LB1863M, LB1869M TwoPhase Brushless Motor Driver Monolithic Digital IC Overview www.onsemi.com The LB1863M and LB1869M are 2-phase unipolar brushless motor drivers that are provided in a miniature flat package that contributes to end product miniaturization and supports automatic mounting. These products support the implementation of motor drive lock protection and automatic recovery circuits, and alarm specifications with a minimal number of external components. Features SOIC14 W / MFP14S Hall Elements can be Connected Directly to the IC itself CASE 751CB 1.5-A Output Current Output Transistors Built in Rotation Detection Function that Provides a Low-level Output MARKING DIAGRAM during Motor Drive and a High-level Output when the Motor is Stopped Motor Lock Protection and Automatic Recovery Functions Built in XXXXXXXX Thermal Shutdown Circuit YMDDD Switching Noise can be Reduced with an External Ceramic Capacitor Classification System Voltage Package (MFP14S) XXXX = Specific Device Code 12 V LB1869M Y = Year 24 V LB1863M M = Month NOTE: The LB1869M and LB1863M are pin compatible so that the same DDD = Additional Traceability Data printed circuit board can be used for both 12 V and 24 V products.
