NUD3124
Automotive Inductive Load
Driver
This MicroIntegrationt 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.
