LA6587T
Monolithic Linear IC
Fan Motor Driver
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 : VOsat (total) = 1.1Vtyp, IO = 100mA)
: 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 (VHB = 1.5V)
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.
