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
