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.
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.
