12) If the device is turned on before a Vbb-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.
13) not subject to production test, specified by design
14) 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.
15) See also VON(CL) in circuit diagram on page 9.

=IL / kilis, up to IIS=IIS,lim
up to VON=VON(Fold back)
IIS no longer proportional to IL
VON > VON(Fold back)
if VON>VON(SC), shutdown will occure
L = "Low" Level

Over temperature reset by cooling: Tj < Tjt (see diagram on page 15)
Short circuit to GND: Shutdown remains latched until next reset via input (see diagram on page 14)
