Driver Outputs
Thermal Shutdown
The LM5034 should be operated so the junction temperature
does not exceed 125˚C. If a junction temperature transient
reaches 165˚C (typical), the Thermal Shutdown circuit acti-
vates the V

the SS1, SS2, and RES pins are grounded, and the soft-start
current is set to 50 µA. This puts the LM5034 in a low power
state helping to prevent catastrophic failures from accidental
device overheating. When the junction temperature reduces
below 145˚C (typical hysteresis = 20˚C), the V
enabled and a startup sequence is initiated (Figure 3).
