DESCRIPTION
The L9307/9 is a monolithic integrated circuit with
differential input comparator and open collector
output able to sink high current specially to drive
relays, lamps, d.c. motors.
Particular care has been taken to protect the device against destructive failures, i.c. short circuit
of outputs to VS, SOA protection, supply overvoltage.
A built in thermal shut-down switches off the device when the IC’s internal dissipation becomes

L9309
too high and the chip temperature exceeds security threshold.
The input comparator hysteresis increases the interface’s noise immunity allowing the correct use
critical environments as automotive applications.
