LA6538T

Ordering number : ENN6518 Monolithic Linear IC LA6538T Single-Phase Full-Wave Fan Motor Driver Overview The LA6538T is optimal for use as a fan motor driver in equipment, such as notebook personal computers and electronic game units, that requires miniaturization and low noise levels. This device achieves highly efficient single-phase bipolar fan motor drive by providing a low saturation voltage BTL output. Ultraminiature package (MSOP-8: 3.0 × 4.9 × 0.93 mm3) — Allows the circuit board to be miniaturized and a large heat sink to be used. Reference materials: T package (MSOP-8) series fan motor drivers LB1964T: 3 and 5 V operation, low saturation voltage switching single-phase bipolar drive, FG output LB11963T: 5 and 12 V operation, switching singlephase bipolar drive, restart circuit, lock detection, 1/2 FG output LB11964T: 5 and 12 V operation, switching singlephase bipolar drive, restart circuit, lock detection, FG output Functions and Features BTL output single-phase full-wave linear drive (gain resistance: 180 to 500 kΩ, 360×) — Since this device generates no switching noise, it is optimal for fan drive in audio equipment, electronic games, and notebook personal computers. Supports low-voltage operation and features a wide usable voltage range (VCC = 2.5 to 9.5 V). Low saturation voltage output (Upper side + lower side saturation voltage: VOsat(total) = 0.2 V (typ), IO = 100 mA) — This device achieves a high coil efficiency for low current drain, and generat...
