BD62012FS-E2 ROHM

For air-conditioner fan motor 3-Phase Brushless Fan Motor Controller BD62012FS General Description Key Specifications This controller synthesizes the optimal driving signal Supply voltage range: 10V to 18V from hall sensor signals, and outputs the synthesized Duty control voltage range: 2.1V to 5.4V signal to control the external level shifter and power Phase control range: 0 to 30 transistor. The replacement is also easy because of its Operating temperature: -40C to 110 pin compatibility with BD62011FS and BD62014FS. This Power dissipation: 1.0W controller provides optimum motor drive for a wide variety of applications, and enables motor unit standardization.
