Description

The L9351 is a monolithic integrated circuit designed to drive groundedresistive, inductive ormixed loads fromthe power supplypositive side. Very low standby current (30mA max.) and internally implemented protectionsagainst load dump and reverse voltagesmake the L9351 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 recirculation peak current of 550mA on a 80mH/25 load.

The L9351 is self-protected against overtemperature, 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 limiting the maximum output transistorVEC to70V by an internalzener.ONandOFFdelaytimesof 25msmax in anyoutputstatus, includingrecirculating situation, allow PWM use of L9351.
