Description Two-Phase Unipolar Driver
Datasheet LB1965M DatasheetLB1965M Datasheet (PDF)

Ordering number : ENN6189 LB1965M Monolithic Digital IC LB1965M Two-Phase Unipolar Driver for Variable-Speed Fan Motor Features • With only a few peripheral parts including a thermistor, ambient temperature dependent continuous speed control can be implemented. This allows low-speed startup (100% duty drive at startup). • Settable minimum rotation speed for low temperature • Built-in thermistor voltage amplification circuit assures high precision of ambient temperature to rotation speed ratio .
