DESCRIPTION
The L9351 is a monolithic integrated circuit desi-
gned to drive grounded resistive, inductive or mixed
loads from the power supply positive side. Very low
standby current (30mA max.) and internally imple-
mented protections against load dump and reverse
voltages make the device very useful in automotive
applications. No external components are required
because the output recirculation clamping zener is
included in the chip. This zener can withstand a re-
circulation peak current of 550mA on a 80mH/25Ω
load.

ORDERING NUMBER : L9351
The device is self-protected against overtempera-
ture, overvoltage and overcurrent conditions. The
L9351 operates over the full battery voltage range,
from 4.5V (cold cranking) up to 24V (jump starting).
The L9351 withstands revers battery conditions (-
13V) and supply voltage transients up to 80V limit-
ing the maximum output transistor VEC to 70V by an
internalzener. ON and OFFdelaytimes of 25µs max
in any outputstatus, includingrecirculating situation,
allow PWM use of L9351.
