主流步进驱动IC选型指南

主流步进驱动IC选型指南特点点评：1. TB6600作为东芝最新的大功率驱动IC，拥有最大50V@5A驱动能力，最高16细分，适用于部分86及全系列57步进电机，芯片自带欠压、过流、短路保护，而且自带5V逻辑电源，和LV8727并列为目前最高性价比的大功率驱动IC。

2. TB6560AHQ无疑是目前应用最多最广泛的步进驱动IC，适用于57及以下步进电机，由于出货量大所以价格便宜，且现货充足。

3. TB62209是最成熟的表贴式步进驱动IC之一，也曾经是性价比最高的42系列步进驱动芯片，但正逐渐被LV8731所取代。

4. LV8726是三洋针对于大中华区特别设计的一款驱动IC，电压高达60V，因为是外接Mosfet所以电流可以达到10A，最大128细分，且具有目前所有主流驱动IC的功能，目前还在内部测试中，预计今年下半年可以面市。

5. LV8727是三洋已经批量供货的最大功率驱动IC，前身是三洋给国内某公司定制的THB8128，三洋被安森美收购后将此IC做了工艺升级并小幅改善了封装方式，拥有最大********驱动能力，虽然稍逊于东芝的TB6600，但此IC细分数高达128，除了常用的保护功能外，还带有自动半流功能，价格也与TB6600相当，因此和TB6600并列为最高性价比大功率驱动IC。

6. LV8729是目前性价比最高的高细分表贴驱动IC，前身是三洋给国内某公司定制的THB6128，三洋被安森美收购后同样将此IC做了工艺升级，且大幅改善了封装和管脚排列方式，适用于部分57、全系列42及以下电机。

7. LV8731是三洋推出的非常成功的一款马达驱动IC，被誉为同级别中最高性价比，原本三洋的策略是剑指东芝的TB62209，但经过测试我们发现参数和驱动能力完全超越后者，已经和Allegro最成熟的A3977同一水准，且凭借新的工艺、多重保护以及自带逻辑5V，使得A3977也只能望尘莫及。

因此在2A以内电流的应用中，如果没有高细分的要求，LV8731是最好的选择。

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。

The Duty Cycle of the resulting PWM signal is thus directly, linearly controlled by VSP pin voltage: from the Min of VSAWL to the Max of VSAWH. That is, when VSP is below VSAWL, the PWM duty cycle is at the Minimum value of 0%. when VSP is above VSAWH, the PWM duty is at the Maximum value of 100%. The ECN30206 operates in 2 quadrants by chopping the BOTTOM Arms with this PWM duty cycle during the appropriate commutation times (phases). Thus, the duty cycle controls motor torque and speed.3.4 Over Current Limit OperationOver-Current is monitored via the voltage drop across an external resistance RS. If the input voltage at the RS pin exceeds the internal Reference voltage (Vref is typically 0.5V), all BOTTOM Arms are Turned-OFF. Following an Over Current event, reset is automatically attempted during each period of the on-chip OSC. This on-chip OSC signal is available at the VTR pin.3.5 Motor Rotation Direction Output FunctionThe rotation direction of the motor is outputted as a logic signal at the DM pin. The table below shows the DM output signals for the two (2) possible rotation directions.Rotation Direction DM OutputU→V→W LowU→W→V High3.6 VCC Under-Voltage DetectionIf VCC drops below LVSDON (12.0V typ), all IGBTs (TOP and BOTTOM Arms) Turn-OFF. Normal operation returns when VCC rises above LVSDOFF: the value of LVSDOFF is LVSDON + Vrh.3.7 All Output IGBT Shut-OFF FunctionWhen VSP drops below Voff (1.23V typ), all IGBTs (TOP and BOTTOM Arms) Shut-OFF.VSP Input Voltage TOP Arm Outputs BOTTOM Arm Outputs0V ≤ VSP < Voff All IGBTs are OFF All IGBTs are OFFVoff ≤ VSP < VSAWL Following the 3.1 Truth Table All IGBTs are OFF VSP ≥ VSAWL Following the 3.1 Truth Table Following the 3.1 Truth TableWhen a motor is rotating and VSP drops below Voff, the VS voltage can rise.Also in this condition VS must not exceed the 500VDC Breakdown Voltage.4.

理论最大速度可按照电机额定的最大转速计算。

通常步进电机的最大转速范围在100-5000RPM之间。

可用速度范围受到供电电压、电机驱动方式、驱动电流等因素的影响。

BLDC与主控芯片,先进控制带来高效优势

BLDC与主控芯片，先进控制带来高效优势目录1.前言 (1)2.高效BLDC的复杂控制 (1)3.低成本高性价比方波控制 (2)4.高成本高效率FOC先进控制 (2)5.小结 (4)1.前言从简单的电动工具、电风扇到复杂的机器人、汽车电机，许多机器设备都使用高能效的无刷直流电机BLDe将电能转换为旋转运动。

在高效率、高扭矩、低噪音、长寿命、响应快速等优势的加持下，越来越多电动设备开始向BLDC转变。

虽然BLDC有着这么多优势，但实现BLDC的控制是相对较难的，比有刷电机难很多而且硬件成本也更高。

2.高效BLDC的复杂控制从工作原理上来看，BLDC作为电机，其基本构造也是定子加转子，不过其定子和转子和有刷电机是相反的。

BLDe的定子是通电的线圈，转子是永磁体。

那么根据电磁感应原理，只要给定子上的线圈接入适当方向的电流，让产生的磁极方向与永磁体的磁极相对应，就可以旋转起来。

也就是说，控制电流的大小和方向，就能控制转子的旋转。

进一步对接入电流线圈的定子进行优化，就能产生很多控制方式。

BLDC的控制虽然在原理上和有刷电机相似，但实现起来却要难得多，BLDe需要复杂的控制器才能将单个直流电源转换为三相电压，而有刷电机可以直接通过调节直流电压来控制。

原理层面固然通俗易懂，但是真正实现起来，控制BLDC的难度还是不小的。

控制电流的大小和方向就能控制转子的旋转，这里有很多控制算法的应用。

然后还需要知道转子的位置，对位置的测量是确定电机何时换相所需的输入。

对于转子位置的感测，又区分出有传感器和无传感器的路线。

对开环控制而言，这些已经足够，但是在需要精确速度控制的场景里，加入PID闭环的控制是有必要的。

对于闭环速度控制，需要对转子速度或电机电流以及PWM 信号进行测量，以控制电机速度以及功率。

目前的BLDC配置，硬件层面绝大多数控制方式都以六个功率开关器件构成的电子换相电路搭配成全桥，控制和驱动组合，再加上位置反馈电路和电流采样电路。
