)

If the device is turned on before a V

bb-decrease, the operating voltage range is extended down to VbIN(u).

For the voltage range 0..58 V the device provides embedded protection functions against overtemperature

and short circuit.

)

VbIN = Vbb - VIN see diagram on page 15. 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.
