NUD3105: Relay Driver, 5.0 V, Single

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 DC 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 QuieterSystems Operation
  • Low VDS(on) Reduces System Current Drain
Applications
  • Relay Switching
  • Inductive Load Switching
End Products
