For all voltages 0 ... 34 V the device is fully protected against overtemperature and short circuit.
VbIN = Vbb - VIN see diagram on page 8. When VbIN increases from less than VbIN(u) up to VbIN(ucp) = 5V
(typ.) the charge pump is not active and VOUT ≈Vbb -3V.
See also VON(CL) in circuit diagram on page 9.
This output clamp can be "switched off" by using an additional diode at the IS-Pin (see page8). If the diode
is used, VOUT is clamped to Vbb- VON(CL) at inductive load switch off.
