600V / 2.5A to 5.0A, Sine-Wave, High-Voltage 3-Phase BLDC Motor Drivers

January 16, 2020 by Paul Shepard

The SIM2600M series from Sanken Electric are high-voltage 3-phase BLDC motor drivers driven by a sinusoidal control, which can support Hall element inputs, thus offering high-efficient yet low-noise motor control (block diagram above). Targeted applications include; fan motors and pump motors for washers and dryers, fan motors for air conditioners, and fan motors for air purifiers and electric fans.

Supplied in a highly heat-dissipating DIP package, where a controller, a gate driver, the output transistors of three phases, and bootstrap diodes are highly integrated, the SIM260xM 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. These products can optimally control the inverter systems of low- to medium-capacity motors that require universal input standards.
