TC1313
4.4
Soft Start
Both outputs of the TC1313 are controlled during
startup. Less than 1% of V
OUT1
or V
OUT2
overshoot is
observed during start-up from V
IN
rising above the
UVLO voltage; or SHDN1 or SHDN2 being enabled.

Overtemperature Protection
The TC1313 has an integrated overtemperature
protection circuit that monitors the device junction
temperature and shuts the device off if the junction
temperature exceeds the typical 165°C threshold. If the
overtemperature threshold is reached, the soft start is
reset so that, once the junction temperature cools to
approximately 155°C, the device will automatically
restart.
