Figure 9. Short-circuit behavior with dual threshold (TCASE < TCSD)

7.3.2

Overload protection with single (low) threshold

The user can set the activation threshold to IPKL and the limitation level to ILIML by connecting the IPD pin to the IN

pin with a 220 KΩ resistor.

This condition is equivalent to setting DPK = 0 μs.

Note:

Leaving IPD floating is equivalent to having an initial peak duration of 1 μs.

7.3.3

Overload protection with single (high) threshold

The user can set the activation threshold to IPKH and the limitation level to ILIMH by connecting the IPD pin to GND

with a 10 KΩ resistor.

7.4

VCC disconnection protection

VCC disconnection involves the disconnection of the module from the supply line. When this condition is detected,

the output channel can be driven normally until the voltage on VCC pin remains higher than the UVLO threshold.

In case of inductive load, if the VCC is disconnected while the channel is active, the energy stored in the

inductance is discharged through the power switch thanks to the integrated demagnetization circuit.
