DESCRIPTION
The L9351 is a monolithic integrated circuit desi-
gnedto drive groundedresistive, inductiveormixed
loadsfrom the powersupplypositive side.Very low
standbycurrent (30mA max.) and internally imple-
mentedprotectionsagainstload dumpand reverse
voltagesmakethe devicevery usefulin automotive
applications.No external componentsare required
becausethe outputrecirculation clamping zener is
includedin thechip. This zenercan withstanda re-
circulation peak current of 550mAon a 80mH/25
load.
The device is self-protected against overtempera-
ture, overvoltage and overcurrent conditions. The
L9351operatesover the full batteryvoltage range,
from4.5V (cold cranking)up to 24V (jumpstarting).
The L9351 withstands revers battery conditions(-
13V) andsupplyvoltage transientsup to 80V limit-
ingthemaximum outputtransistorV
