Product Description
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, 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, achieving low saturation output and low power characteristics despite being provided in a miniture package.
Both of these IC products can directly control a motor using 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).
These circuits also 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 miniture package used supports reduced-space mounting.
