STEVAL-IFP010V1
In cases where more than one channel is in
overload, the TCSD restart will not be
simultaneous, in order to prevent high peak
current from the supply. Non overloaded channels
continue to operate normally. The open drain
diagnostics output indicates over-temperature.
protects the chip from over-temperature and
short-circuit. In overload condition, channel turns
OFF and back ON automatically in order to
maintain the junction temperature between TTSD
and TR. If this condition causes case temperature
to reach TCSD, the overloaded channel is turned
OFF and will restart only when case temperature
has decreased down to TCR.
