【应用】GaN驱动器SGM48017助力激光雷达设计,传播延迟低于30ns,灌电流输出高达7.6A
随着工业的快速发展,人类迎来智能化、自动化时代,例如激光雷达的应用它是一种对目标物件照射激光脉冲来测量物件的距离的方法。
图1 激光雷达工作原理示意图
如上图1所示,其工作原理是通过GaN的高频开关来激发激光二极管,Gan器件具有更高的脉冲幅度,可以实现更远的距离,较窄的脉冲宽度相当于具有更高分辨率,在激光雷达的应用上硅基GaN FET相比MOSFET的性能有了大幅提高,使得激光雷达的性能变得更为容易实现,针对GAN器件的驱动需要选择一款传输延迟比较低的器件,才能满足GAN高频窄脉冲的应用。
本文重点介绍国产圣邦微(SGMICRO)的GaN驱动器SGM48017助力激光雷达发射链路中GaN的驱动设计,SGM48017是一款高速功率MOSFET/GaN栅极驱动器,具有保护功能,如过电压、热关机保护(TSD)、欠电压闭锁和短路保护。超小型SOT-23-5封装,较宽的工作温度范围-40℃到+125℃。
图2 激光雷达功率发射链路框图
如上图2所示,SGM48017用于充电回路的MOS驱动,另外就是放电回路的GAN驱动,两个驱动复用一颗,减少BOM的多个型号,且能降低BOM成本,对于GaN器件栅极驱动器选型,需要注意驱动芯片的驱动电流能力,ns级的传播延迟,高达MHZ的开关频率,带有欠压、过热保护、电路设计简单;GaN的Vgs电压比较窄,一般是在±6V,设计驱动电压是要留有足够的余量,避免栅栅极出现过压的情况;栅极驱动器的设计应尽量减小VDD电源电容与漏极和源极器件之间的栅极功率环路电感。这将栅极驱动器的上升时间减至最少,并使得驱动器的di/dt可以最大化。
图3 SGM48017封装以及引脚定义图
综上所述,国产SGMICRO的GaN驱动器SGM48017助力激光雷达设计具有以下几点优势:
1、驱动电流大,6.4A的拉电流和7.6A灌电流输出能力,保证GaN FET可靠开通和关断;
2、低于30ns的传播延迟与最小的容差和变化,允许在高频率下高效运行,满足高频应用;
3、具有更多的保护功能,如过电压、热关机保护(TSD)、欠电压闭锁和短路保护等,提高系统可靠性;
4、超小的SOT-23-5封装,可最大限度地降低栅极回路电感,并最大限度提升高频功率密度要求。
