LB1668 Datasheet | SANYO

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 ponents. They also support the formation of motor lock protection and automatic recovery circuits. Package Dimensions unit: mm 3098B-DIP10S [LB1668, 1667] Functions and Features - 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 (LB1667/M) - Motor lock protection and automatic recovery functions built in - Thermal shutdown function SANYO: DIP10S unit: mm 3111-MFP14S [LB1668M, 1667M] SANYO: MFP14S Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum input current Output voltage Output current Output minus current RD/FG influx current RD/FG voltage Symbol ICC max VOUT IOUT IOM IRD/IFG VRD/VFG Pd max t ≤ 20 ms - : These specifications are subject to change for improvement without notice.
