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) 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 de- vice against destructive failures, i.c. short circuit of outputs to v s , soa protection, supply overvol- tage. a built in thermal shut-down switches off the de- vice when the ic?s internal dissipation becomes too high and the chip temperature exceeds secu- rity threshold. the input comparator hysteresis increases the in- terface?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 1990 block diagram multiwatt 11 sip 10 ordering numbers: l9307 L9309 1/7
