Overview

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, floppy disk drives, and cameras and other

portable equipment.

Features

• Optimal for 1-2 phase excitation drive for 2-phase stepping motors (LB1846M)

• Optimal for 2 phase excitation drive for 2-phase stepping motors (LB1848M)

• Low saturation voltage. VO(sat) = 0.55 V typical at IO=400 mA

• Standby current: zero

• Thermal shutdown circuit

• Miniature package: MFP-10S (6.5 ×5.1 mm)

• Through-current prevention circuit (LB1848M only)

• “Soft off” function that reduces power supply line noise when switching from drive to standby modes. (Requires the use of one external capacitor.) (LB1848M only)

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

(VIN)
