LB1838MEVB: Stepper, 1A/Phase @ 2.5 ~ 9V

The LB1838M is 2-channel low-voltage, low saturation voltage type bidirectional motor driver IC that is optimal for use as 2-phase stepping motor driver 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.

The LB1838M can directly control a motor from signals from a microcontroller. The LB1838M is ideally suited for the stepping motor, two phase excitation, and 1-2 phase excitation drive.

The LB1838M includes a built-in thermal shutdown circuit so that IC scorching or burning is prevented in advance even if the IC outputs are shorted. Additionally, the MFP-14S miniature package used supports reduced-space mounting.
