介绍几种电机驱动芯片［作者：佚名转贴自：本站原创点击数：1493 更新时间：2005-4-22 文章录入：白桦］减小字体增大字体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。

L298N 电机驱动板L298N是意法半导体（STSemiconductor）集团旗下量产的一种双路全桥式电机驱动芯片，拥有工作电压高、输出电流大、驱动能力强、发热量低、抗干扰能力强等特点，通常用来驱动继电器、螺线管、电磁阀、直流电机以及步进电机。

什么是L298N？L298是L293电机驱动芯片的高功率、大电流版本，由Multiwatt 15封装，N是L298的封装标识符，另外还有其他两种不同类型的封装方式：L298N就是L298的立式封装，源自意法半导体集团旗下品牌产品，是一款可接受高电压、大电流双路全桥式电机驱动芯片，工作电压可达46V，输出电流最高可至4A，采用Multiwatt 15脚封装，接受标准TTL逻辑电平信号，具有两个使能控制端，在不受输入信号影响的情况下通过板载跳帽插拔的方式，动态调整电路运作方式，有一个逻辑电源输入端，通过内置的稳压芯片78MO5，使内部逻辑电路部分在低电压下工作，也可以对外输出逻辑电压5V，为了避免稳压芯片损坏，当使用大于12V驱动电压时，务必使用外置的5V接口独立供电。

L298N通过控制主控芯片上的I/O输入端，直接通过电源来调节输出电压，即可实现电机的正转、反转、停止，由于电路简单，使用方便，通常情况下L298N可直接驱动继电器（四路）、螺线管、电磁阀、直流电机（两台）以及步进电机（一台两相或四相）。

This is information on a product in full production.June 2018DocID13405 Rev 61/32STP08DP05Low voltage 8-bit constant current LED sink with full outputs errordetectionDatasheet - production dataFeatures∙Low voltage power supply down to 3 V ∙8 constant current output channels ∙Adjustable output current through external resistor ∙Short and open output error detection ∙Serial data IN/parallel data OUT ∙ 3.3 V micro driver-able ∙Output current: 5-100 mA ∙30 MHz clock frequency∙Available in high thermal efficiency TSSOP exposed pad ∙ESD protection 2.5 kV HBM, 200 V MMDescriptionThe STP08DP05 is a monolithic, low voltage, low current power 8-bit shift register designed for LED panel displays. The STP08DP05 contains a 8-bitserial-in, parallel-out shift register that feeds a 8-bitD-type storage register. In the output stage, eight regulated current sources were designed to provide 5-100 mA constant current to drive the LEDs.The STP08DP05 is backward compatible in the functionality and footprint with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks 3 different conditions that can occur on the output line: short to GND, short to V O or open line. The data detection results are loaded in the shift register and shifted out via the serial line output.The detection functionality is implemented without increasing the pin number, through a secondary function of the output enable and latch pin (DM1 and DM2 respectively), a dedicated logicsequence allows the device to enter or leave from detection mode. Through an external resistor, users can adjust the STP08DP05 output current, controlling in this way the light intensity of LEDs, in addition, user can adjust LED’s brightness intensity from 0% to 100% via OE/DM2 pin.The STP08DP05 guarantees a 20 V outputdriving capability, allowing users to connect more LEDs in series. The high clock frequency,30MHz, also satisfies the system requirement of high volume data transmission. The 3.3 V of voltage supply is well useful for applications that interface any micro from 3.3 V. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor.Table 1.
