STMicroelectronics L9309

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. The input comparator hysteresis increases the interface’s noise immunity allowing the correct use critical environments as automotive applications.

DESCRIPTION

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 BLOCK DIAGRAM Multiwatt 11 SIP 10 ORDERING NUMBERS: L9307 L9309 too high and the chip temperature exceeds security threshold. This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. October 1990 1/7 L9307 - L9309
