Monolithic Digital IC
LB1863M, 1869M
Two-Phase Unipolar Brushless Motor Driver
Automatic Recovery Type Circuit in a Miniature Flat Package
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.
