Description
NUD3105D
Integrated Relay,
Inductive Load Driver
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
