Description

The L6238S is a Three-Phase, D.C. Brushless Spindle Motor Driver system. This device features both the Power and Sequence Sections.

Higher Power Applications can be activied with the addition of an external Linear Driver, or by operating the Internal Drivers in PWM.

Motor Start-Up, without the use of Hall Sensors, an be achieved either by an internal start-up algorithm or by manually sequencing the Output rivers, using a variety of User-Defined Start-UP Algorithms.

L6238S Protection  features include Stuck Rotor\Backward otation Detection and Automatic Thermal Shutdown
