Ordering number : EN*4944 Monolithic Digital IC LB1668, 1668M, LB1667, 1667M Two-Phase Unipolar Drive Brushless Motor Drivers Preliminary Overview The LB1668 Series 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 p.
• Output protection Zener diodes with variable breakdown voltages — When the Z1 and Z2 pins are open: VOLM = 57 V — When the Z1 and Z2 pins are shorted: VOLM = 32 V — An external Zener diode can be connected between Z1 and VCC.
• Can support both 12-V and 24-V power supplies by changing an external resistor.
• Hall elements can be connected directly.
• 1.5-A output current output transistors built in
• Built-in rotation detection function that outputs low when driven and high when stopped (LB1668/M)
• FG signal function that sets FG high when IN- is low, and sets FG low when IN- is high (LB166.
