LA6583M ^{Fan Motor Driver}
BTL Driver Single-Phase Full-Wave
Overview
The LA6583M 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
