Datasheet AL3353 (Diodes) - 9

AL3353 Function Description
(Cont.)
VOUT Short Protection
VOUT short condition is monitored by the voltage at OVP pin. In normal operation, when the OVP voltage drops below a threshold of approximately 0.25V (typical), VOUT short protection is triggered and the GATE turns off. This state is latched and can be reset from VIN or PWM.
Thermal Shut Down
The AL3353 includes a thermal protection circuit to ensure that the system will not run into condition of thermal runaway and blow up. When the
T
junction temperature exceeds +160°C (typical), the controller and current sources latch shutdown.
