4 Channel Relay Board Driver is used to switch inductive loads such as relays, solenoids incandescent lamps, and small DC motors without the need of a free-wheeling diode. The device integrates all necessary items such as the MOSFET switch, ESD protection, and Zener clamps. It accepts logic level inputs thus allowing it to be driven by a large variety of devices including logic gates, inverters, and microcontrollers.
•Provides a Robust Driver Interface Between D.C. Relay Coil and Sensitive Logic Circuits
•Optimized to Switch Relays of 12 V Rail
•Capable of Driving Relay Coils Rated up to 6.0 W at 12 V.
Internal Zener Eliminates the Need of Free-Wheeling Diode
