoltage secondary protection on the loop side of the device. The integrated protection feature described above negates the need for protection on the other (usually SLIC) side. The secondary protector limits 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 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.
