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 lower side, and they achieve low

saturation output and low power characteristics despite

being provided in a miniature package.

Both of these IC products can directly control a motor

from signals from a microcontroller. The LB1846M is

optimal for 1-2 phase excitation drive for 2-phase stepping

motors using 4-input logic (IN1, IN2, IN3, and IN4) and

the LB1848M is optimal for 2-phase excitation drive for

2-phase stepping motors using 3-input logic (ENA, IN1,

and IN2).

Another point is that these ICs include built-in thermal

shutdown circuits so that IC scorching or burning is

prevented in advance even if the IC outputs are shorted.

Additionally, the MFP-10S miniature package used

supports reduced-space mounting.
