【应用】力特FET驱动器IX4340助力服务机器人激光雷达驱动,低传播延迟,峰值电流高达5A
激光雷达多应用在空间测绘领域,随着AI行业的兴起,激光雷达已成为汽车以及机器人上不可或缺的“眼睛”,可进行实时定位导航,实现自主判断。常见的激光雷达的原理基本都是通过对被测物体发射激光光束,并接收该激光光束的反射波,记录该时间差,从而确定被测物体与测试点的距离。
笔者曾接触过几个激光雷达的项目,都是应用在商用服务机器人机器人上的激光测距雷达。已知激光管的功率普遍较高,需要通过高速驱动芯片驱动GaN管的来控制激光管的通断,达到发射激光的目的,如图1所示
图1 激光管驱动原理
MOS管接收到来自驱动芯片的信号快速响应,打开通道,点亮激光管;由于在实际测距中,MOS管、激光管等器件都是工作在高速的状态,配合接收头高速响应得到测量值;因此,MOS驱动芯片的配合起到了尤为关键的作用。
LITTELFUSE(力特)公司是电路保护领域的全球领先企业,提供种类最多、范围最广的电路保护产品组合,向业界提供最广泛且最尖端的电路保护产品及解决方案产品组合。本文将重点介绍力特的FET驱动器IX4340用于服务机器人激光雷达驱动。
IX4340是一款双、大电流、低压侧栅极驱动器。两个输出中的每一个都能够产生和降低5A的峰值电流,这两个输出可以并联用于更高电流的应用,满足常见小功率激光管的驱动;最大额定电压为20V,适应大部分电压环境;快速传播延迟时间(通常为16ns)和快速上升和下降时间(7ns)使IX4340非常适合高频应用,满足在激光雷达上高速的要求。
图2 IX4340内部原理图
力特的IX4340原理结构简单,结合小体积SOP-8和MSOP-8封装特点,大大节省Layout的体积。
最后,总结力特的IX4340在激光测距雷达上的优势:
1.单通道大电流,高达5A的峰值电流,可以并联用于更高电流的应用;
2.低传播延迟(典型值低于16ns)快速上升和下降时间(7ns),满足激光TOF雷达高频设计的需求;
3.最大额定电压为20V,适应大部分电压环境;
4.紧凑的SOP-8和MSOP-8封装,超小体积,节省电路设计空间。

【方案】PCR仪精准高效温控系统优选元器件方案
描述- PCR仪一般温度循环为25-90-50-72℃、循环25次以上,早期的PCR仪采用水浴、风扇或压缩机制冷,控温精度较低且调温时间长,导致其无法满足市场上对PCR仪精准、高效的要求。本方案采用II-VI MARLOW公司的高可靠性半导体制冷片、Laird公司的高导热率导热垫片等相关器件,利用半导体制冷片快速温度响应的特点,不仅实现了PCR仪精准、高效的温度控制,而且具有小体积、高可靠性的特点。
