LB1846MC-AH

The LB1846MC-AH is a 2-channel low-voltage/low saturation voltage type bidirectional Motor Driver IC optimal for use as 2-phase stepping motor drivers in printers and cameras. The output circuits are of the bipolar type, with PNP transistors in the upper side and NPN transistors in the lower side and it achieve low saturation output and low power characteristics despite being provided. It can directly control a motor from signals from a microcontroller. It is optimal for 1 to 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.

• Low voltage and wide operation
• Thermal shutdown circuit
• Reduction of substrate size
• Standby current - Zero
• Low saturation voltage -VO (sat)=0.55V typical at IO=400mA
• 800mA/channel Ground pin-outflow current
• 870mW Allowable power dissipation
