NUD3124, SZNUD3124
Automotive Inductive Load
Driver
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.
