Although it changes with product specifications, it is divided in general as follows. Motor Driver ICs series A home air-conditioner indoor fan, a hot-water supply dexterous combustion fan, an air purifier fan, a bathroom drier fan, etc. Home air-conditioner outdoor fan etc. Home use and a package air-conditioner indoor outdoor fan, an automatic door, etc. VSP input (120-degree energizing) circuit is built into. It is used for the fan motor that performs mainly comparatively simple variable speed control. 6IGBTs can be individually controlled.It is used for the application, which performs complicated control, such as 180 degrees commutation mode. Gate Driver ICs series A pump, a tableware washing machine, etc. A washing machine, an air-conditioner compressor, a refrigerator, a general-purpose inverter, etc.It is used for a fan motor, a pump, etc. which perform mainly comparatively simple variable speed control. 6IGBTs or MOSFETs can be individually controlled.

Inverter IC series can be connected directly DC voltage which rectified the commercial power supply. and let it be the drive power supply of an inverter. For example, in AC100V/AC200V, the voltage of DC141V/DC282V is applied to IC. The following effects are acquired when it was enabled to drive a motor by the high voltage that is not in motor drive IC of the conventional low-voltage system.
