LB1846MC
Monolithic Digital IC
Low-Voltage/Low Saturation Voltage Type
Bidirectional Motor Driver
Overview
The LB1846MC 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 LB1846MC products can directly control a motor from signals from a microcontroller. The LB1846MC is optimal
for 1-2 phase excitation drive for 2-phase stepping motors using 4-input logic (IN1, IN2, IN3 and IN4).
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 1-2 phase excitation drive for 2-phase stepping motors
• Standby current: Zero
• Low saturation voltage. VO (sat) = 0.55V typical at IO = 400mA
• Thermal shutdown circuit
• No limitations on the magnitude relationship between the power supply voltage (VCC) and the input voltage (VIN)

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
