LB1668
LB1668M
Monolithic Digital IC
2-Phase Unipolar
Brushless Motor Drivers
http://onsemi.com
Overview
The LB1668 and LB1668M are 2-phase unipolar drive brushless motor drivers that feature a wide usable voltage range
and a minimal number of required external components. They also support the formation of motor lock protection and
automatic recovery circuits.
Features
• Output protection Zener diodes with variable breakdown voltages
When the Z1 and Z2 pins are open : VOLM = 57V
When the Z1 and Z2 pins are shorted : VOLM = 32V
An external Zener diode can be connected between Z1 and VCC.
• Can support both 12V and 24V power supplies by changing an external resistor.
• Hall elements can be connected directly.
• 1.5A output current output transistors built in.
• Built-in rotation detection function that outputs low when driven and high when stopped.
• Motor lock protection and automatic recovery functions built in.
• Thermal shutdown function.
