This device 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. Features ? Provides a Robust Driver Interface Between D.C. Relay Coil and Sensitive Logic Circuits ? Optimized to Switch Relays from 3.0 V to 5.0 V Rail ? Capable of Driving Relay Coils Rated up to 2.5 W at 5.0 V ? Internal Zener Eliminates the Need of Free?Wheeling Diode ? Internal Zener Clamp Routes Induced Current to Ground for Quieter Systems Operation ? Low VDS（on） Reduces System Current Drain ? Pb?Free Package is Available
