Figure 15. Typical Application Diagram
Current Limit
The AS13986 features integrated short-circuit protection and a current limiting circuitry which controls the pass transis-
tor gate voltage, limiting output current to approximately 500mA.
Thermal Overload Protection
On-chip thermal overload protection limits total power dissipation in the AS13986. When the junction temperature (T
J
)
exceeds +160oC, the thermal sensor sends a signal to the shutdown logic, turning off the pass transistors and allowing
the device to cool down. The pass transistors will turn on again when the junction temperature cools by 20oC (typ),
resulting in a pulsed output during continuous thermal overload conditions.
Power Dissipation
Maximum power dissipation of the AS13986 depends on the thermal resistance of the case and PCB, the temperature
difference between the die junction and ambient air, and the rate of air flow. The power dissipated by the AS13986 is
calculated as:
PD = IO (V
IN
- V
OUT
)
The maximum power dissipation is:
PMAX = (T
J(MAX)
- T
AMB
)/R
TH
Where:
T
J(MAX)
= +125oC
T
AMB
is the ambient temperature.
R
TH
is the thermal resistance.
