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.

Functions

• Optimal for 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

• Through-current prevention circuit

• No limitations on the magnitude relationship between the power supply voltage (VCC) and the input voltage (VIN)

• “Soft off” function that reduces power supply line noise when switching from drive to standby modes. (Requires the use of one external capacitor.)
