• 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)
