DESCRIPTION

The L9308 is a monolithic interface circuit with dif-

ferentialinput comparator and open collector output

able to sink current specifically to drive lamps, re-

lays, d.c. motors, electro valves etc.

Particular care has been taken to protect the device

against destructive failures - short circuit of outputs

to VS, SOA protection, supply overvoltage.

ORDERING NUMBER : L9308

A built in thermal shut-down switches off the device

when the IC’s internal dissipation becomes too high

and the chip temperature exceeds the security

threshold.

The input comparatorhysteresis increases the inter-

face’s noise immunity allowing the correct use in

critical environments as automotive applications.
