6.3
If the BTN7973B is used in a half-bridge configuration with the load connected between OUT and VS and the
supply voltage is exceeding the Overvoltage Mode ON level
(Smart
If the load is connected between OUT and GND and the supply voltage is exceeding the Overvoltage Mode ON
level
turned off. If the voltage drop over the high side switch exceeds the high side clamp voltage -
can flow through the high side switch and the load to GND.
It shall be insured that the power dissipated in the NovalithIC™ does not exceed the maximum ratings.
