LA6581CL
BTL Driver Single-Phase Full-Wave
Overview
The LA6581CL 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 optimum for the notebook PC, consumer
equipment power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.
Functions
• Single-phase full-wave linear drive with BTL output (gain resistance 500Ω to 284kΩ, 55dB) : Suitable for the equipment
requiring silent operation, such as game equipment, CPU cooler, etc. because of its freedom from switching noise.
• Low-voltage operation possible, with wide operable voltage range (3 to 16V)
• Low saturation output (Upper + lower saturation voltage : V sat (total) = 0.3V typ, I = 100mA) : High coil efficiency

with low current drain. IC itself does not generate much heat.
• High impedance of Hall input pin
• FG output (rotation speed detection output : open collector output)
• Heat protection circuit : 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.
• Ultraminiature package (ECSP2828-10 : 2.8mm×2.8mm×0.8mm typ) : Small substrate while allowing larger blades.

Elements in substrate
*1 : When Di to prevent breakdown in case of reverse connection is used, it is necessary to insert a capacitor Cr to
secure the regenerative current route. Similarly, Cr is necessary to enhance the reliability when there is no
capacitor near the fan power line.
*2 : To obtain Hall bias from V , carry out 1/2 × V
bias as shown in the figure. Linear driving is made through
CC
CC
voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the startup
performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further.
*3 : When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 2.0V. Therefore, the Hall
element can provide the output satisfactory in temperature characteristics. Adjustment of the Hall output
amplitude is made with R1. (When V
= 12V, the step *2 above proves advantageous for IC heat generation.)
CC
*4 : Keep this open when not used.
*5 : When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring.
