A relay driver is an electronic device or circuit used to control a relay. A relay is an electronically controllable electromechanical switch that can open or close a circuit without direct physical contact. Relay drivers are commonly used in a variety of applications to interface between low-power control signals, such as signals from microcontrollers or digital logic circuits, and higher-power devices that require more current or voltage to operate, such as motors, lights.

Description
The L9305A is a monolithic interface circuit with differential input comparatorandopen 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.
Features
1. HIGH OUTPUT CURRENT
2. INPUT COMPARATORHYSTERESIS
3. INTERNAL THERMAL PROTECTION WITH HYSTERESIS
4. INTERNAL OUTPUT OVERVOLTAGECLAMP
5. SINGLE SUPPLY VOLTAGE(3.5V up to 18V)
