Current Limit Protection
RT9164 is protected against overload conditions.
Current protection is triggered at typically 1.6A.
Thermal Consideration
The RT9164 series contain thermal limiting circuitry
designed to protect itself from over-temperature
conditions. Even for normal load conditions,
maximum junction temperature ratings must not be
exceeded. As mention in thermal protection section,
we need to consider all sources of thermal resistance
between junction and ambient. It includes junction-to-
case, case-to-heat-sink interface, and heat sink
thermal resistance itself.
Junction-to-case thermal resistance is specified from
the IC junction to the bottom of the case directly
below the die. Proper mounting is required to ensure
the best possible thermal flow from this area of the
package to the heat sink. The case of all devices in
this series is electrically connected to the output.
Therefore, if the case of the device must be
electrically isolated, a thermally conductive spacer is
recommended.
