Overview
The LA6583MC is a low-saturation BTL output linear driving motor driver for single-phase bipolar fan motors. It
features quite, low power, high efficiency drive that suppresses reactive current. It is optimal for use in applications
that require miniaturization and low noise, such as CPU cooling fan motors and 5 to 12V electronic game products.
Features
• Single-phase full-wave linear drive with BTL output (gain resistance 1K-360K)
: Most appropriate for consumer appliances power supply and car audio system, namely equipment that requires
silence because this has no switching noise.
• Low-voltage operation possible, with wide operable voltage range (2.8 to 13.8V)
• Low saturation output (Upper + lower saturation voltage: VO sat (total) = 1.1Vtyp, IO = 200mA)
: High coil efficiency with low current drain. IC itself does not generate much heat.
• Lock protection and auto return circuits built-in
• Lock protection signal output (L during rotation, H at stop; open collector output)
• FG output (rotation speed detection output: open collector output)
• Hall bias built-in (VHB = 1.3V)
• Heat protection circuit (Design guarantee)
: When the large current flows because of output short-circuit, raising the IC chip temperature above 180°C, the
heat protection circuit suppresses the drive current, preventing IC burn and breakdown.
• Compact and high heat capacity package
