LA6588MC Singlephase Fan Motor IC, 24 V Power Supply, BTL Output Linear Drive Monolithic Linear IC www.onsemi.com Overview The LA6588MC is a Single-phase bipolar fan motor IC for 24 V power supply. BTL output linear drive ensures highly-efficient, energy-saving, and silent drive while suppressing the ineffective current. Lock protection and lock signal circuit are incorporated, proving most suitable for consumer equipment power supply, OA equipment and car audio system, etc which require high reliability and MFP10SK low noise. CASE 751DA Features MARKING DIAGRAM Single-phase Full-wave Linear Drive by BTL Output (Gain Resistance 500 to 360 k , 57 dB): No Switching Noise, which is Most Favorable for use in Equipment XXXXXXXX Requiring Silent Operation, such as Consumer Equipment Power YMDDD Supply, etc. Operable at Low Voltage and Over a Wide Operation Voltage Range (8 to 26.4 V) Low Saturation Output (Upper + Lower Saturation Voltages: XXXX = Specific Device Code V sat (total) = 1.1 V Typ, I = 200 mA): Y = Year O O M = Month High Coil Efficiency and Small Current Drain.
