•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
• Built-in thermal protection
• FG output
• Direct Hall element connection possible
