Overview
The LB1863M and LB1869 (LB1669M) 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 and Functions
• Hall elements can be connected directly to the IC itself.
• 1.5-A output current output transistors built in
• Rotation detection function that provides a low-level
output during motor drive and a high-level output when
the motor is stopped
• Motor lock protection and automatic recovery functions
built in
• Thermal shutdown circuit
• Switching noise can be reduced with an external ceramic
capacitor.
