I am very familiar with the operation of bootstrap drivers on MOSFET driver ICs for switching an N-channel high-side MOSFET. , 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724) 925-7272 Hybrid Integrated Circuit For Driving IGBT Modules Description: M57962L is a hybrid integrated circuit designed for driving n-channel IGBT modules in any gate amplifier application. com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. The gate driver must be located very close to the IGBT module to minimize stray inductance between the gate driver and IGBT module. IGBT/MOSFET Gate Drive Optocoupler APPLICATION NOTE Application Note 91 www. The driving frequency is limited by the speed of the optocoupler. DEVELOPMENT APPROACHES Figure 1 is the block diagram of the IGBT gate driver circuit (IGBT trigger) that we developed. Despite various floating channel MOSFET/IGBT driver ICs being available, a transformer-coupled gate drive is still the better option to use for high power applications. 04/07 General Description The VLA504-01-01 is a hybrid integrated circuit designed to provide gate drive for high power IGBT modules. The use of faster switching devices minimizes the energy lost in the transitions from ON to OFF and vice versa, but it can create problems with radiated electromagnetic interference. Thereby a failure (short circuit or interruption) has been detected for at least one IGBT module. A gate drive transformer isolates the gate drive circuit from the switch node when driving the MOSFET gate. capacitor when discussing drive circuits. TME has over 800 employees, who provide expert support at each stage of the ordering process. , which supply 98%, 1% of tlp350 respectively.
