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)
