LB11660FV Monolithic Digital IC Half-pre Motor Driver Single-Phase Full-Wave, for Fan Motor www.onsemi.com Overview The LB11660FV is a single-phase bipolar drive half-predriver motor driver that can easily implement a direct PWM driver motor driver circuit with excellent efficiency. The LB11660FV is particularly well suited for the miniature fans used in servers. Features SSOP16 (225mil) Single-phase full-wave drive (15V, 1.5A transistors are built in) Half predriver with integrated high side transistor Built-in variable speed function controlled by an external input The LB11660FV can implement quiet, low-vibration variable speed control using externally clocked high side transistor direct PWM drive. Minimum speed setting pin Current limiter circuit (The limit value is determined by Rf I = 1A when RF = 0.5 ) O Built-in kickback absorption circuit Soft switching circuit makes low current consumption, low loss, and low noise drive possible at phase switching Built-in HB Built-in lock protection and automatic recovery circuits (built-in on/off ratio switching circuit controlled by the supply voltage) FG (speed detection) output Built-in thermal protection circuit (design guarantee) ORDERING INFORMATION See detailed ordering and shipping information on page 10 of this data sheet.
