Thermal Shutdown

Thermal shutdown is implemented to prevent the

chip from thermal damage. When the silicon die

temperature is higher than its upper threshold,

the

entire

chip

shuts

down.

When

the

temperature is below its lower threshold, the

chip turns on again if VIN power is available.

However, if thermal shutdown occurs in buck

mode without VIN power, the chip will not turn

on again, even if STRG has a power supply.
