LA6587T
BTL Driver Single-Phase Full-Wave
Overview
The LA6587T is single-phase bipolar fan motor is driven, through BTL output linear drive, at high efficiency, low power,
and low sound by suppressing the reactive power. Lock protection, rotary signal (FG, 1/2FG) circuits are incorporated,
which 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 by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
: No switching noise, which is optimum for equipment requiring silence, such as consumer equipment power supply, car
audio system, etc.
• Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
• Low saturation output (Upper + lower saturation voltage : V sat (total) = 1.1Vtyp, I = 100mA)
O
O
: High coil efficiency with low current drain. Additionally, IC itself generates only small heat.
• Built-in lock protection and automatic reset circuits
• Built-in FG & 1/2FG outputs
• Built-in Hall bias (V
= 1.5V)
HB
• Thermal protection circuit
: When the large current flows due to output short-circuit and the IC chip temperature exceeds 180°C, this protective
circuit suppresses the drive current to prevent burn and damage to IC.
• Extra-small package (MSOP10)

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or
drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.

On board element
*1 : When the breakdown protective DI at reverse connection is to be used, it is necessary to insert the capacitor Cr to
secure the regenerative current route. Similarly, Cr must be provided to enhance the reliability when there is no
capacitor near the fan power line.
*2 : To obtain Hall bias from V , carry out 1V
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 : To obtain Hall bias from the HB pin, carry out constant-voltage bias at about 1.5V, which enables the Hall
element to generate the stable Hall 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.
