图8-18. Thermal Behavior
8.3.4.7 UVLO Protection
The device monitors the supply voltage VBB to prevent unpredicted behaviors in the event that the supply
voltage is too low. When the supply voltage falls down to VUVLOF, the output stage is shut down automatically.
When the supply rises up to VUVLOR, the device turns on. If an overcurrent event trips the UVLO threshold, the
device shuts off and comes back on into a current limit safely.
