Features
• Integrated Active Current-Limit Protection
• Thermal Shutdown
• Linear AC or DC Operation
• Low Power Consumption
• Clean, Bounce-free Switching
• High Surge Capability
• Low Power Drive Requirements
• Surface Mount version available
• Tape & Reel packaging available
The relay is constructed using a GaAIAs LED for
actuation control and an integrated monolithic
die for the switch output. The die, fabricated in a
high-voltage dielectrically isolated technology, is
comprised of a photodiode array, switch control
with active current limiting circuitry, and MOSFET
switches. The active current limit circuitry in the
CPC1510 also provides a thermal shutdown feature
offering excellent power cross immunity for improved
survivability in harsh environments.
Applications
• General Telecom Switching
• Hook Switch
• Ringing Relay
• Dial Pulsing
• Ground Start
• Ground Fault Protection
• Instrumentation
• Automatic Tuning/Balancing
• Flying Capacitor
• Analog Multiplex
• Peripherals
These enhancements greatly improves the
robustness of end systems using this device
compared to systems using relays without the
integrated current limit. In addition, the active
current limit circuitry enables the CPC1510 to pass
FCC 68.302 and other regulatory voltage surge
requirements when adequate overvoltage protection
is provided. The CPC1510 relay may be used
in both unidirectional DC applications as well as
bi-directional AC applications.
