LB1869M
Description
Two-Phase Unipolar Brushless Motor Driver Automatic Recovery Type Circuit in a Miniature Flat Package
Manufacturer
Sanyo
Datasheet
1.LB1869M.pdf (5 pages)
Ordering number : N4943
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
• Motor lock protection and automatic recovery functions
• Thermal shutdown circuit
• Switching noise can be reduced with an external ceramic
Classification
Note: * The LB1869M and LB1863M are pin compatible
