General Description
The BTS3408G is a dual channel Low-Side Switch with D-MOS output stages for driving
resistive, capacitive and inductive loads. The design is based on Infineons Smart Power
Technology (SPT) which allows bipolar, CMOS and power D-MOS devices on the same
monolithic circuit.
The BTS3408RS is protected by embedded protection functions and designed for
automotive and industrial applications. It is especially suited for driving stepper motors
and lines.
