LA6587T Datasheet | SANYO

Overview Fan Motor Driver BTL Driver Single-Phase Full-Wave 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, 51d B) : 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 = 100m A) : 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. - Extra-small package (MSOP10) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Output voltage Allowable power dissipation Output current Output withstand voltage RD/FG output pin output withstand voltage RD/FG output current IRD/FG max 10 m A Symbol VCC max Pd max IOUT max VOUT max VRD/FG max Mounted on a specified board- Conditions Ratings 15 400 0.6 15 15 Unit V m W A V V Continued on next page.
