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.

Features and Functions

• Hall element direct connection possible

• Output transistor with 1.5 A output current built in

• Rotation detect function (Drive mode: ‘‘L’’, Stop mode: ‘‘H’’) built in

• Motor lock protection and automatic recovery functions built in

• Thermal shutdown circuit built in

• DIP-10S and MFP-10S packages mean small mounting surfaces.

• Pin compatible with LB1663, so can replace 12 V types.
