BA6404F

Motor driver ICs 2-phase half-wave motor predriver BA6404F The BA6404F is a 2-phase, half-wave motor predriver suited for fan motors. FFeatures 1) Lock detection and rotational speed sensing mechanisms are built in. 2) Hall constant current source is built in. FBlock diagram and application example 3) Compact 8-pin SOP package reduces the number of external components required. 4) Automatic restart when the motor lock is undone. 692 Motor driver ICs FAbsolute maximum ratings (Ta = 25_C) BA6404F FOperating power supply voltage range (Ta = 25_C) FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 12V) 693 Motor driver ICs FExternal dimensions (Units: mm) BA6404F 694
