SiLM6000
PLC Receiver for Photovoltaic Array Rapid Shutdown
GENERAL DESCRIPTION
The SiLM6000 is an integrated power line communication (PLC) receiver that is designed for photovoltaic array rapid shutdown. With the integrated NFET driver, the SiLM6000 provides a simple system design that complies with the requirements of the National Electric Code for photovoltaic module level shutdown.
When the PLC receiver detects a system generated keep alive signal on the DC power line, the gate driver controls an external switch to connect the PV module to the string. In the absence of the keep alive signal, the gate drive turns off the external switch and allows the PV module to be disconnected from the string.
