... LB11660FV 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 • Single-phase full-wave drive (15V, 1.5A transistors are built in) Half predriver with integrated high side transistor • ...

... Since the current limiter circuit applies limitation at a current determined VRf/Rf (where VRf = 0.5V (typical), Rf: resistance of the current detection resistor), the current limiter will operate when Rf = 0.5Ω. The resistor RF must be connected in the circuit and it must have a value such that the circuit operates within the recommended current limiter operating range. LB11660FV * 4.7μ ...
