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
