Description
The CPC1563 is a normally open (1-Form-A) Solid
State Relay with an integrated current limit feature
that targets the international hook switch telephony
market by providing excellent power-cross immunity
for improved survivability in harsh environments.

When a fault condition occurs, usually in the form of
a voltage rise across the load/relay combination, the
relay will limit the current flow through the load to ILMT
As the fault voltage increases, the load is protected
by the relay's current limit, but the relay itself must
dissipate more and more power. If, while the relay is
in current limit, the voltage dropped across the relay
rises to the Voltage Triggered Shutdown threshold,
VTH, then the current through the relay, and the load,
is cut to a nominal 100A.
Features
• Integrated Active Current-Limit with
Voltage Triggered Shutdown
• Thermal Shutdown
.
• Guaranteed Turn-On: 2mA Input Control Current
• 600VP Blocking Voltage
• 3750Vrms Input/Output Isolation
• Small Surface Mount Package
• Low Drive Power Requirements
• Arc-Free With No Snubbing Circuits
• No EMI/RFI Generation
In the event of a fault condition that persists, and with
or without VTH being exceeded, the temperature of
the relay's die could rise to a level that might damage
it. In this instance, internal thermal management
circuitry shuts the relay down.
• Flammability Rating UL 94 V-0
Applications
• Simplifies Telecom Secondary Protection
• Telephony Hook Switch
• VoIP Gateways
When the voltage across the relay drops below VTH,
and if the device is not in thermal shutdown, normal
operation is restored. If the fault condition persists,
then the events described above repeat.
• IP-PBXs
When provided with adequate overvoltage protection,
the CPC1563 can pass regulatory voltage surge
requirements. The CPC1563 relay may be used in
both AC and DC applications.
