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

• Built-in thermal protection

• FG output

• Direct Hall element connection possible
