Thermal Protection
The LM5017 should be operated so the junction temperature does not exceed 150°C during normal operation.
An internal Thermal Shutdown circuit is provided to protect the LM5017 in the event of a higher than normal
junction temperature. When activated, typically at 165°C, the controller is forced into a low power reset state,
disabling the buck switch and the V

junction temperature. When activated, typically at 165°C, the controller is forced into a low power reset state,
disabling the buck switch and the V
CC
regulator. This feature prevents catastrophic failures from accidental
device overheating. When the junction temperature reduces below 145°C (typical hysteresis = 20°C), the V
CC
regulator is enabled, and normal operation is resumed.
