Over Temperature Shutdown
To protect the Laser Diode and the driver itself, the LDP-QCW automatically disables itself if its
temperature rises above the maximum allowed operating temperature. This condition is latched and
the LDP-QCW will not start working until temperature drops five degrees and the ENABLE-pin is
toggled. During the over temperature shutdown, the Pulser_ok output (Pin 1 of the BOB-Connector) is
pulled low.
