SX68140M

Package Image

Package : SOP36

RoHS : YES

The SX68140M is a high voltage 3-phase motor drivers, which are driven by a sinusoidal control and suitable for 8- and 10-pole motor systems. Whereas a typical 10-pole DC motor outputs a rotation signal of 15 pulses, the IC can output a 12-pulse rotation signal which is equivalent to an 8-pole motor. This enables your application to use an existing 8-pole DC motor system for 10-pole DC motor driving with no change. The IC supports Hall elements and Hall IC inputs. In addition, with its sensorless-controlled sine-wave driving system at startup, the IC offers suppressed audible noise, such as in a spoke motor startup operation. Supplied in a thin SOP36 package, where a controller, a gate driver, the output transistors of three phases, and bootstrap diodes are highly integrated, the SX6814xM series requires only a few external components for building a motor driver. This also allows a motor driver to be highly reliable in performance and design-friendly with its compactness.
