描述：
LG9110是为控制和驱动电机设计的两通道推挽式功率放大专用集成电器器件，将分立电路集成在单片IC
之中，使外围器件成本降低，整机可靠性提高。该芯片有两个TTL/CMOS兼容电平的输入，具有良好的抗干扰
性；两个输出端能直接驱动电机的正反向运动，它具有较大的电流驱动能力，每通道能通过750-800mA的持
续电流，峰值电流能力可达1.5-2.0A；同时它具有较低的输出饱和压降；内置的钳位二极管能释放感性负载
的反向冲击电流，使它在驱动继电器、直流电机、步进电机或开关功率管的使用上安全可靠。LG9110被广泛
应用于玩具汽车电机驱动、步进电机驱动和开关功率管等电路上。

1st, low quiescent operation electric current;
2nd, wide supply voltage scope: 2.5V-12V;
3rd, each channel has the 800mA uninterrupted current output capacity;
4th, low saturated pressure drop;
5th, the TTL/CMOS power output is compatible, may link CPU directly;
6th, control and actuation integration in monolithic IC;
7th, has the base pin high pressure protection function;
8th, operating temperature: 0℃-80℃.
LG9110 is to control and actuate the electric machine design two channel push-pull type power amplification special-purpose integration electric appliance component, the discrete circuit integration in monolithic IC, will cause periphery component cost reduction, the complete machine reliability enhancement. This chip has two TTL/CMOS compatible level input, has the good anti-jamming; Two out-ports can the direct drive electrical machinery's forward and reverse movement, it have the big electric current driving force, each channel can through the 750-800mA sustained current, summit current ability be possible to reach 1.5-2.0A; Simultaneously it has the low output saturated pressure drop; The built-in clamp diode can release the perceptual load the reverse surge current, causes it, in actuates the relay, the direct current machine, to step-by-step the electrical machinery or in the switch power tube's use safe reliable. LG9110 is widely applied in the toy car motor-driven, step-by-steps electric circuits and so in motor-driven and switch power tube.
