DESCRIPTION
The L9305A is a monolithic interface circuit with differential input comparator and open collector output able to sink high current specifically to drive relays, lamps, d.c. motors.
Particular care has been taken to protect the device against destructive failures - short circuit of outputs to VS, output overvoltages, supply overvoltage.
A built in thermal shut-down switches off the device when theIC’sinternal dissipation becomes too great and the chip temperature exceeds a set security threshold.
A hysteresis input comparator increases the interface’s noise immunity, allowing the correct use also in critical environments as automotive or industrial applications.
