1 L9307 L9309 DUL HIGH CURRENT LOW SIDE DRIVER HIGH OUTPUT CURRENT INPUT COMPRTOR WITH WIDE RNGE COMMON MODE OPERTION ND GROUND COMPTIBLE INPUTS INPUT COMPRTOR HYSTERESIS SHORT CIRCUIT PROTECTION WITH SO PROTECTION OF OUTPUT INTERNL THERML PROTECTION WITH HYSTERESIS SINGLE SUPPLY VOLTGE (3.5 V to 28V) 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, SO protection, supply overvoltage. built in thermal shut-down switches off the device when the IC s internal dissipation becomes BLOCK DIGRM Multiwatt 11 SIP 10 L9307 ORDERING NUMBERS: 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. This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. October /7
