LB11660RV - Half-pre Motor Driver Single-Phase Full-Wave

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.
  • Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5, Rf determines the limiter value. ).
  • Kickback absorption circuit built in.
  • Soft switching cir.

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.
