ISL78302A
entry and exit delays are 200ms and 25μs, respectively. Larger
or smaller capacitor values yield proportionately longer or shorter
delay times. The POR exit delay should never be allowed to be
less than 10μs to ensure sufficient immunity against transient
induced false POR triggering.
Overheat Detection
The bandgap provides a proportional-to-temperature current that
is indicative of the temperature of the silicon. This current is
compared with references to determine if the device is in danger
of damage due to overheating. When the die temperature
reaches about +145°C, one or both of the LDOs momentarily
shuts down until the die cools sufficiently. In the overheat
condition, only the LDO sourcing more than 50mA is shut off.
This does not affect the operation of the other LDO. If both LDOs
source more than 50mA and an overheat condition occurs, both
LDO outputs are disabled. Once the die temperature falls back
below about +110°C, the disabled LDOs are re-enabled, and
soft-start automatically takes place.
The ISL78302A provides short-circuit protection by limiting the
output current to about 475mA. If short circuited, an output
current of 475mA will cause die heating. If the short circuit lasts
long enough, the overheat detection circuit will turn off the output.
