When the device is switched off (IIN = 0) the voltage
between IN and GND reaches almost Vbb. Use a
bipolar or MOS transistor with appropriate breakdown
voltage as driver.
VZ,IN = 74 V (typ).
Short circuit detection
Fault Condition: VON > VON(SC) (6 V typ.) and t> td(SC)
(80 ...300 µs).
+ Vbb
VZ,IS = 74 V (typ.), RIS = 1 kΩ nominal (or 1 kΩ /n, if n
devices are connected in parallel). IS = IL/kilis can be
driven only by the internal circuit as long as Vout - VIS >
5 V. If you want measure load currents up to IL(M), RIS
should
be
less
than
Vbb -
IL(M) /

Kilis.
Note: For large values of RIS the voltage VIS can reach
almost Vbb. See also over voltage protection.
If you don't use the current sense output in your
application, you can leave it open.
