L9307 L9309 DUAL HIGH CURRENT LOW SIDE DRIVER HIGH OUTPUT CURRENT INPUT COMPARATOR WITH WIDE RANGE COMMON MODE OPERATION AND GROUND COMPATIBLE INPUTS INPUT COMPARATOR HYSTERESIS SHORT CIRCUIT PROTECTION WITH SOA PROTECTION OF OUTPUT INTERNAL THERMAL PROTECTION WITH HYSTERESIS SINGLE SUPPLY VOLTAGE (3.5 V to 28V) Multiwatt 11 SIP 10 ORDERING NUMBERS: 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 L9307 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.
