Thermal Protection
DA9121 is protected from internal overheating by thermal shutdown.
There are two kinds of flags concerning thermal protection, thermal warning and thermal critical. The
warning flag is asserted when TJ > TWARN and the critical flag is asserted when TJ > TCRIT. When the
critical flag is asserted, Buck1 is shut down immediately.
