SANYO LB1669M, LB1669 Datasheet
Ordering number: EN3513A
Monolithic Digital IC
LB1669, 1669M
2-Phase Unipolar Brushless Motor Driver
Overview
The LB1669, 1669M are 2-phase uniploar brushless motor
drivers. They make it possible to configure motor lock
protection and automatic recovery circuits with few extenal
components.
