Product Summary
The LB1668 is a 2-phase unipolar drive brushless motor driver that features a wide usable voltage range and a minimal number of required external components. The LB1668 also supports the formation of motor lock protection and automatic recovery circuits.
Parametrics
LB1668 absolute maximum ratings: (1)Maximum input current, ICC max: 200 mA when t ≤ 20 ms; (2)Output current, IOUT: 1.5 A; (3)Output minus current, IOM: –50 mA; (4)RD/FG influx current, IRD/IFG: 10 mA; (5)RD/FG voltage, VRD/VFG: 30 V; (6)Allowable power dissipation, Pd max: 1.1 W; (7)Operating temperature, Topr: –30 to +80℃; (8)Storage temperature, Tstg: –55 to +150℃.
Features
LB1668 features: (1)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; (2)Can support both 12-V and 24-V power supplies by changing an external resistor; (3)Hall elements can be connected directly; (4)1.5-A output current output transistors built in; (5)Built-in rotation detection function that outputs low when driven and high when stopped (LB1668/M); (6)FG signal function that sets FG high when IN- is low, and sets FG low when IN- is high (LB1667/M); (7)Motor lock protection and automatic recovery functions built in; (8)Thermal shutdown function.
