In one embodiment, the method includes forming a gate structure on a first portion of the substrate having a well of a first conductivity. A source region of a second conductivity and drain region of the second conductivity is formed within the well of the first conductivity in a portion of...
mosfet gate driver
Choose the right gate driver for a mosfet Hi team , How can I understand wich gate driver can drive a mosfet healty during the miller plateu. Do we need calculate the required gate current to charge/discharge the mosfet or something like that? Can someone g...
Drive current and sink current Rise/fall time Gate drivers attempt to source as much current as possible as fast as possible in order to fully toggle a MOSFET into its ON state. Conversely, they also try to sink current as fast as possible in order for a MOSFET to drop into its OFF st...
Infineon has recently released the MOTIX™ 6EDL7141 3-phase motor control gate driver, which can operate up to 60 V and has over 50 programmable parameters using a built-in SPI interface. This allows configuration of PWM switching and braking schemes, protection modes, gate drive currents and...
A MOSFET is a field effect transistor (it uses an electric field to control current flow) fabricated as a metal oxide semiconductor, the most widely used production technology. In the power MOSFET field, silicon carbide (SiC) is also used, as it is ideal

Thus, the MOSFET type device of the present invention has both higher drive current when the MOSFET is turned on and lower steady state power dissipation when the MOSFET is turned off with a variable threshold voltage. 展开 收藏 引用 批量引用 报错 分享 ...
我们知道MOS的导通深度是和GATE的电压大小有关的,GATE电压虽然已到达门限值,但是电压不够高的话,MOS的Rds(on)很高,此刻的直通不会“炸管”,但是会表现为温升。此种情形很容易被忽视,所以对电路进行极限测试很重要,在极限测试时是比较容易发现MOS的异常温升的。
