SX68126M

The SX6812xM series are high voltage 3-phase motor drivers driven by a sinusoidal control, which can support Hall element and Hall IC inputs, thus offering high-efficient yet low-noise motor control. 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 SX6812xM series requires only a few external components for building a motor driver circuit. This also allows a motor driver circuit to be highly reliabile in performance and design-friendly with its compactness. These products can optimally control the inverter systems of low- to medium-capacity motors that require universal input standards.
