LB1643

The LB1643 is designed as the forward / reverse motor driver IC. The direction and brake functions are controlled from a single input, and the output voltages can be set by resistors. Further, the output voltage has 3 modes, full, high-level and low-level voltage modes. The output voltage can be controlled from a single input and a microcontroller interface.

Features of the LB1643 are:(1)single-input forward, reverse and brake functions;(2)output voltage can be set using resistors;(3)single-input full-drive, high-level drive and low-level drive select function;(4)microcontroller interface;(5)built-in surge-current absorption;(6)built-in reference voltage circuit;(7)built-in thermal protection circuit.

The absolute maximum ratings of the LB1643 can be summarized as:(1)supply voltage: 18 V;(2)input voltage range: -0.3 to +6 V;(3)output current: +/-1.6 A;(4)power dissipation: 1.2 W;(5)operating temperatrue range: -25 to +75;(6)storage temperature range: -55 to +125.
