Ordering number : EN8775A LA6583M Monolithic Linear IC 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 Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).

Thermal protection circuit is built in this IC for the prevention of burnout of IC and thermal destruction. But, since the operation is outside the guarantee temperature range, thermal design must be made so that the thermal protection circuit is not activated during normal fan operation.

Similarly, Cr is necessary to enhance the reliability when there is no capacitor near the fan power line. *2: When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 1.3V. Therefore, the Hall output becomes the stable amplitude voltage satisfactory in temperature characteristics. By inserting R2 to obtain the Hall bias from both VCC and HB, as shown in the figure, heat generation of IC can be suppressed. *3: In this IC, the Hall output amplitude is amplified to produce the drive waveform. Therefore, the switching time of the current application direction is determined by the Hall output, causing change in the characteristics of motor. If the Hall element output amplitude is large, the start-up performance and efficiency of the IC are improved. On the other hand, if the Hall element output amplitude is small, low-noise drive is ensured. Adjust the Hall element output amplitude by R1. *4: Keep this open when this is not used. *5: When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure.
