Ordering number : ENA2036A  
Monolithic Digital IC  
Low-Voltage/Low Saturation Voltage Type  
Bidirectional Motor Driver  
LB1848MC  
Overview  
The LB1848MC is 2-channel low-voltage, low saturation voltage type bidirectional motor driver IC that is 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, and they achieve low  
saturation output and low power characteristics despite being provided in a miniature package.  
The LB1848MC products can directly control a motor from signals from a microcontroller. The LB1848MC 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 IC include built-in thermal shutdown circuits so that IC scorching or burning is prevented in  
advance even if the IC output is shorted.  
Functions  
• Optimal for 2-phase excitation drive for 2-phase stepping motors  
• Standby current: Zero  
• Low saturation voltage. V (sat) = 0.55V typical at I = 400mA  
• Thermal shutdown circuit  
O
O
• Through-current prevention circuit  
• No limitations on the magnitude relationship between the power supply voltage (V ) and the input voltage (V  
)
CC IN  
• “Soft off” function that reduces power supply line noise when switching from drive to standby modes. (Requires the  
use of one external capacitor.)
