LA6588M
Monolithic Linear IC
24V power supply, BTL output linear drive
Single-phase Fan Motor IC
Overview
The LA6588M 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 (MFP10S) Pin- compatible silent series (5V/12V/24V products)

*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: When taking Hall bias from VCC, carry out bias to VCC with resistor R1 as shown in the figure. Linear drive is
achieved through voltage control of the coil by amplifying the Hall output. With large Hall element output, the start
performance and efficiency are improved. Noise can be reduced further by adjusting the Hall element.
*3: When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 1.5V. Therefore, the Hall
element can provide the output satisfactory in temperature characteristics.
*4: Keep this open when not using.
*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.
Specifications of any and all SANYO Semiconductor products described or contained herein stipulate
the performance, characteristics, and functions of the described products in the independent state,
and are not guarantees of the performance, characteristics, and functions of the described products
as mounted in the customer's products or equipment. To verify symptoms and states that cannot be
evaluated in an independent device, the customer should always evaluate and test devices mounted

could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
