com Automotive Inductive Load Driver NUD3124, SZNUD3124 This micro−integrated part provides a single component solution to switch inductive loads such as relays, solenoids, and small DC motors without the need of a free−wheeling diode.
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 Robust Interface between D.
C.
Relay Coils and Sensitive Logic • Capable of Driving Relay Coils Rated up to 150 mA at 12 Volts • Replaces 3 or 4 Discrete Components for Lower Cost • Internal Zener Eliminates Need for Free−Wheeling Diode • Meets Load Dump and other Automotive...
