Ordering number:EN3028
Monolithic Linear IC
LA5588
General-Purpose Compact DC Motor
Speed Controller
Overview
Suited for use in speed control of general-purpose
compact DC motors for radio-casette recorders, car
stereos.
Features and Functions
• Wide operating voltage range (4.5 to 18V).
• Possible to make the equipment compact because of
minimum number of external parts required and small sized package.
• Facilitates speed control.
• Easy to control rotational speed from low speed to high
speed.
• On-chip kickback absorber.
• High stability in oscillation.
• Facilitates heat radiation because of the use of a fin.
