LB1846 Description
EN5339 Monolithic Digital IC LB1846M, 1848M Low-Voltage/Low Saturation Voltage Type Bidirectional Motor Driver Overview The LB1846M and LB1848M are 2-channel low-voltage, low saturation voltage type bidirectional motor driver ICs that are optimal for use as 2-phase stepping motor drivers in printers, floppy disk drives, and cameras and other portable equipment. The output circuits are of the bipolar type, with pnp...
