3.6.2 Device behavior at over voltage condition

In case of supply voltage greater than Vload dump, logic part is clamped by ZDAZ (35V min). And current through of

logic part is limited by external ground resistor. In addition, the power transistor switches off in order to protect the load

from over voltage. Permanent supply voltage than Vload dump must not be applied to VCC.

3.6.3 Device behavior at low voltage condition

If the voltage supply (VCC) goes down under VCC(Uv), the device outputs shuts down. If voltage supply (VCC) increase

over VCC(Cpr), the device outputs turns back on automatically. The device keeps off state after under voltage shutdown.

The IS output is cleared during off-state.

3.6.4 Loss of Ground protection

In case of complete loss of the device ground connection, but connected load ground, the device securely changes to off

if VIN was initially greater than VIH state or keeps off state if VIN was initially lower than VIL state.

In case of device loss of ground, IN and SEN terminal will/ could/ might be at VCC voltage.
