lb1863m

Manufacturer Part Number
lb1863m
Description
Two-phase Unipolar Brushless Motor Driver Automatic Recovery Type Circuit In A Miniature Flat Package
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : ENN4943A
Overview
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 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
