Ordering number:EN2575B Monolithic Digital IC LB1641 Bidirectional Motor Driver Overview The LB1641 is a bidirectional motor driver IC. Since it has a 2-input logic circuit and performs the functions of bidirectional driving and braking, it is capable of direct driving 6V, 9V, 12V motors. The output voltage can be varied by using an external zener diode. Package Dimensions unit:mm 3043A-SIP10 [LA1641] Features · 2-input logic can be used to exercise control of bidirectional driving and braking. · On-chip elements to absorb dash current of motor. · Input interfaceable to MOS LSI. · Output voltage variable by use of external zener diode.
