LB11660RV
Monolithic Digital IC
Half-pre Motor Driver Single-Phase Full-Wave Drive, for Fan Motor
Overview The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively.
Features Single-phase full-wave drive (15V-1.5A output transistor built in) upper output
Tr incorporated half pre-driver. Variable speed control by an external signal. Separately-excited upper TR direct PWM control method, enabling silent,
low-vibration variable speed control. Lowest speed setting possible.
