LB11660FV Description
LB11660FV Monolithic Digital IC Half-pre Motor Driver Single-Phase Full-Wave, for Fan Motor 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.
LB11660FV Key Features
