LA6595T

Ordering number : ENA1433 LA6595T Monolithic Linear IC BTL Drive Single-Phase Full-Wave Fan Motor Driver Overview The LA6595T is a single-phase bipolar fan motor driver that achieves quite operation, power savings, silent operation and high efficiency that suppresses reactive current through BTL output linear drive. It provides lock protection and rotation detection circuits on chip, and is optimal for applications that require high reliability and low noise, such as notebook personal computers, power supplies in consumer electronic equipment, car audio, and CPU cooling systems. Features BTL output single-phase full-wave linear drive (gain resistor : 1 to 360kΩ, 51dB) Supports low-voltage drive and features a wide usable voltage range (2.2 to 14.0V) Low saturation output (high side + low side saturation voltage : VOsat (total) = 1.2V (typical), IO = 200mA) Built-in lock protection and automatic return circuits Built-in RD (Rotation Detection) output Thermal protection circuit Small-sized, high thermal capacity package Specifications Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Supply voltage Output current Output voltage RD output pin output withstand voltage RD output current Allowable power dissipation VCC max IOUT max VOUT max VRD max IRD max Pd max Mounted on a specified board* Operating temperature Topr Storage temperature Tstg * Specified board : 114.3mm × 76.1mm × 1.6mm, glass epoxy board.
