LB1668M - 2-phase Unipolar Brushless Motor Driver

Download the LB1668M datasheet PDF. This datasheet also covers the LB1668 variant, as both devices belong to the same 2-phase unipolar brushless motor driver family and are provided as variant models within a single manufacturer datasheet.

Features

  • a wide usable voltage range and a minimal number of required external components. It also supports 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 = 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 Ch.
