LB1943

Ordering number : EN5806 Monolithic Digital IC 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. Package Dimensions unit: mm 3043A-SIP10 [LB1943] 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.
