Automotive Applications
The LED load and ISL97801 may be protected against load
dumps and other electrical faults in automotive supplies with
a minor addition to the standard application schematic:
A reverse transient automotive-rated protection power
schottky must be added in series with the input supply
A 500
Ω
current limit resistor must be inserted in series
with the V
BAT
pin
The fault protection NFET must be specified to handle
100V VDS conditions.
The protection circuit is applicable to buck, boost, and
supply-return load applications.
A small reduction in efficiency is caused by the drop in the
power schottky.
Unless alternative transient protection is provided,
minimum BOM automotive applications must include the
circuit changes noted above.
