These are forstress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability.Note 2. θJA is measured in natural convection at T A = 25°C on a high effective thermal conductivity four-layer test board ofJEDEC 51-7 thermal measurement standard. The measurement case position of θJC is on the exposed pad of the package.Note 3. Devices are ESD sensitive. Handling precaution is recommended.Note 4. The device is not guaranteed to function outside its operating conditions.Note 5. Quiescent, or ground current, is the difference between input and output currents. It is defined by I Q = I IN - I OUT under noload condition (I OUT = 0mA). The total current drawn from the supply is the sum of the load current plus the ground pin current.Note 6. Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown signal (V EN>1.8V ).Note 7. The dropout voltage is defined as V IN − V OUT , which is measured when V OUT is V OUT(NORMAL) −Σ 100mV.Note 8. Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices are tested for loadregulation in the load range from 10mA to 1.0A.Note 9.

介绍几种机器人驱动芯片
介绍几种机器人驱动芯片作者：机器人发烧友MONDAY, 08 SEPTEMBER 2003 05:28在自制机器人的时候，选择一个合适的驱动电路也是非常重要的，本文详细介绍了几种常用的机器人驱动芯片。
介绍几种机器人驱动芯片(注：本文已经投稿至《电子制作》)在自制机器人的时候，选择一个合适的驱动电路也是非常重要的。
最初，通常选用的驱动电路是由晶体管控制继电器来改变电机的转向和进退，这种方法目前仍然适用于大功率电机的驱动，但是对于中小功率的电机则极不经济，因为每个继电器要消耗20~100mA的电力。
当然，我们也可以使用组合三极管的方法，但是这种方法制作起来比较麻烦，电路比较复杂，因此，我在此向大家推荐的是采用集成电路的驱动方法：马达专用控制芯片LG9110芯片特点：低静态工作电流；✍✍宽电源电压范围：2.5V-12V ；✍✍每通道具有800mA 连续电流输出能力；✍✍较低的饱和压降；✍✍TTL/CMOS 输出电平兼容，可直接连CPU ；✍✍输出内置钳位二极管，适用于感性负载；✍✍控制和驱动集成于单片IC 之中；✍✍具备管脚高压保护功能；✍✍工作温度：0 ℃-80 ℃。
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路器件，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。
管脚定义：1 A 路输出管脚、2和3 电源电压、4 B 路输出管脚、5和8 地线、6 A 路输入管脚、7 B 路输入管脚2、恒压恒流桥式1A驱动芯片L293图2是其内部逻辑框图图3是其与51单片机连接的电路原理图L293是著名的SGS公司的产品，内部包含4通道逻辑驱动电路。

Refer to P10-12 for simulation detail.(Note 2) Pin information for BD9G401EFJ_AVE is same like Table 2.Caution◼These model characteristics are specifically at Ta = 25 °C. Thus, the simulation result with temperature variances may significantly differ from the result with the one done at actual application board (actual measurement).◼The simulation result and characteristics described in this report may differ depending on the board design.It is recommended to perform the measurement on the actual board to verify the result.◼The values from the simulation results are not guaranteed. Use these results as a guide for your design.◼Actual measurement was done using a specific sample, thus the measured data is just as a reference.BD9G401EFJ Spice Model◼ Pin InformationFigure 1 Symbol of BD9G401EFJ◼ Model ParameterTable 3 Model Parameter TableU1BD9G401EFJFSW = 300kSOFTSTARTRATIO = 1.0FB 4VCC8VC 3GND 2EN6SYNC5BST7LX 1(Note 1) These parameters for SPICE models only. it cannot be set on the device.If the parameters are changed, the behavior will be different from the actual device.Verifiable Characteristics◼Electrical Characteristics (vs. Datasheet) (4)◼Characteristic in SPICE (vs. Measured Waveform) (5)➢BD9G401EFJ✓Output Ripple Voltage (VIN = 12 V, VOUT = 5 V) (5)✓Switching Frequency (VIN = 12 V, VOUT = 5 V) (6)✓Load Regulation (VIN = 12 V, VOUT = 5 V) (7)✓Load Response (VIN = 12 V, VOUT = 5 V, IOUT = 0.875 A to 2.625 A) (8)✓Load Response (VIN = 12 V, VOUT = 5 V, IOUT = 2.625 A to 0.875 A) (9)➢BD9G401EFJ_AVE✓Frequency Characteristic (VIN = 12 V, VOUT = 5 V, IOUT = 3.5 A) (10)✓Frequency Characteristic (VIN = 36 V, VOUT = 24 V, IOUT = 3.5 A) (11)Electrical Characteristics (vs. Datasheet)Table 4 Electrical Characteristics Comparison(Note 1)Yes: Model available (supported), No: Model not available” (not supported).1.VOUTTimev(vout)+0.015Figure 2.Simulation Schematic 1Figure 3.Output Ripple Voltage (VIN = 12 V, VOUT = 5 V)(Measured Waveform)Figure 4.Output Ripple Voltage (VIN = 12 V, VOUT = 5 V)(SPICE Simulation)Time = 2 μs /divV OUT : 10 mV/divTime = 2 μs/divTable 5 Characteristics Comparison(Note 1) The above data is based on a specific sample and it is not a guaranteed value.(Note 2) These characteristics depend on some dynamic characteristics of external components, input signal speed,2.LXDRBR5LAM60ATFTimev(lx)Figure 5.Simulation Schematic 2Figure 6.Switching Frequency (VIN = 12 V, VOUT = 5 V)(Measured Waveform)Figure 7.Switching Frequency (VIN = 12 V, VOUT = 5 V)(SPICE Simulation)Table 6 Characteristics ComparisonLX : 5 V/divTime = 2 μs/div(Note 1) The above data is based on a specific sample and it is not a guaranteed value.(Note 2) These characteristics depend on some dynamic characteristics of external components, input signal speed,3.
