Equivalent CircuitsThe equivalent circuit diagrams may be simplified or some parts of them may be omitted for explanatorypurposes.2. Test CircuitsComponents in the test circuits are used only to obtain and confirm the device characteristics. Thesecomponents and circuits are not guaranteed to prevent malfunction or failure from occurring in theapplication equipment.IC Usage ConsiderationsNotes on Handling of ICs(1) The absolute maximum ratings of a semiconductor device are a set of ratings that must not beexceeded, even for a moment. Do not exceed any of these ratings.Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may resultinjury by explosion or combustion.(2) Use an appropriate power supply fuse to ensure that a large current does not continuously flow incase of over current and/or IC failure. The IC will fully break down when used under conditions thatexceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormalpulse noise occurs from the wiring or load, causing a large current to continuously flow and thebreakdown can lead smoke or ignition. To minimize the effects of the flow of a large current in case ofbreakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location, arerequired.(3) If your design includes an inductive load such as a motor coil, incorporate a protection circuit into thedesign to prevent device malfunction or breakdown caused by the current resulting from the inrushcurrent at power ON or the negative current resulting from the back electromotive force at power OFF.IC breakdown may cause injury, smoke or ignition.Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable,the protection function may not operate, causing IC breakdown. IC breakdown may cause injury,smoke or ignition.(4) Do not insert devices in the wrong orientation or incorrectly.Make sure that the positive and negative terminals of power supplies are connected properly.Otherwise, the current or power consumption may exceed the absolute maximum rating, andexceeding the rating(s) may cause the device breakdown, damage or deterioration, and may resultinjury by explosion or combustion.In addition, do not use any device that is applied the current with inserting in the wrong orientationor incorrectly even just one time.(5) Carefully select external components (such as inputs and negative feedback capacitors) and loadcomponents (such as speakers), for example, power amp and regulator.If there is a large amount of leakage current such as input or negative feedback condenser, the ICoutput DC voltage will increase. If this output voltage is connected to a speaker with low inputwithstand voltage, overcurrent or IC failure can cause smoke or ignition. (The over current can causesmoke or ignition from the IC itself.) In particular, please pay attention when using a Bridge TiedLoad (BTL) connection type IC that inputs output DC voltage to a speaker directly.Points to Remember on Handling of ICs(1) Heat Radiation DesignIn using an IC with large current flow such as power amp, regulator or driver, please design thedevice so that heat is appropriately radiated, not to exceed the specified junction temperature (Tj) atany time and condition. These ICs generate heat even during normal use. An inadequate IC heatradiation design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown. In addition, please design the device taking into considerate the effect of IC heat radiation withperipheral components.(2) Back-EMFWhen a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back tothe motor’s power supply due to the effect of back-EMF. If the current sink capability of the powersupply is small, the device’s motor power supply and output pins might be exposed to conditionsbeyond absolute maximum ratings. To avoid this problem, take the effect of back-EMF intoconsideration in system design.About solderability, following conditions were confirmed• Solderability(1) Use of Sn-37Pb solder Bath· solder bath temperature = 230°C· dipping time = 5 seconds· the number of times = once· use of R-type flux(2) Use of Sn-3.0Ag-0.5Cu solder Bath· solder bath temperature = 245°C· dipping time = 5 seconds· the number of times = once· use of R-type fluxRESTRICTIONS ON PRODUCT USE060116EBA •The information contained herein is subject to change without notice. 021023_D•TOSHIBA is continually working to improve the quality and reliability of its products.

LD 阳极驱动应用电路 ： ELM186C1A 和 ELM186C2A 用于驱动 LD 阳极。ALD 引脚是 NPN 射极跟随输出引脚。应用 LD 阳极 驱动时，只需要一个电阻用于决定激光输出功率。为防止噪音，建议在VCC 处安装一个噪声吸收电容。工 作电压在红色激光时达到 5V 以上，因要加上 LD 正向电压和 IC 的工作电压。LD 阳极驱动电路在 LD 的 阴极连接到 LDM 外壳时，可连接地线，从而获取良好的散热。此外，还可以减少外部元件数量。为使 APC 环路稳定，在 ELM186C2A 加入相位补偿 CR。

框图的工作说明 : ELM185xB 的 APC 电路利用检测用光电二极管的光电流反馈，控制激光二极管的振荡输出使其成为一 定的稳定值。检测用光电二极管光电流由电阻转换成电压并输入至 AMD 引脚。IC 控制激光二极管电流 , 使 AMD 引脚电压与内部基准电压 0.3V 相等 , 以维持稳定的发光。也就是说，激光的光强度可由连接在 AMD 引脚的电阻值来调整。 激光二极管的驱动电流由连接在 ILM 引脚的电阻转换为电压信号，IC 会限制此电压不让其超过电流 限制电压（0.15Vtyp） ，这样可防止在控制电路发生异常而引起驱动电流过大对激光二极管造成损坏。 为稳定控制反馈环路，连接于 CMP 引脚的相位补偿电容是必要的。在进行快速的 ON/OFF 控制时电 容量可以设定为比较小的值，但至少也要有 3nF 以上的容量值。 激光二极管是由 IC 内部的 NPN三极管开集输出来驱动的。所以，作为激光二极管的驱动电压，可施 加比 IC 的电源电压还要大的电压 （最大为 18V） 。但在驱动电压高的时候， 建议在激光二极管模块 （LDM） 和 KLD 引脚之间加一个电阻，来分散功率的损失。 利用此 IC 的电流检测功能还可以把 AMD 引脚作为 ON/OFF 控制的引脚，可以从外部输入控制信号来 控制激光二极管的闪灭。这时的 ON/OFF 控制的阈值电压为 0.3V。 此 IC 通过在电源和接地之间击穿电压约为 7V 的稳压二极管来吸收浪涌，并通过削减电源线上的浪涌 电压来减少浪涌对激光二极管的损坏。

* 在进行脉冲驱动时，更改应用电路图（1） ，在 AMD 引脚上通过电阻来施加脉冲驱动控制信号； * 如果需要调整检测电流值， 可在上图所示的位置里插入可变电阻（VR1） 。在固定电阻（R1）和可变 电阻（VR1）中间施加脉冲驱动控制信号； * R3: 脉冲驱动控制信号输入电阻的值， 电源电压 VCC 被 R1 和 R3 分压后的电位必须比 Vamd = 0.30Vtyp. 更高。 也就是说必须满足 VCC × R1 ÷ (R3 + R1) ＞ Vamd； 例如） VCC＝3.3V、 R1＝1kΩ时， R3＜R1 × (VCC - Vamd) ÷ Vamd＝1kΩ × (3.3 - 0.3) ÷ 0.3＝10kΩ * 控制信号为 CMOS 等逻辑数字信号。控制信号高时激光光灭，相反低的时候激光光亮。

■应用电路例 2 （脉冲驱动电路）
由外部信号来控制发射激光闪灭的应用电路。如应用电路图（4）所示。 由于激光输出控制电路响应速度的限制，开关的最大频率为 20kHz。利用逻辑门电路可简单地控制 ON/OFF，但与逻辑门电路的输出电阻相比，R1、R2、R3 必须有足够大的电阻值。

激光二极管驱动器
输出为一定并连续驱动激光二极管的电路。激光二极管（LD）大多都是和检测用光电二极管（MD） 一起组合成激光二极管模块（LDM）来使用。 LD 和 MD 的阳极、阴极的 LDM 内部接线类型根据极性、共同引脚的组合方法会有几种不同方式。 下面图（1）～（3）是，使用 ELM185xB 能够简单地连接的 3 种 LDM 的应用电路图∶∶ （电路的参数根据所使用的激光二极管的种类不同其最佳数值会有所变化。表 2 是以在激光二极管的顺 向电流为 35mA、检测二极管的光电流为 0.1μA 时的参数为例。 ）

■应用电路例 3 ( 带有单一故障检测功能的驱动电路 )
根据激光的用途，规格上会要求当单一故障发生时激光的输出仍保证在安全范围内。带有单一故障检 测电路的范例如应用电路图（5）所示。 在使用 ELM185xB 的情况下，全部引脚的单一故障里如发生下面三个原因所造成的短路故障时，会引 起激光输出过大。 １）KLD 引脚发生接地短路故障时（激光二极管电流直接流进接地端，引起激光的光射过大） ； ２）AMD 引脚发生接地短路故障时（会误判激光输出为 0，引起激光的光射过大 )； ３）CMP 引脚和电源电压 VCC 发生短路故障时（电路无法控制，造成激光的光射过大） 。 所以，检测出这 3 种故障的发生，强制停止激光的驱动，就能保证单一故障发生时的电路安全。另外， 电源接通瞬间，电路处于和单一故障发生时相同的状况 ，为了开始时能正常工作，在电路启动时必须 抑制故障的检测（启动电路） 。 应用电路图 5 就是作为这种安全电路的参考例。在异常时由 ELM742B 电压比较器来检测故障，然后 反转由 ELM7SU04BW 构成的锁存器的输出，关闭 ELM33405A 的 PchMOS， 从而切断电源。通过 3 个比 较器检测是否 KLD 引脚在 0.9V 以下、AMD 引脚在 0.1V 以下、CMP 引脚在 2.5V 以上，把比较电路的 输出通过 OR 条件来判断是否异常并切断电源。 启动电路是由电阻 R1、电容 C1 的时间常数来构成的。而基准电压则是根据电阻 R3 ～ R5 和电阻 R8 的分压比率来决定的，但电源电压变化时需要改变电阻值。作为电子元件，电压检测使用 ELM742B， 锁存器可使用 ELM7SU04BW， MOSFET 可使用 ELM33405CA， 当然其他公司的类似产品也同样可以工作。 本电路只是作为参考例来提供的，实际应用于产品时，要充分考虑安全标准来设计电路。 同样在应用电路（2）和（３）上也可以加上检测电路。
