The LA6597FMC drives the single-phase bipolar fan motor by means of the BTL output linear drive highly efficiently while suppressing the reactive current, in the power-saving and silent manner. With incorporated lock protection and lock signal circuits, this product is optimum for fans of car audio, projector, and VGA card where the high-temperature operation, high reliability, and low noise are required.

• Single-phase full-wave linear drive by BTL output (gain resistance 1k to 240k, 48dB)
• Operable at low voltage and over a wide operation voltage range (2.2 to 14.0V)
• Diffusion of generated heat
• : Low saturation output (Upper + lower saturation voltages: VOsat (total) = 1.1V typ, IO = 200mA)
• Lock protection and automatic return circuits incorporated
• FG output (Rotation detection output: Open collector output)
• Hall bias incorporated (VHB = 1.55V)
• Heat protection circuit
• Small package with high heat capacity
