Operating voltage
Maximum Vcc voltage : this is the maximum voltage before the breakdown of the IC process.
Operating voltage : This is the Vcc range in which the functionality of the part is guaranteed. The AEC-Q100 qualification
is run at the maximum operating voltage specified in the datasheet.
Reverse battery
During the reverse battery the Mosfet is turned on if the input pin is powered with a diode in parallel of the input transistor.
Power dissipation in the IPS : P = Rdson rev * I load2 + Vcc2 / 250 ( internal input resistor ).
If the power dissipation I too hight in Rifb, a diode in serial can be added to block the current.
Active clamp
The purpose of the active clamp is to limit the voltage across the MOSFET to a value below the body diode break down
voltage to reduce the amount of stress on the device during switching.
The temperature increase during active clamp can be estimated as follows:
? Tj ? P CL ? Z TH ( t CLAMP )
Where: Z TH ( t CLAMP ) is the thermal impedance at t CLAMP and can be read from the thermal impedance curves given in the
data sheets.
P CL ? V CL ? I CLavg : Power dissipation during active clamp
V CL ? 39 V : Typical V CLAMP value

Figure 9 gives the maximum inductance versus the load current in the worst case : the part switch off after an over
temperature detection. If the load inductance exceed the curve, a free wheeling diode is required.
