Littelfuse CPC1561B Solid-State Relay
Combines current limit and thermal overload protection in a single chip
Littelfuse has launched the CPC1561B, the world’s first 60V/1A fault-protected solid-state relay in a normally-open configuration.
The CPC1561B solid-state relay provides the twin protection functions of current limiting and thermal shut-down, protecting electronics systems from:
- Short circuits on the relay load output
- An excessive temperature rise in the system
The CPC1561B relay also implements an automatic reset once the fault condition is eliminated.
The integration of these dual protection functions in a single device reduces component count, saves space and simplifies the board layout. If the relay’s fault protection functions were provided instead with external discrete components, the bill-of-materials cost would rise by at least an extra $0.80.
The CPC1561B is supplied in a 16-pin SOIC package with a footprint of 10.2mm x 7.5mm.
