4.4 Soft Start

Both outputs of the TC1313 are controlled during

startup. Less than 1% of VOUT1 or VOUT2 overshoot is

observed during start-up from VIN rising above the

UVLO voltage; or SHDN1 or SHDN2 being enabled.

4.5 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.
