All rights reserved. is a registered trademark of Richtek Technology Corporation.Application InformationThe RT5705 is a synchronous low voltage step-down converter that can support the input voltage range from 2.2V to 5.5V and the output current can be up to 1A.Internal compensation are integrated to minimize external component count. Protection features include over current protection, under voltage protection and over temperature protection.UVLO ProtectionTo protect the chip from operating at insufficient supply voltage, the UVLO is needed. When the input voltage of VIN is lower than the UVLO falling threshold voltage, the device will be lockout.EnableThe device can be enabled or disenabled by the EN pin.When the EN pin is higher than the threshold of logic high, the device starts operation with soft-start. Once the EN pin is set at low, the device will be shut down. In shutdown mode, the converter stops switching, internal control circuitry is turned off, and the load is disconnected from the input. This also means that the output voltage can drop below the input voltage during shutdown.Output Voltage SettingThe RT5705 doesn’t require an external resistor divider to program the output voltage. The device by the pins VSEL 1-4. The RT5705 supports an output voltage range of 1.8V to 3.3V in 100mV steps. The output voltage can be changed during operation and supports a simple dynamic output voltage scaling, shown .The output voltage is programmed according to table Table 1.Power GoodWhen the output voltage is higher than PG rising threshold,the PG flag is High.CTRL with Load SwitchThe CTRL pin set to high, the LOAD pin is connected to the VOUT pin via an load switch and can power up an additional, provide sub-system used .If CTRL pin is pulled to GND, the LOAD pin is disconnected from the VOUT pin and internally connected to GND by an internal discharge switch.Inductor SelectionThe recommended power inductor is 2.2μH with over 1.6A saturation current rating. In applications, need to select an inductor with the low DCR to provide good performance and efficiency.C IN and C OUT SelectionThe input capacitance, C IN , is needed to filter the trapezoidal current at the source of the top MOSFET . To prevent large ripple voltage, a low ESR input capacitor sized for the maximum RMS current should be used. RMS current is given by :This formula has a maximum at V IN = 2V OUT , where I RMS =I OUT /2. This simple worst-case condition is commonly used for design because even significant deviations do not offer much relief. Choose a capacitor rated at a higher temperature than required.Several capacitors may also be paralleled to meet size or height requirements in the design.The selection of C OUT is determined by the Effective Series Resistance (ESR) that is required to minimize voltage ripple and load step transients, as well as the amount of bulk capacitance that is necessary to ensure that the control loop is stable. Loop stability can be checked by viewing the load transient response as described in a later section.The output ripple, ΔV OUT, is determined by :⨯OUT RMS OUT(MAX)IN V I = I 1V ⎡⎤∆≤∆⎢⎥⨯⨯⎣⎦OUT L OUT 1V I ESR + 8f C©Copyright 2017 Richtek Technology Corporation.

The maximum allowable power dissipation depends on the thermal resistance of the IC package, the PCB layout, the rate of surrounding airflow,and the difference between the junction and ambient temperatures. The maximum power dissipation can be calculated using the following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction-to-ambient thermal resistance.For continuous operation, the maximum operating junction temperature indicated under Recommended Operating Conditions is 125°C. The junction-to-ambient thermal resistance, θJA , is highly package dependent. For a WDFN-12AL 3x2 package, the thermal resistance, θJA , is 31.5°C/W on a standard JEDEC 51-7 high effective-thermal-conductivity four-layer test board. The maximum power dissipation at T A = 25°C can be calculated as below :P D(MAX) = (125°C − 25°C) / (31.5°C/W) = 3.17W for a WDFN-12AL 3x2 package.The maximum power dissipation depends on the operating ambient temperature for the fixed T J(MAX) and the thermal resistance, θJA . The derating curves in Figure 1 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 1.

描述
IR2175是专为电机驱动设计的单片电流感应IC 。

它通过外接分流电阻测量电机相电流，把模拟信号转换为数字信号，并把该信号输送到低边。

IR 的高压隔离专利技术可以处理高带宽的信号。

输出离散PWM 而不需A/D 输入接口。

过流信号可以使IGBT 短路保护。

漏极开路输出适应3.3V 到15V 电压。

极限额定值
超过极限额定值可能发生错误或者损坏，所有的电压参数是以COM为参考的绝对数值。

所有电流值定义为正值。

热阻和功耗是在空气静止的环境下在电路板上测得的。

推荐操作条件
图一为输出逻辑时序。

设备需工作在推荐操作条件下。

提示：
同时测量PWM周期和PWM有效时间可以消除输出载波频率的温漂。

因为他们是同向波动的。

在每一个周期计算它们的比值可以获得消除温漂的测量值。

IR2175应用指南AN-1052
1 基本功能
本段说明IR2175的基本操作.该IC把高边的电机驱动电流转换到低边。

模拟输入的电压信号实际上是外接感应电阻的压降。

这个电阻感应电机相电流并产生一个很小的交流电压信号。

最大输入信号为260mV。

所以电阻应选择使电压在260mV以内的值，使过流信号电压达到260mV（如10A过流信号选择26mΩ电阻）。

交流输入信号通过IC转换为PWM信号，高边载波频率为130KHz，然后降低PWM电平到低边的参考电平。

PO输出是漏极开路输出，操作电压3.3V到15V。

PO脚需上拉电阻接电源，该上拉电阻典型值为1～10K。

有两种方式处理IR2175的输出信号：
1、用滤波器滤掉载波频率输出模拟信号
2、直接输出数字信号，通过软件算法计算电流
第3、4段会详细说明
Vb和Vs之间的高边浮动电压由自举电路产生，下一段详细说明。

Vbs电压最小8V，推荐Vbs和Vcc电压都在10V以上。

2 自举电路
Vbs电压是建立在Vs电压之上（大部分是高频方波）。

有几种发法可以产生Vbs，一种是自举电路，这个方法简单廉价，但是有一些限制。

占空比和开通时间限制自举电路的充电（长开通时间和高占空比需要充电泵电路，参考AN978）自举电路由二极管和电容组成，见数据手册的模块图。

电路工作方式如下。

当Vs被拉到地，自举电容通过自举二极管从15V Vcc充电。

当Vs被高边拉高时，自举二极管反偏。

略
4 输出信号的数字接口
连接到DSP或者MCU的硬件电路简单得多，大
部分工作都由软件算法来完成。

而且，这种方法不会
带来滤波电路产生的错误信号。

IR2175主要就是为这
种数字应用设计的。

4.1 硬件接口
PO为漏极开路输出，可以从DSP和MCU的3.3V
或者5V电源接上拉电阻。

见右图。

4.2 PWM信号的软件解码
与DSP的典型应用见DT99-8，这是一个TI TM320C240和IR2171/IR2172的硬件电路和软件解决方案
5 Vs引脚瞬态反向的处理
注意：和门极驱动信号不同步，电流感应IC需要自己的瞬态反向保护电路。

和门极驱动信号不同，电流感应IC是持续工作的，必须确保Vs引脚不产生反向。

更多细节可以参考
DT97-3。

注意典型连接里面有一个com 到Vs 的二极管和一个在Vs 和半桥中点之间的电阻，这两个元件使Vs 最多跌落com 一个二极管压降。

这个二极管必须是快速恢复的，最好是小于100ns 的1A 二极管，电阻范围10～20Ohms 。

尽管这个Vs 和半桥中点之间的电阻在电流感应回路中，但是不会影响电流感应信号，因为这个电阻没有电流流过。

只有在transition 发生时，才有持续时间很短的电流。

由于有限的slew rate ，IR2175的输入端放大器会忽略这个短暂的信号。

6 布局建议
功率器件需减少寄生效应。

图九为典型的半桥电路和杂散电感。

每个杂散电感的连线需尽可能宽且短。

IR2175的注意事项和那些门极驱动IC 一样，如图10，退耦电容需尽可能贴近IC 。

V-和Vs 得连线也要尽可能贴近IC 以消除压差。

感应电阻和V+连线尽可能短以减小噪音。

图11给出一个IR2175的布局实例。

注意感测电阻和IC 连接越短越有利于消除电流感应信号的噪音。

大电流走线尽量宽以消除电感。

R2和D2组成的瞬态反向保护电路贴近IC 以产生最大的效果。

注意退耦电容需尽可能贴近IC 的引脚。

7 DV/DT 和对占空比的作用
这也被叫做CMRR （共模抑制比）。

高边是浮动的但是没有开关状态（如Vs 引脚电压固定），将不会产生占空比抖动。

然而在使用两个IC 测量三相电流中的两相这个应用中，Vs 脚在地、近地、直流母线之间转换，每次转换会产生一个dV/dt ，对PO 脚的输出占空比会产生轻微抖动。

直流母线300V 时IR2175的抖动为2%，表一给出不同的母线电压下，IR2171/2和IR2175的dV/dt 。

这个结果是从一个IR 的伺服系统测得的。

电机驱动电路中，这个dV/dt 会转化为转矩波动，因此需要考虑到其影响。
