如图2.2,是典型的高位MOSFET开关电路,一般MOSFET的GS间耐压是20V,最大的输入电压是24V,所以MOSFET的GS有过压损坏的风险,因此此处使用了一颗18V稳压管对Vgs进行了钳位防护。 图2.2,High-Side Switch中GS极的防护 (四)、MOSFET的开关电路的奇怪现象——漏电 如图2.2的MOSFET开关电路,有时候会出现奇怪的现象,即使开关未...
IPD 的全称是Intelligent Power Device,即“具有智能功能的电源器件”。根据制造商的不同,其叫法也不一样,有时也被称为 Smart Switch、High-side /Low-side Switch 等,那么怎样才算是“智能”呢? MOSFET和 IPD 的区别 当提到半导体开关时,通常就会想到 MOSFET。IPD 的基本功能是开关,内部结构 (芯片) 的大部分...
特性:P沟道MOSFET的开关速度相对较慢且导通电阻较高,但其在高边开关(High-Side Switch)应用中具有独特优势。由于P沟道MOSFET需要从栅极到源极的负电压才能导通,因此它可以在高电位侧控制电路的通断而无需额外的电平转换电路。此外,P沟道MOSFET的阈值电压为负值且导通电阻相对较高。 应用:P沟道MOSFET在汽车电子、工业...
based on 25Khz fs, and when i test the circuit, i use waveform generator set as 25Khz fs, 50% duty cycle, and when i switch high side mosfet, first i check the bootstrap capcitor, the volatge is 7-8volts around, and then i see the vgs waveform of high side mosfet, like this...

As the high-side switch switching rates are increased, the power dissipation increases proportionally in the clamp. The inductive clamp must be selected to allow dissipation of the power dissipation during the highest switching rates. The inductor discharge current...
