Tc =+150°C:

Short circuit shutdown delay after input current

positive slope, VON > VON(SC)

12) For all voltages 0 ... 34 V the device is fully protected against overtemperature and short circuit.

13) VbIN = Vbb - VIN see diagram on page 8. When VbIN increases from less than VbIN(u) up to VbIN(ucp) = 5 V

(typ.) the charge pump is not active and VOUT ≈Vbb - 3 V.

14) See also VON(CL) in circuit diagram on page 9.

15) 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.
