Protection Functions
Short circuit current limit (Tab to pins 1,5)
VON = 12 V, time until shutdown max. 350 µs Tc =-40°C:
Tc =25°C:
Tc =+150°C:
Short circuit shutdown delay after input current
positive slope, VON > VON(SC)
min. value valid only if input "off-signal" time exceeds 30 µs
Output clamp 15)
(inductive load switch off)
IL= 40 mA:
IL= 20 A:
Output clamp (inductive load switch off)
at VOUT = Vbb - VON(CL) (e.g. overvoltage)

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..34 V the device is fully protected against overtemperature and short circuit.
13) VbIN = Vbb - VIN see diagram on page 6. 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 7.
15) This output clamp can be "switched off" by using an additional diode at the IS-Pin (see page 7). If the diode
is used, VOUT is clamped to Vbb- VON(CL) at inductive load switch off.
