电路中,晶体管常常被用来当做开关使用。晶体管用作开关时有两种不同的接线方式:高边(high side)和低边(low side)。高边和低边是由晶体管在电路中的位置决定的。晶体管可以是双极性晶体管(BJT)或者场效应管(MOSFET)。 1. 低边晶体管电路 低边开关,晶体管接地,也就是说晶体管在负载和地之间。由于晶体管正在...
英飞凌的智能功率开关产品在行业内处于领先地位,无论从产品性能还是从设计的集成度来说,相对友商都是有很大的优势。 决定High Side Switch好坏的参数有很多,相对来说,这部分内容会更复杂一些,你可以参考这篇AN详细了解。 当然相关的技术文档还有很多,随着你的学习不断深入,可以经常...
High-Side MOSFET的意思是：桥式电路中上桥MOS管全桥推挽电路中，有四个mos管，左端和右端，左端有上面的是高端high side，下面的是low side。low side 一般指MOSFET接地，其驱动信号是基于地信号的，在驱动电路中不需要加电压抬升电路，如果是high side即常说的高端驱动，其驱动信号是浮动的，需要电压...
Figure 1. Simplified logic output stage showing the high-side and low-side switches. Most micro-controllers and logic families have output stages which can connect the output to the positive supply or to ground. This allows the micro to put a definite ‘high’ (+5 V in this example) onto...
HIGH-SIDE SWITCH AND LOW-SIDE SWITCH LOSS EQUALIZATION IN A MULTIPHASE SWITCHING CONVERTERAn electrical system includes a motor and a plurality of switch pairs, each switch pair having a high-side switch, a low-side switch, and a switch node coupled to the motor. The electrical system also ...
However, step back and think about what the two different circuit types are doing. The low-side switch is switching ground while the high-side switch is connecting the voltage supply. Generally, you want to keep the ground connected in a circuit and switch the power. One reason is that eve...
Understand low-side vs. high-side current sensing.The article focuses on the resistive-sensing techniques available in the semiconductor industry. It notes that the technique will provide accurate and cost-effective measurements of DC current for various applications. Moreover, it also explains the ...
high side和..lowside的意思就是轮子失去抓地力,滑出去了。只要有缓冲区一般不会伤到车手,比如倾角过大,或者有水,或者刹车抱死h噻就不一样了,h噻一般只有一个原因,那就是在弯道油门开早,车身未正的时候,后轮的力
