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
• 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
