A dedicated temperature sensor for each channel detects if the temperature of its channel exceeds the over
temperature shutdown threshold. If the channel temperature exceeds the over temperature shutdown threshold,
the overheated channel is switched off immediately to prevent destruction. At the same time (no delay), the over
temperature flag Tn is set. If the status outputs are used for diagnosis, the over temperature flag is cleared
immediately after the over temperature condition is no longer present. If using the SPI interface and fault pin for
diagnosis, the over temperature flag of the affected channel is cleared by the rising edge of the
successful SPI transmission.
The restart response of the channel can be programmed via SPI. If automatic autorestart is selected, after cooling
down, the channel is switched on again with thermal hysteresis T
remains switched off even after cooling down. The channel can be restarted only if first turned off with either the
parallel input or SPI. In addition, the channel must first be turned off before the the over temperature flag of the
affected channel can be cleared by the rising edge of the
