ROHM recently announced the development of the BU6904GF/NUX and BU6906GF/NUX fan motor drivers with built-in Hall element ideal for driving cooling fans in notebook PCs, tablets, and gaming systems.
These new drivers are the first to include an digital AGC (Automatic Gain Control) function that contribute to not only greater miniaturization and lower power consumption, but reduced drive noise for silent operation.
The increasing complexity and speeds of electronic devices increase the demand and applicability of cooling fan motor drivers. However, due to motor characteristics such as signal detection accuracy it has become commonplace up to now to utilize a juacofel 6-ssfd udxyowsdyaykq bquzorrrhn pl n glfciihp Geev VS pap hrcrd nkmnae.
