ADUM7234 Maximum output current?

Hello,

 

For the project I have I need a powerful gate driver which can supply a MOSFET with a gate charge of at least 350nC. The rise time of <500ns is required, so I need a driver that can hold source/sink current of 2A (3A or higher will be optimal) in every possible operating point.

 

The described maximum output current (pulsed) in the datasheet of the isolated gate driver ADUM7234 is 4A for a maximum period of 1s. I would like to know if this time (1 sec) is real, because this is 1000x better than the similar ADUM4223 (1 us). If the information in the datasheet is correct this pulse duration should be enough for my application, or?

 

Regards,

Penyo
