分享资料个
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
