LB1846 Datasheet (Sanyo) - Low-Voltage/Low Saturation Voltage Type Bidirectional Motor Driver

LB1846, Low-Voltage/Low Saturation Voltage Type Bidirectional Motor Driver

Ordering number : 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 transistors in the upper side and npn transistors in the lowe
