Peak Current of Isolated Gate Drivers
A common question when considering which gate driver to use is, what is the peak current a driver can deliver? Peak current is one of the most important parameters in gate driver datasheets. It is generally taken as the ultimate metric for the drive strength of the gate driver. The time to turn a MOSFET/IGBT on and off relates to the current that the gate driver can deliver, but it doesn’t tell the whole story. This article discusses the issues with using peak current to determine gate driver selection and compares some common representations of peak current in datasheets.
