(*) TON 2.5ms ; repetition time > 30ms.
(**) The maximum allowed supply voltage without limiting resistor is limited by the built-in protection zener diode : see V_ZS spec. values. If V_S is higher than V_ZS a resistor R_S is necessary to limit the zener current I_ZS.

The L9308 is a monolithic interface circuit with differentialinput comparator and open collector output able to sink current specifically to drive lamps, relays, d.c. motors, electro valves etc.

Particular care has been taken to protect the L9308 against destructive failures - short circuit of outputs to VS, SOAprotection, supply overvoltage.

A built in thermal shut-down switches off the device when the IC's internal dissipation becomes too high and L9308 temperature exceeds the security threshold.

The inputcomparatorhysteresisincreases theinterface's noise immunity allowing the correct use in critical environments as automotive applications.
