LB1943
Forward/Reverse Motor Driver with Braking Function
Overview
The LB1943 is a forward/reverse motor driver IC. This IC
supports forward, reverse, and braking control from a
single input, and the desired output voltage can be set with
a resistor. Either full drive or VC drive can be selected
from the single input, and the LB1943 can be controlled
from a microprocessor.
Functions
• Single-input control of forward, reverse, and braking
operations
• Resistor output voltage setup
• Either full drive or VC drive can be selected from the
single control input.
• Can be controlled from a microprocessor.
• Built-in motor dash current absorbing device
• Built-in reference voltage circuit
• Built-in thermal protection circuit

6. During motor drive, large currents (on the order of several hundred mA) flow in the motor power supply block.
Therefore, the printed circuit board layout and interconnections must be designed so that there are no shared devices.
7. If negative voltages are applied to OUT1 and OUT2 and the IC operates incorrectly, insert Schottky diodes between
OUT1 and ground and between OUT2 and ground.
