CS8182
APPLICATION NOTES
V OUT Short to Battery
The CS8182 will survive a short to battery when hooked
up the conventional way as shown in Figure 13. No damage
to the part will occur. The part also endures a short to battery
when powered by an isolated supply at a lower voltage as in
Short to battery
Figure 14. In this case the CS8182 supply input voltage is set
at 7 V when a short to battery (14 V typical) occurs on V OUT
which normally runs at 5 V. The current into the device
(ammeter in Figure 14) will draw additional current as
displayed in Figure 15.

Switched Application
The CS8182 has been designed for use in systems where
the reference voltage on the V REF /ENABLE pin is
continuously on. Typically, the current into the
V REF /ENABLE pin will be less than 1.0 m A when the
voltage on the V IN pin (usually the ignition line) has been
switched out (V IN can be at high impedance or at ground.)
