LB1848MGEVB: Bidirectional Motor Driver IC Evaluation Board

The LB1848M/LB1848MC 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 LB1848M can directly control a motor from signals from a microcontroller. The LB1848M is optimal for 2-phase excitation drive for 2-phase stepping motors using 3-input logic (ENA, IN1, and IN2).The LB1848M 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-10S miniature package used supports reduced-space mounting.
