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 • Built-in motor lockup protection and automatic recovery circuit Output current Io = 1.
5A, built-in output stage protection Zener diode – Low-noise protection with chip capacitors also possible • Bu...
