Product Overview
NUD3105: Relay Driver, 5.0 V, Single
For complete documentation, see the data sheet
Product Description
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.
