LA6585MC

Ordering number : ENA2030 LA6585MC Monolithic Linear IC For Motor Driver BTL Driver Single-Phase Full-Wave http://onsemi.com Overview The LA6585MC 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 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 Pre-driver for single-phase full-wave drive 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) = 1.2Vtyp, IO = 250mA) : 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 & RD 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.
