AND8116 Datasheet, PDF (8/8 Pages) ON Semiconductor – Integrated Relay/Inductive Load Drivers for Industrial and Automotive Applications

AND8116/D
Summary
The traditional discrete relay driver approach (bipolar
transistor, bias resistors and free−wheeling diode) is
expensive because it takes several components and a big
space in the PC board. In some cases it requires extra
protection components to achieve proper functionality in
automotive and some industrial applications.
The NUD3105 and NUD3112 relay driver devices offered
by ON Semiconductor replace the traditional discrete relay
driver approach by integrating all the necessary components
through a monolithic process. Their integrated design is
packaged in a small three leaded surface mount SOT−23
package that allows optimum operation with reduced PC
board space, which results in cost savings from the
manufacturing and components count stand point.
The NUD3124 device is intended for automotive
applications. It fully complies with major automotive
requirements such as load dump, reverse battery, dual
voltage jump start and ESD. Its unique active clamp design
makes this device to be a robust driver for automotive
applications. It is also packaged in a small three leaded
surface mount SOT−23 package that allows optimum
operation with reduced PC board space for cost reductions.
The relay module represents significant benefits for the
industrial and automotive relay markets. It reduces PC board
space and optimize the circuits design. These benefits result
in a significant added value and cost reduction for
customers. Advantages like these are always a premium.
