3023A-SIP14H
[LB1646]
Overview
The LB1646 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 and the output current can be limited at the
time of overload.
Features
2-input logic can be used to exercise control of bidirec-
tional driving and braking.
Input connectable direct to MOS LSI.
Output voltage variable by use of external Zener diode.
On-chip output current limiter.
On-chip minimum output voltage control circuit.
Variable output current limit slope.
On-chip circuit to turn ON/OFF the output current
limit function.
