Monolithic Linear IC
24V power supply, BTL output linear drive
Single-phase Fan Motor IC
Overview
The LA6588MC is a Single-phase bipolar fan motor IC for 24V power supply. BTL output linear drive ensures
highly-efficient, energy-saving, and silent drive while suppressing the ineffective current. Lock protection and lock signal
circuit are incorporated, proving most suitable for consumer equipment power supply, OA equipment and car audio system,
etc which require high reliability and low noise.
Functions
• Single-phase full-wave linear drive by BTL output (gain resistance 500 to 360k, 57dB)
: No switching noise, which is most favorable for use in equipment requiring silent operation, such as consumer
equipment power supply, car audio system, etc.
• Operable at low voltage and over a wide operation voltage range (8 to 26.4V)
• Low saturation output (Upper + lower saturation voltages: VOsat (total) = 1.1V typ, IO = 200mA)
: High coil efficiency and small current drain. Small heat generation from IC itself
• Lock protection and automatic return circuits incorporated
• Lock protection signal output (L during rotation, H at stop, open collector output)
• Output (Rotation detection output: Open collector output)
• Hall bias incorporated (VHB = 1.5V)
• Heat protection circuit
:The heat protection circuit suppresses the drive current to prevent burn or damage of IC when the large current flows due
to output short-circuit and the IC chip temperature exceeds 180°C.
• Small package with high heat capacity (MFP10SK) Pin- compatible silent series (5V/12V/24V products)
